Areas of application for penetrating waterproofing for concrete

If the walls get wet in the task and it is decided to carry out the reconstruction, the penetrating waterproofing for the best choice. The composition is applied to a wet surface, which is not always possible when using other waterproofing materials. In this way, it is possible to form a high-quality hydrobarrier that reliably protects the base from moisture.

Attention! Penetrating compounds are widely used to protect residential and industrial buildings.

Most often, with the help of this type, cellars, bathrooms, walls and one- and multi-storey buildings are protected. The composition is used to protect surfaces exposed to ground, sewage, sea water. It is used for processing elements of coastal structures, moorings, river ports, subways, mines, storage facilities, underground utilities.

The principle of operation of penetrating waterproofing for concrete

After application to the surface to be treated, the composition begins to actively penetrate into the existing microcracks and pores. After contact with water, the mixture crystallizes, gradually filling the capillaries. As a result, crystals are formed that prevent the penetration of moisture and do not dissolve in water. This principle of operation makes it compacted with a high-strength film up to 3 mm thick, capable of resisting the effects of strong water pressure.

Attention! The vapor permeability of the base is preserved.

Penetrating action, reducing the water permeability of concrete, increases its strength characteristics. As a result, the service life of the structure is increased, the appearance of fungus and mold is prevented.

Attention! The composition is able to penetrate to a depth of 0.4 m.

General performance characteristics of penetrating waterproofing for concrete

The form of the composition offered by manufacturers may vary. Choosing suitable option consider the features and benefits of each type.

Liquid penetrating waterproofing for concrete: basic properties

Manufacturers offer not only dry mixes, which should be prepared shortly before application, but also liquid penetrating concrete mixes. These compositions are already ready for use. Easy to apply even on uneven build surfaces with a brush or roller. In terms of viscosity, the composition is close to PVA glue. In the process of application, a thin layer is formed that needs additional protection. As a result building construction made virtually impervious to water. However, it is rather difficult to provide uniform protection of the entire surface with this waterproofing material.

Coating penetrating waterproofing: distinctive features

According to its characteristics, this type is similar to impregnation. Coating penetrating waterproofing penetrates the base relatively shallowly, but at the same time provides effective protection - provided that no mistakes were made during the formation of the protective layer. A high-quality composition allows you to form a reliable coating with good adhesion, resistance to water and elasticity. The latter property allows it to retain its properties when new cracks appear in the monolithic base.

Penetrating waterproofing for concrete: advantages and disadvantages

The advantages of this type of waterproofing protection include:

• the possibility of applying from the inside to a wet base, which is especially important when processing long-used basements and semi-basements;
• increase the service life of the treated structure;
• versatility. Can be used in the construction of buildings for various purposes;

• reduction of terms repair work;
• environmental safety;
• protection of reinforced concrete structures against corrosion;
• resistance to mechanical and chemical stress;
• the possibility of application in a wide temperature range.

The disadvantages include:

• impossibility of processing, foam concrete and. In the first case, the necessary chemical reaction will not proceed. Only stitching is possible. For porous materials, the composition will not be able to completely fill the cells;

• the complexity of the preparatory work before applying the composition;
• high cost of mixtures.

Leading manufacturers of penetrating waterproofing

Many manufacturers offer quality products. When choosing the appropriate option, you should pay attention to the rating of manufacturers of penetrating waterproofing for concrete:

• "Penetron". 8/10. This composition has received the most distribution. It has been used for a long time in many countries, manufactured using a special patented technology. If we talk about what it is - "Penetron", then this is a composition based on quartz sand, into which a certain amount of active additives has been introduced;

• "Lakhta". 9/10. The manufacturer offers various options;
• "Kalmatron". 9/10. A versatile compound used to protect many substrates;

• "Hydrotex". 9/10. Consists of sand, cement and special additives. The manufacturer offers compositions for external and internal processing;
• "Crystallisol". 9/10. Consists of sand, cement and special additives.

The best penetrating waterproofing for concrete: tips for choosing

To purchase the composition, you should consider:

• usage specifics. Manufacturers offer compositions focused on continuous processing of the concrete surface, seams, as well as for prevention. For each type of treatment, the best will be its penetrating waterproofing for concrete;
• application method;
• the state of the foundation and the requirements for its preparation;
• the material from which the base is made;
• restrictions on the use of a particular composition.

The use of penetrating waterproofing for concrete on the example of dry mixes of the trade mark "Penetron"

Sweat trademark "Penetron" produces a whole range of penetrating waterproofing for concrete. The material can be used to protect horizontal and vertical bases. We offer you to get acquainted with the peculiarity of the use of the composition and the formation of a hydrobarrier.

The average consumption of "Penetron" per 1 m 2 of waterproofing

The cost of waterproofing materials directly depends on the consumption. For 1 m 2 of base, an average of 0.95 kg of Penetron waterproofing is required if the insulation is applied in two layers. If the surface is uneven or there are a large number of defects, the consumption increases. The additive for concrete "Penetron Admix" consumption per 1 m 3 reaches 4 kg.

