Penetrating waterproofing for concrete is a mixture that is used to protect foundations and other parts of a building from moisture. It is used in both private and industrial construction. The composition of such a mixture includes cement, sand, and various chemical components. The depth of penetration of active substances into the concrete is 10-12 cm. This allows you to reliably protect the foundation from moisture and extend its service life.
Concrete blocks, which are part of the foundation, are exposed to moisture throughout the entire operation. Precipitation contributes to the erosion of the base of the building, which can lead to serious consequences. Concrete has microcracks, through which moisture penetrates, getting into the basement.
It is also worth noting that water passes not only through microscopic cracks in the concrete structure, but also through the seams that are located between the individual structural elements. These places are vulnerable and also need reliable protection. Brickwork is not self-resistant to moisture.
In order to protect the foundation or any other structure (for example, a garage floor made of cement), it is customary to use penetrating waterproofing for concrete. It is most often applied during the construction phase of a house. But in the case when the house has already been built and there is a problem with moisture in the basement, then the waterproofing is applied from the inside.
The principle of operation of the protective composition is simple and straightforward. After its application to concrete, the process of absorption of chemical additives through microcracks begins. In case of contact with water, the mixture filling the capillaries of the block crystallizes. These crystals fill the empty space and prevent subsequent moisture penetration. It is important to note that they do not dissolve in water.
Useful information! In addition to waterproof qualities, such an impregnation strengthens the concrete material, making it more durable and wear-resistant.
To apply such a mixture, a wet surface is required, which distinguishes it from roll coatings and bitumen-based mastics. Before you buy a penetrating waterproofing for concrete, you should clearly understand the principle of its action.
Penetrating mixtures protect the foundation not only from moisture, but also from mold and mildew. The process, which is based on the interaction of free lime and moisture, allows you to reliably close the pores in the concrete structure and protect the structure from destructive factors.
To accelerate the process of penetration of waterproofing substances into the concrete material, it is necessary to apply the composition to a wet surface. This method is very popular when it is necessary to carry out the reconstruction of the premises. Often, penetrating compositions are used when it is not possible to apply another method of protection.
Penetrating substances are actively exploited to protect the foundations of private residential buildings from moisture. Industrial building are also included in the list of objects that are processed with this type of waterproofing. Objects can be exposed to high humidity:
This waterproofing material for concrete is not very popular, as some people simply do not know about its existence. However, the application of bituminous mastics is accompanied by certain difficulties, since they harden very quickly. In turn, roll materials do not guarantee one hundred percent protection of concrete from the destructive effects of moisture.
Waterproofing of any structure can be carried out even at the construction stage. Moreover, many experts recommend using this particular method. It takes into account the addition of dry matter to the cement slurry. Such a mixture affects the structure of the future foundation, the waterproofing properties of which are manifested from the very beginning.
Concrete additives for waterproofing help to protect the foundation from the effects of precipitation and water in the ground at all points without exception. The operational life of this insulation will be equal to the shelf life of the foundation itself, since they are a single whole.
Note! Crystals that form in microscopic pores are resistant to water. They can collapse, allowing water to pass through, but even in this case, they recover over time. This type of regeneration provides a high degree of foundation protection.
An important advantage of such additives is their ability to speed up the process of building a house. This is because their use eliminates the need for concrete drying. Thus, time is saved due to the penetrating waterproofing for concrete. Reviews of such formulations are mostly positive.
When applying the mixture to a concrete surface, you need to know that it must be wet. Moreover, the higher this indicator, the faster the crystallization reaction occurs inside the pores. After processing, the material itself does not lose its properties, retaining all useful technical characteristics, such as:
The only indicator that undergoes a change after waterproofing is applied is water resistance. Such insulation is the most acceptable solution when it is necessary to protect the foundation of an already finished structure from moisture. This is due to the fact that it eliminates the need to excavate the base. You can buy waterproofing for concrete in a specialized store or place an order online.
The penetrating composition provides reliable waterproofing protection, regardless of which side it was applied to the foundation. Pressure groundwater in this case, it also has no effect on the quality of protection. The insulated surface, as well as all seams and butt points, become immune not only to moisture, but also to an aggressive environment with different Ph values.
Any of the existing insulation today has some disadvantages. The high performance of penetrating compounds makes them the most suitable for the protection of foundations and other structures, but they are not ideal. The main disadvantage of such mixtures is that they are recommended to be used in combination with other waterproofing agents. For example, to protect the foundation joints from moisture, it is recommended to purchase a special substance designed for this.
Another disadvantage of penetrating water insulation is that it is quite expensive. Depending on the brand and specialization of the mixture, the price of concrete waterproofing can vary from 50 to 350 rubles. for 1 kg.
Note! Typically, this type of insulation is sold in bags weighing 25 kg.
Before starting work on applying such a composition to the surface, it is necessary to carry out preliminary preparation. It is very important to clean the wall so that no (even minimal) dirt remains on it. Otherwise, the composition will not be well absorbed into the material. And it is also worthwhile to degrease the surface in advance. Experts recommend using a garden hose to clean the wall, as the water that comes out of it under pressure does this very well.
The cost of a waterproofing material can vary greatly depending on its type and brand. The most economical and reliable option is Lakhta penetrating waterproofing. You can buy such a mixture for a very reasonable price (80-100 rubles per 1 kg).
All of the above manipulations are necessary in order to provide free access to microscopic pores. If there are large gaps and cracks in the concrete walls, they must be repaired. It is recommended to cover up such defects with cement mortar... This option is the most acceptable and simple.