Preparation of dry waterproofing penetrating capillary mixture brand "Penetron"

In order to prepare a solution with high quality, you should carefully read the instructions attached to the Penetron waterproofing. As a rule, they do this in the following sequence:

• we measure the mixture and water in a ratio of 2 to 1 to prepare a sufficient amount of solution. The volume of the prepared solution is chosen so that it can be applied to the base within half an hour;
• pour water into a dry preparation of a penetrating capillary waterproofing mixture of the Penetron brand and mix everything thoroughly to obtain a homogeneous system;
• we control the plasticity and mobility of the prepared solution.

Penetrating waterproofing has been known for a long time. Back in the days of the USSR, special compounds based on sodium methyl siliconate were used, which were impregnated with the surfaces of concrete, masonry and brickwork. As a result of the chemical reaction of the substance with carbon dioxide, an insoluble polymer gel was formed, which filled the pores of the material from the inside. The water resistance, strength and frost resistance of concrete or brickwork increased several times, and, accordingly, the service life of the material also increased. After all, it is the impact of moisture and adverse weather conditions that is the reason for the rapid destruction of any building made of concrete or brick. Previously, such waterproofing was practically not used in everyday life, for example, to protect the floor in the bathroom from possible leaks, as they do now.

Recently, penetrating waterproofing for the protection of foundations, pools, bathrooms, basements and other structures that can be constantly exposed to the harmful effects of moisture has become increasingly popular in a professional environment. And there are very good reasons for this. Let's look at all the advantages of such waterproofing.

What are the advantages of penetrating waterproofing over roll and mastic materials?

Foundation - essential element, the basis of any structure. And if it is not reliably protected from the effects of adverse factors, the life of the building will be significantly reduced. The action of groundwater on an unprotected concrete foundation can reduce this period to several years. After that, the house will begin to gradually collapse: humidity will reign in the rooms, cracks will begin to appear on the walls, and mold will start in the dark corners. Neighborhood with wood lice and mold colonies can hardly be called pleasant, but these are still “flowers”. The impact of groundwater on the foundation can lead to the collapse of the building - this is really serious.

To avoid a sad scenario, at the stage of foundation construction, you should take care of its reliable waterproofing. The use of special roll coatings and bituminous mastics does not completely solve the problem.

Disadvantages of mastics and roll materials compared to penetrating waterproofing:

• Rolled and mastic materials protect the structure only from the application side;
• Any marriage or damage to the protective layer can lead to the penetration of moisture into the surface of the concrete;
• The presence of seams in rolled insulation is its most vulnerable point, because the material has to be laid in two layers to cover the surfaces of the seams, and this significantly increases the consumption and cost of work;
• If the groundwater level is high enough, the service life of rolled insulation can be reduced to three to five years;
• The main disadvantage of mastic waterproofing is also its fragility;
• If the work is carried out after the construction of the house, then coating and roll-type insulation require mandatory digging of the outer wall.

Penetrating foundation waterproofing easily solves all these issues. Why? Its action is based on a completely unique principle. The composition of dry mortars for waterproofing can vary, but usually it is a cement mixture with the addition of quartz sand and chemicals that have the ability to penetrate deep into the cellular structure of concrete. Where, during a chemical reaction, crystals are formed that densely fill the pores of the material from the inside. These crystals become part of the concrete structure, compact it and prevent water from penetrating.

The main advantages of penetrating waterproofing:

• At the construction stage, the penetrating waterproofing of the foundation is provided by adding a dry mix of the Penetron Admix type (or other brands) to the composition of the concrete to be mixed. This changes the structure of concrete, turning it into a qualitatively different material. The foundation will be protected from the impact of groundwater throughout the entire thickness of the structure, regardless of their depth;
• Such waterproofing works as long as the concrete "lives", because the material itself becomes waterproof;
• The crystals formed inside the cells have the ability to “self-heal”: if water still penetrates into the materials during operation, the formation of crystals resumes, and the concrete “heals” itself;
• The terms of construction or repair work are reduced, because. when using penetrating waterproofing, there is no need to thoroughly dry the concrete. The mixture must be applied to a wet surface, and the higher its humidity, the faster chemical reactions occur with the participation of active components;
• Concrete retains all technical characteristics: setting speed, air permeability, mobility, frost resistance, and so on. It "breathes", remains vapor-permeable. Materials treated with penetrating type waterproofing compounds only significantly change their water resistance characteristics;
• If waterproofing work is carried out after the completion of the construction phase, then this type of insulation will allow you to carry out all the necessary manipulations without digging out the foundation of the house. Processing of the structure can be carried out from any side, including from the inside;
• Penetrating waterproofing is effective in any direction of water movement and its pressure level;

Penetrating waterproofing of the entire surface of the masonry, all seams and joints prevents the penetration of acidic and alkaline aggressive environments, microorganisms and fungi into the thickness of the concrete; protects materials from the effects of salty sea water, ground and Wastewater with different content of harmful components.

Disadvantages of penetrating waterproofing

Alas, they have not yet come up with an ideal protection for concrete structures from the effects of water, which destroys the material from the inside. Despite all its remarkable characteristics, penetrating waterproofing has its drawbacks. Let's talk about them in more detail:

• Penetrating materials cannot be used as the only shield against moisture. Protection must be comprehensive. Additional processing of seams and joints with special mixtures is needed to prevent moisture from seeping through these vulnerable spots;
• The cost of penetrating waterproofing is relatively expensive, the current price now varies between 2-5 dollars per 1 square meter depending on the brand of the mixture;
• Waterproofing both inside and outside the building requires difficult preparatory work, for example, concrete walls must be absolutely clean, well-moistened, smooth, treated with acidic solutions. Waterproofing painted or rendered walls requires careful removal old paint, plaster fragments. As well as degreasing, cleaning with sand or water pressure under high pressure, processing with iron brushes. Full access to the capillary system of concrete must open, otherwise the waterproofing will be ineffective;
• The walls must be free from cracks and damage, therefore, such waterproofing is not used on old leached structures; small cracks and cracks are carefully sealed with cement mortar;
• The concrete surface is thoroughly cleaned of mold, oil stains, soil and even dust;
• Penetrating waterproofing is ineffective for walls made of aerated concrete and foam concrete, because. the size of the cells in the structure of the materials is too large, and the crystals will not be able to tightly close them from the inside;
• Penetrating mixtures are ineffective on the surface of the brickwork, because the brick lacks the element necessary for the chemical reaction. Only the surfaces of the seams can be treated with waterproofing mixtures, because. in masonry mortar there are cement hydration products. The problem of masonry waterproofing is usually solved with the help of external protection, where roll and coating materials are used;
• The solution for processing the wall of the floor must be used within half an hour, therefore it is prepared in small portions - water cannot be added to the finished mixture;
• Treated walls and floor surfaces must be well protected from drying out and exposure to low temperatures. The rooms must be warm, and the walls and floor surface are either covered with a film or thoroughly moistened over the next two weeks.

Important! Penetrating waterproofing of brickwork is carried out only by qualified workers, using special equipment.

As they say, there is no perfection in the world. But still, it is penetrating waterproofing that is the most reliable and effective tool protection of any concrete structures for industrial and domestic purposes: swimming pools, bathroom floors, foundations, basements, hydraulic structures, mines, reservoirs, piers, etc. And it has remained so for many years.

Application area

Penetrating mixtures are used wherever protection of concrete structures from moisture is required: sewage and ground water, sea water, etc. This protection proved to be excellent in various areas of construction. The chemicals that make up dry mixes are safe for human health, so they are widely used for waterproofing wells, drinking water tanks, swimming pools, and bathrooms.

Mixtures are effective when applied even from inside buildings. For example, penetrating basement waterproofing is effective to protect against groundwater, even without additional application to the foundation walls. This reduces the cost and duration of repair work, because the foundation does not need to be dug out, dried thoroughly, as is done in the case of using rolled and mastic waterproofing systems.

The non-toxicity of the mixtures allows them to be used in living quarters: in the bathroom to protect walls and floors from the harmful effects of moisture, in living quarters ground floor, etc.

Important! Any finishing work should be postponed until the crystallization process takes place. Apply any type of plaster, including gypsum, or other decorative finishing materials on the surface treated with waterproofing compounds, it is possible not earlier than after 30 days.

If you do not withstand the right time before the start of finishing work, the finish will be hopelessly damaged.

Popular building mixes for penetrating waterproofing

Penetron

Penetrating waterproofing Penetron is a patented building mixture that has been used in construction around the world for more than 50 years. This is a special cement mixture, which includes quartz sand and active chemical components. Its market price is slightly higher than the average for competitors: the cost of 1 kg of dry mix today is 4-5 dollars. And the consumption of dry mix for processing concrete walls, floors, foundations of buildings is approximately 1 kg per square meter. In general, Penetron is not a cheap pleasure, although reviews say that it is worth the money. Of course, in the event that a high-quality patented mixture is really purchased, and not a cheap fake, which are often found on the Russian market.

Building mixtures of the brand are widely used for industrial and domestic purposes. In everyday life, the protection of swimming pools, basements, foundations and bathrooms gives excellent results.

You can learn more about Penetron by watching the video. The video clip describes in sufficient detail the principle of operation of penetrating waterproofing. Also from the video you can learn about the rules for applying a waterproofing mixture, about the preparatory process before starting work, and about all subsequent stages.

Important! It is better to purchase building mixtures of the Penetron family from reliable sellers, because it is this brand that most often becomes the object of falsification.

Crystallisol

The principle of operation of all waterproofing mixtures is the same: active substances penetrate the intracellular structure of concrete, where a chemical reaction occurs with the calcium salts in it. Further, crystals grow, which tightly close the pores of the material, ensuring its water resistance. Crystallisol works on the same principle, and its composition also includes river or quartz sand, special cement and proprietary chemicals that the manufacturer prefers to keep secret. The Crystallisol mixture is also applied to a moistened concrete surface in the same way.

Of course, all mixtures for penetrating insulation are certainly compared with Penetron, which can be understood - for quite a long time it simply did not have worthy analogues. However, the reviews of professionals indicate that Crystallisol, which, by the way, is produced in Russia, is practically not inferior to the famous brand. And in some ways it even excels. For example, Penetron has no analogues of the plaster waterproofing mixture, which is used to repair and restore destroyed concrete structures, and which the Russian Kristallizol can boast of. And, of course, a reasonable price. Mixtures of the Crystallizol group are produced in Russia, therefore their market value is lower than that of Penetron. The cost of 1 kg of dry mix Crystallisol today is approximately 1 dollar.

Kristallizol mixtures are used to protect any concrete structures exposed to permanent or temporary harmful effects of moisture. Good results are obtained by protecting swimming pools, bathrooms, any water reservoirs, foundations, walls and floors in basements located below the groundwater level.

You can learn more about Kristallizol waterproofing materials from the video. In a rather long video, they talk in detail and in an accessible way about the benefits of penetrating waterproofing of this brand.

Lakhta

Another popular and high-quality Russian brand is Lakhta. They have a fairly wide range of dry building compounds that perform a variety of tasks. The principle of operation of the penetrating waterproofing compound Lakhta is the same as that of Crystallisol or Penetron: active substances enter the concrete structure, a chemical reaction occurs, and the pores of the material tightly close the crystals. The liquid mixture is also applied to a pre-moistened and carefully prepared surface in the same way.

The price offered by Lakhta is slightly lower than that of its foreign counterpart, but higher than that of the Russian Crystalisol. On average, today the cost of a waterproofing mixture Lakhta is approximately 2-3 dollars per 1 kg. Reviews of ordinary consumers and professionals in the field of construction indicate that in terms of its properties, Lakhta is practically in no way inferior to its famous competitor.

Lahta waterproofing mixtures are used to protect residential buildings and industrial facilities. Good results are obtained by the use of dry mixes for waterproofing pools, wells, bathroom floors and walls, balconies, basements and foundations.

You can learn how to properly prepare a waterproofing solution using the Lakhta mixture from this video. The video will also tell you how to properly prepare the concrete surface, in what proportions the dry mortar and water should be combined, what consistency the liquid mixture should be, and other important nuances.

Element

Another popular brand is Element. Produce dry building mixes Element in the Russian city of Stavropol. The product line of the Element brand includes: water repellent, elastic waterproofing, penetrating waterproofing and liquid rubber to protect the roof from water. The element is distinguished by a fairly affordable price: on average, the cost of 1 kg of dry building mix Element on the Russian market is 1.5 dollars.

The penetrating waterproofing of this brand can be used for domestic and industrial purposes to protect concrete structures from the outside and from the inside. It is used for waterproofing balconies, basements, pools, floors and walls in the bathroom. And also for the protection of tunnels, mines, reservoirs, hydraulic structures. And wherever it is necessary to preserve concrete structures with the constant harmful effects of ground and waste water, sea water, and precipitation.

The construction of any house begins with a foundation that needs protection from moisture and groundwater. To do this, a number of measures are taken to waterproof the foundations of houses, using all kinds of roll coatings, mastics, sealants, etc. Such materials should serve as a reliable barrier against water.

Recently, the so-called penetrating waterproofing. What it is and what advantages it has will be discussed in this article.
Most often, roll coatings or bituminous mastics are used to protect the foundation from moisture, which require certain knowledge and experience during installation. A small defect in the construction of a protective barrier of the foundation based on these materials can lead to serious consequences. Moisture will penetrate through the walls of the foundation, which will lead to premature destruction of concrete, a decrease in thermal insulation properties, constant dampness in the basement or basement.

Traditionally, waterproofing is done outside the strip foundation, at the stage of laying the house. What to do when your house is already fully built, and water seeps through the concrete walls in the basement.

The first step is to determine the cause of the leak. The most common causes are breakthrough water pipe or poor waterproofing protection. If it is quite simple to eliminate a leak in a pipe, then it is very time-consuming and expensive to re-do the waterproofing of the foundation. To do this, you will have to dig out the entire house around the perimeter, drain the concrete structure, clean it of dirt, find a leak, and then put a patch. True, after a few years a new leak may occur and the whole process will have to be repeated again.

Therefore, there was penetrating waterproofing for concrete and foundations, which can be applied from the inside, unlike traditional materials that are applied only from the outside. This does not require special skills, and all the work can be done independently, without the involvement of hired workers.

Untreated concrete foundation walls are not a serious obstacle to water, therefore, in the absence of good protection, sooner or later it begins to seep into the basement. Water can also seep through cement joints between foundation blocks or through joints in masonry. The fact that it is problematic to eliminate these leaks after building a house is written a little higher. In such cases optimal solution there will be a penetrating waterproofing on concrete from the inside or from the residential side of the room.

This material is a mixture of high-quality cement with the addition of ground quartz sand and special additives that perform the main function of concrete waterproofing.

The principle of operation of penetrating waterproofing is as follows - when the mixture is applied to foundation walls or concrete surfaces, chemically active additives begin to penetrate through capillaries, and upon contact with water form insoluble crystals that fill voids, pores, microcracks. Thanks to this, concrete structures become waterproof, more dense, durable and frost-resistant.

If, when protecting concrete, and in particular the foundations of buildings, from water with polymer-bitumen mastics, roll or polymer coatings, a dry surface is required, then for penetrating waterproofing, on the contrary, it is necessary that the material be well moistened. due to contact with water, there is an active growth of crystals in the pores of concrete.

Penetrating compounds can be applied both inside and outside the structure. Thanks to chemical processes, concrete itself acquires the property of water resistance. This is the fundamental difference between penetrating waterproofing and other types.

Scope of application of penetrating compounds

Due to its properties and ease of application, penetrating waterproofing has become widespread not only in the construction of houses, but also in the construction of pools, cellars, bathrooms, wells, i.e. for structures exposed to water.

It can be used both outside and inside, at the beginning of construction, and during subsequent repairs, therefore it is practically indispensable for protecting the walls and floors of basements in already built buildings, where it is problematic to carry out external waterproofing.

In monolithic construction or when constructing a swimming pool, penetrating waterproofing can be added to the concrete mix, which will make the cured concrete waterproof. This method is used in the construction of dams, tanks for oil products, berths, bridges, sewers, pumping stations etc. This list can be continued for a long time. As you can see, the use of such compounds is quite wide.

Unfortunately, many people still do not know about this type of waterproofing and use various bitumen-based coatings. The disadvantage of bitumen-containing materials is that when applied from the inside, they do not withstand water pressure and therefore cease to perform their function. In addition, when the soil shifts or shrinks, the external traditional bitumen protection can receive mechanical damage, which will render the entire foundation waterproofing system unusable.

Application of penetrating waterproofing

1) The first thing to do is to prepare the surface for applying penetrating waterproofing. This can be done mechanically or chemically. Regardless of the preparation method, it is necessary to get rid of efflorescence on the concrete surface, which greatly prevent the composition from penetrating deep into the structure. With the mechanical method, you can use a drill or grinder with a hard metal brush.

A more advanced method is the use of high-pressure water-jet machines, which quickly and effectively remove efflorescence from large areas. During this processing, it is necessary to use a protective suit and a respirator.

With the chemical method, special compounds are used that are applied to the surface and dissolve efflorescence on the concrete surface.

Of all the preparation methods, the simplest, most effective and economical is to clean the surface with a grinder or drill. As a rule, everyone has these tools, and it is expensive to buy or rent water jet machines, and sometimes there is nowhere. In chemical processing, you will have to spend money on reagents that are not cheap.

2) The second important step is the saturation of the treated surface with water. This must be done especially carefully, because the quality of the impregnation determines how deeply the composition of the penetrating waterproofing penetrates into the concrete. It is necessary that one square meter of surface absorb at least 5 liters of water. You need to do this in several visits, i.e. spray the surface with a spray bottle, wait until everything is absorbed and repeat the process again.

3) The final step is to apply the mixture to the surface to be treated. Usually the method of application is written on the package with penetrating waterproofing. If there is no such instruction, then the composition is applied in two stages. The first layer is rubbed with a hard sponge or brush, and the next layer is applied perpendicular to the previous one with a spatula or brush, depending on the consistency. There are also liquid mixtures that can be applied with an airbrush.

Approximately one hour after applying the finishing layer, it is necessary to re-moisten the concrete surface.

If all work is done carefully and in compliance with all technologies, then the concrete becomes waterproof to a depth of 400 mm. The strength of concrete increases, the number of freeze and thaw cycles increases.

Penetrating waterproofing device for masonry

There are situations when it is necessary to protect brick walls from moisture. But penetrating waterproofing is designed to protect materials based on cement-sand compositions, and it is not able to penetrate deep into the brick. What to do in this case?

To do this, make the so-called waterproofing plaster. It is set up as follows:

On the brickwork a plaster mesh is attached with a cell size of 50x50 mm, at a distance of 15 mm from the wall;

The surface is plastered with a cement-sand mixture. In this case, plasters based on gypsum or lime should not be used. The thickness of the plaster layer must be more than 40 mm;

A day later, a penetrating waterproofing composition can be applied.

As a result of these actions, a protection against water is formed, the thickness of which is the thickness of the plaster layer. The reliability of waterproofing in this case depends on how well the plaster adheres to the brickwork.

Benefits of penetrating waterproofing

Summing up, we list the main advantages of penetrating waterproofing, which distinguish it favorably from traditional materials:

• the composition can be applied from the inside and outside;
• the vapor permeability of the structure is maintained;
• ease of application, no special knowledge is required;
• possibility of application in already constructed buildings;
• frost resistance, durability and strength of concrete structures increase;
• can be applied to a damp surface;
• environmentally friendly, therefore it is used for the construction of swimming pools and drinking water tanks.

Now on the market there are materials from various manufacturers. The most common are Penetron, Lakhta, Xypex, Drizoro, Hydrohit, Antihydron, Crystallisol, etc. All penetrating compounds differ slightly in their technical characteristics, method of application and price. Therefore, before buying, it is better to consult with specialists from various manufacturers in order to obtain more reliable information.

Which is better, breaking or penetrating basement waterproofing?

Basement waterproofing is a set of works designed to remove moisture, fight fungi and mold.

Protecting the surface from the negative effects of external factors prolongs the service life of the structure and increases the reliability of operation. It is carried out using special waterproofing mixtures with improved protective properties.

Waterproofing methods

Depending on how the mixture is used, there are two ways to waterproof the basement of a house - penetrating and lubricating.

Based on the operating conditions of the premises is selected temperature regime and climatic conditions, the optimal approach to surface protection.

Breakthrough waterproofing

Special mixtures of deep penetration of cement-polymer material are used.

Waterproofing for concrete - improving the performance of buildings and structures

For waterproofing basements, you can use the following mixtures of cement and polymer:

• Penetron;
• "CT prestol-1";
• "Penetrate"
• "Kalmatron".

Benefits of water penetration:

• Ease of use of cement-polymer mixtures (only the surface must be cleaned).
• Large penetration depth (up to 50 cm).
• Long service life (the same period of operation of concrete and reinforced concrete structures).
• Relatively low costs.

Lubricant waterproofing

Bitumen-polymer or bitumen-rubber sealants are used, which form a strong film on the surface with a thickness of 1 to 3-5 mm.

The rate of polymerization of the components of the mixture depends on the surface temperature and the concentration of chemical reagents. The sealant has excellent adhesive properties, which significantly increases the service life and improves the protective properties of the waterproofing coating.

Depending on the operating conditions of the building and the required level of protection, the following mixtures can be used:

• "Penetrat Elast";
• "CT prestol-10 1K";
• "UNIS Hydroplast";
• Knauf Flachendicht.

Advantages of lubricating insulation:

• It can be used on surfaces that are in direct contact with water.
• The number of layers depends on the working conditions of the room and can vary from 1 to 4-5.
• It provides full protection of the room with negative pressure up to 5 atm.
• It maintains integrity when cracks appear up to 2 mm.

Which one is better?

Durable waterproofing is used to protect the surface from mold, mildew and moisture under normal operating conditions, while lubricant is used for more extreme conditions (direct contact with water, high pressure).

Regardless of how basement waterproofing is done, the characteristics of the building, operating conditions, climatic conditions and the required level of protection must always be taken into account.

The final decision can only be made by a qualified specialist who has carefully studied this issue.

Concrete waterproofing

Concrete waterproofing is a process that creates concrete surfaces such as slabs, walls, floors, etc. It becomes waterproof. Exist various ways waterproofing.

concrete

Concrete is construction material, consisting of cement, water, many fillers, reinforcing components, chemical and mineral additives.

Sand and gravel are used as fillers, while metal-based equipment as well as glass and plastic fibers are used for reinforcement. Chemical additives make it possible to produce concrete with special properties.

Mineral additives are used to increase the strength of concrete. In addition, additives, which are usually the main component of concrete, can be used instead of Portland cement.

Waterproofing system.

For concrete, there are two main waterproofing systems - a complete waterproofing system and a system based on the use of waterproofing membranes.

The complex waterproofing device system includes two subtypes: hydrophilic and hydrophobic waterproofing device systems.

There are various ways of hydrophilic waterproofing, among which the most common crystalline waterproofing device. This method is based on the transformation of water into concrete into insoluble crystals.

The activity of many hydrophilic waterproofing materials is based on its properties in contact with water, absorbing it, expanding it when exposed, and thus filling the pores with concrete, making it waterproof.

Hydrophobic waterproofing systems are based on the use of various waterproofing coatings, membranes, etc., which are used from outdoor insulated structures.

membranes

Waterproof membranes are liquid and sheet metal.

What is breakthrough concrete waterproofing

Liquid membranes are applied to concrete and form a rubber coating 6 mm thick. The main advantages of this waterproofing method are high performance and low cost applications.

Sheet membranes are made of bitumen. Such membranes are laminated with polyethylene film, and the resulting leaves are glued to concrete. It is a very durable waterproofing material. Sheet membranes are used for waterproofing foundations, underground parking spaces, tunnels, etc.

The main disadvantage of sheet membranes is that they are glued by hand,
leading to higher labor costs.

hydrophobic concrete

Unlike hydrophobic membranes, "hydrophobic concrete" is a completely new cutting-edge technology.

It is not based on the waterproofing of precast concrete structures, but on the production of waterproof concrete. Hydrophobic concrete is obtained by introducing special additives also at the stage of its production. These additives prevent capillary infiltration of water into the concrete, making it waterproof. Such concrete is successfully used in Asia, Europe and Australia, which has proven itself among builders, as it allows you to build construction even in the rain.

Crystal waterproofing for concrete

The crystalline waterproofing device is one of the options for creating an integrated waterproofing system.

Let's see how it's done. Firstly, the proportion of the concrete surface created by the sealant is wetted with water and then applied to the base layer, the mortar has a low density and then coated with a waterproofing crystalline material, which is a high density mortar.

After that, the process of chemical diffusion begins. The high density crystalline waterproofing mortar penetrates the concrete into the low density mortar until a balance is reached. After water enters the concrete, the hydration of the cement begins. The hydrated cement reacts with the crystalline waterproofing material in the concrete.

During the diffusion process, the crystalline waterproofing material penetrates the concrete up to a depth of 30.5 cm. This waterproofing method is very effective because the crystals in the concrete are protected from any external damage.

Another advantage is the thermal resistance of the structure in its unmodified state up to 130 degrees. In addition, when a waterproofing device is installed, the resistance of the chemical structure of the reaction, such as carbonization, increases, resulting in a decrease in the suction and destruction of concrete; prevents the diffusion of chloride ions into the structure, which protects the reinforcement found in concrete from corrosion and expansion.

Waterproofing Concrete Injection

In some cases, concrete injection technology is used to repair concrete structures.

This method is based on filling formed cracks due to shrinkage with polyurethane or epoxy resins. She somewhat resorted to the introduction of concrete containing cement-containing injection materials. Pressure waterproofing is recognized as the most effective and fastest way to repair concrete structures from leakage.

With your help, you can stop a serious water infiltration within minutes. The disadvantage of this technology is the high cost of materials used for waterproofing.

Before proceeding with the preparation of waterproofing concrete...

Before proceeding with the installation of waterproofing, it is necessary to consider a number of important factors.

The concrete surface must be thoroughly cleaned. It is necessary to remove construction waste, etc., measure the rough surfaces and glue the shells to the concrete, and then turn off the dust. Make sure the waterproofing material can be used with a mortar that is used to seal the shell and does not cause a chemical reaction that could cause the concrete to break. Some of the materials used for waterproofing are flammable and precautions must be taken when working with them.

Penetrating waterproofing

Recently, quite often there are cases when penetrating materials are used as the main waterproofing element, which NOT RIGHT.

Penetrating compounds can be used as one of the elements in the chain of systemic waterproofing materials, but not as the main one.

Penetrating waterproofing for concrete

These materials are easy to use, effective when a new structure has leaked (basement, underground garage, etc.), but consider them as a universal remedy for all cases - NOT RIGHT, especially since they also have limitations (large pores, old leached concrete, etc.).

When repairing an old base, when the external pores are oily or clogged, it is necessary to thoroughly clean the surface of plaster and degrease it, opening access to the capillary system.

Moreover, this cannot be done with a simple iron brush - it must be cleaned thoroughly, preferably with sand or high-pressure water. There are other significant points that limit the use of penetrating waterproofing.

The problem of waterproofing foundations in active contact with water, as well as in cases with limited access to the outside of the foundation, is that the use of traditional waterproofing materials does not always lead to effective protection against water and moisture.

To further enhance the waterproofing properties of a concrete structure (foundation), waterproofing is recommended to be made of penetrating materials from the inside of the protected structures (basements).

Penetrating waterproofing- cement-sand mixture with the use of chemical additives.

The fundamental difference between penetrating compositions and all other materials is the formation of a waterproofing layer not on the surface of the foundation, but in its considerable thickness (the penetration depth of active chemical components can reach 10-12 cm).

Application

• waterproofing of surfaces of concrete and reinforced concrete structures;
• waterproofing of foundations and basements that are actively in contact with water;
• in combination with surface waterproofing of the foundation at high level ground water.

Advantages

• improving the water resistance of concrete structures (and ONLY! concrete);
• formation of a waterproofing layer in the mass of concrete;
• the possibility of processing the outer and inner surfaces of the structure, regardless of the direction of water pressure;
• applied to a damp surface, there is no need to dry the concrete.

The main advantage of penetrating materials is the ability to protect the structure from the inside from the penetration of moisture from the outside.

Therefore, this type of waterproofing has found wide application in the reconstruction of basements and semi-basements, when it is no longer possible to perform external waterproofing.

LIMITATIONS

• used for waterproofing on crack-resistant concrete structures;
• does not provide anti-capillary protection of brick walls (due to the absence of substances necessary for the reaction in the brick);
• not used for waterproofing walls made of porous materials (foam concrete, aerated concrete, etc.) due to the large pore size;
• it is not recommended to apply prefabricated foundation blocks to foundation blocks (the joints between them are a problem).

Penetrating waterproofing: pros, cons>>>

The combination of penetrating waterproofing on stable foundations and elastic waterproofing on foundations subject to deformation can solve many waterproofing problems in the repair and reconstruction of underground structures.

Penetrating waterproofing mechanism

The waterproofing mixture is mixed with water and applied to the wet concrete surface.

The effect of waterproofing is achieved by filling the capillary-porous structure of concrete with insoluble crystals.

Active chemical additives that are part of the material, penetrating into the concrete, enter into a chemical reaction with the components of the concrete mixture, forming insoluble compounds (crystals), which create a continuous barrier that prevents the ingress of water.

The process of concrete compaction develops in depth upon contact with water molecules and stops in its absence.

Upon new contact with water, the reaction resumes.

The depth of penetration into the concrete body of active chemical components can reach tens of centimeters. Micropores, capillaries and microcracks with a width (diameter) up to 0.3-0.4 mm, filled with products of chemical reactions, increase the water resistance of concrete by 2-3 steps.

As a result, penetrating waterproofing becomes integral part concrete, thus forming compacted waterproof concrete.

During construction, experts advise paying special attention to protection against moisture. For this, various mastics, bikrost are used. However, the builder does not always have enough experience to do everything right, which leads to the appearance first in, and then in residential premises. Not only is this moment very unpleasant and harmful to the health of those living in the house, moisture also destroys buildings. In this case, you can use this type of protection against water, such as penetrating for concrete. It can be used when the dwelling is already built, applying the compound from inside the basement walls.

A similar layer is applied from the inside of the room (most often in) to the walls and floor - they are most susceptible to getting wet. If instead similar material use the same bikrost, there will be no sense in the work - they will be useless. After a short time, the coating will swell, water will collect between it and the wall, which will even worse affect the state of concrete strength.

Penetrating compounds act differently. Soaking into concrete, like a sponge, they fill the smallest channels that are always present in. Further, meeting with water, the composition crystallizes, tightly clogging the channel and blocking the path of water. Thus, maximum protection against moisture penetration through the basement walls is provided.

Important information! Such compositions will be useless when applied to porous materials such as foam block. In this case, it is necessary to protect the structure from the outside as much as possible even at the construction stage.

Penetrating waterproofing for concrete: general performance and technical characteristics

Such a material may be coated or have a liquid consistency. Depending on this, the method of application is selected. Before starting work, you should understand what features each of these types has.

Liquid penetrating waterproofing for concrete and its features

Such material is sold in finished form. By consistency, it can be compared with PVA glue. The composition is applied quite simply - for this they use brushes, rollers or even sprayers, but there is one caveat: it is rather difficult to distribute such material evenly over the entire surface. In addition, the applied layer requires a separate protection.

Coating penetrating waterproofing and its advantages over liquid

The action of the coating mixture is similar to liquid impregnation, however, it does not penetrate so deeply. But if all the work was done correctly, the protection against water will be maximum. The advantage of such a composition is its high adhesion and elasticity, which allows protection against moisture penetration and subsequently, when new cracks appear in. If you talk about which penetrating waterproofing is better, then the use of coating insulating material would be a better choice.

Pros and cons of using such insulating materials

Like any other material, penetrating waterproofing for concrete has both positive and negative qualities. Now let's try to understand them. For the convenience of the reader, consider the qualities of the composition in tabular form.

Comparing the advantages and disadvantages, it can be noted that if the basement of the house is made of concrete, and the building has been built for more than a year, then the use of penetrating mixtures will not even be optimal, but the only right solution for a home master.

The consequences of poor waterproofing of concrete structures can be very deplorable, up to the collapse of the structure:

Leading manufacturers of deep penetration waterproofing for concrete offering products in Russia

There are a lot of manufacturers of such material, at the same time, there is no particular difference in the quality of the products of various companies, and word of mouth provides them with fame. One of the masters successfully used a certain brand, told a friend, and so on. Among consumers, the most popular are:

• "Penetron";
• "Lakhta";
• "Kalmatron";
• "Peneplug";
• "Penecrete";
• "Hydrotex".

Of course, the composition of each manufacturer has its own characteristics, but they are not global. The main components of such waterproofing are sand and special additives.

Which mixture can be called the best penetrating waterproofing for concrete

Definitely nothing can be said about this - the composition is selected based on the characteristics of the base, the necessary measures taken to prepare it, and the priority method of application. Therefore, for each specific case, you should choose certain compositions, the characteristics of which are indicated on the packaging.

The use of a dry waterproofing mixture on the example of a capillary penetrating composition of the brand "Penetron"

The compositions of this brand are quite diverse. We will give general examples so that the Dear Reader can more clearly understand how to use them and what it is - the Penetron mixture.

Average consumption of Penetron waterproofing per 1 m²

Consumption depends on how smooth the surface will be processed and the composition of the mixture itself. On average, about 0.9-0.95 kg of waterproofing compound per 1 m² is required. If there are significant irregularities, the consumption will naturally increase. If you use the Penetron Admix additive, the consumption per 1 m³ will be about 4 kg.

How to prepare a penetrating waterproofing for concrete "Penetron"

The preparation of the mixture is practically not difficult. The main thing here is to follow the instructions for preparing the Penetron waterproofing.

The algorithm of work is approximately as follows. First, the amount of the mixture necessary to process a certain area is kneaded at the rate of 1 part of water to two parts of Penetron. Do not immediately knead a large volume - the mixture must be used within half an hour. The composition is thoroughly mixed with a mixer and applied to the prepared surface.

Good to know! In the presence of significant cracks, the composition "Penetron Penekrit" is added to the mixture (instructions for use are on the package).

Comparison of prices for penetrating waterproofing "Penetron" and other brands of compounds

Compared to other mixtures, the cost of "Penetron" is slightly lower. For example, the price of the composition "Osmosil" 25 kg is from 4000 rubles. up to 4500 rubles, while the same amount of "Penetron" will cost 3100 rubles. The same goes for most other brands.