It should also be noted that waterproofing mixtures of this type do not work if they are used to protect the surface of the brickwork. With their help, you can only protect and strengthen the seams in such a structure. Thus, for brickwork, it is better to use the more common and familiar protection options.
Nevertheless, taking into account all the minuses, today there are no more effective remedy for waterproofing concrete structures. Before purchasing this composition, it is recommended to study the companies that manufacture it. This will allow you to choose the most reliable product for a very reasonable price.
Currently, the construction market abounds various materials designed to protect the foundation. Penetrating insulation for concrete is no exception. It is implemented by different companies, each of which has its own pros and cons. Experts do not recommend buying the cheapest formulations, since they are often not of high quality.
The middle price range is the most acceptable, since it includes good, high-quality brands of compositions. When choosing the right product, you should consult with the seller. And also, before you buy a penetrating waterproofing, it will be useful to study reviews about it on the Internet. Today, the following brands of penetrating mixtures are most common and effective:
The first option is the most common. It has been used for about half a century all over the world. Lakhta is distinguished by a variety of choices. And the mixture of the Kalmatron brand is considered the most versatile penetrating waterproofing. Pools, wells, cellars and balconies - all these structures can be protected by using the products of this manufacturer. There are many other brands that differ in their composition, application and action. However, the aforementioned companies have proven themselves best in the production of products for the protection of concrete structures.
Penetron brand building compounds are used not only for private, but also for industrial purposes. These mixtures have appeared quite a long time ago, and the effectiveness of their use has been tested by time. This mixture contains sand (quartz) and active chemical compounds.
The cost of such a penetrating composition is quite high - 250-300 rubles. for 1 kg. However, its technical characteristics fully justify the price. Penetron penetrating waterproofing allows you to protect not only the foundation, but also walls and floors made of concrete. The consumption of Penetron is quite simple to calculate, since about 1 kg of the composition is required to protect 1 m².
Note! Be careful, as domestic markets are filled with all sorts of fakes that can cost much less than the original. The quality of such mixtures is in question, so you should not save on waterproofing the foundation and other concrete structures.
Penetron penetrating waterproofing for concrete is used to protect wells, pools, floors and walls in bathrooms and garages from water. Before using such a composition, it is advisable to read the instructions and watch a training video in which all the nuances of the work will be described in detail.

The Lakhta brand is domestic, and its distinctive feature consists in a wide range of dry mixes used for concrete waterproofing. The products of this brand are used for various tasks, including for enhancing the waterproofness of the seams.
The principle of operation of such mixtures is the same as in the case of Penetron waterproofing material. Active chemical components penetrate into the pores of the concrete structure and crystallize when interacting with water. Before proceeding with the application of waterproofing Lakhta, it is necessary to prepare concrete surface.
The cost of this mixture is lower than the previous composition, but the products have a fairly good feedback... The price for 1 kg of the substance is approximately 120-180 rubles. In terms of technical characteristics, such insulation is practically in no way inferior to the composition of Penetron. The price of penetrating waterproofing Lakhta determines its popularity and prevalence in the construction market.
This mixture is used to protect industrial and domestic concrete structures from moisture. With the help of such waterproofing, you can strengthen the waterproofing of walls and floors in a cellar or garage. It is also actively used to protect swimming pools, bathrooms and balconies.
The composition of this brand allows you to quickly and effectively eliminate small leaks that destroy the foundation of the building. This mixture helps to strengthen the surface strength of the concrete material. A feature of the Kalmatron waterproofing substance is its versatility. Compositions of this type are used to isolate the following materials from moisture:
The price of penetrating waterproofing for concrete of this brand is the most attractive of all the brands presented. The cost of 1 kg of the product is about 80-100 rubles. Thus, for a bag, the volume of which is 25 kg, you will need to pay approximately 2000-2500 rubles. Such compositions can be used both during construction and during the operation of concrete structures. Domestic consumers note the rather good waterproofing properties of the Kalmatron compositions.
Useful information! Before purchasing this waterproofing material, you must consider one important point... It is not recommended to use it if the Ph level at the object is in the range from 3 to 11.
In addition to dry mixes, there are other ways to protect concrete structures from the harmful effects of moisture. One of them is the use of liquid waterproofing. Today you can find various in composition liquid materials of this type, however, the following are the most common:
These materials have both advantages and disadvantages. Before purchasing one of them, it is recommended to study the specifics of their use. Liquid products are much easier to work with, especially when compared with bituminous mastics, membrane films and roll products.
You can buy liquid waterproofing for concrete on the construction market, in a store or on the Internet. The cost of such formulations is about 2 times higher when compared with dry mixtures. Liquid substances that make concrete waterproof are also convenient because they can be applied to uneven surfaces.
The process of applying a protective composition itself is quite simple. It does not involve heating the mixture, as is the case with bituminous mastic. It is also worth noting that the quality of this type of waterproofing is very high. Among other advantages of a liquid mixture, one can single out the fact that it does not cause any harm to human health, since it does not emit active chemical compounds.
Liquid water insulation is resistant to high temperatures, so in summer period do not be afraid that it will start to melt. Such material is an excellent alternative to roll and other insulators.
Liquid glass for concrete waterproofing is applied using the following tools: brush, construction roller. The viscosity of the composition resembles the density of PVA glue. Such a mixture is applied in a thin layer, which, after drying, requires additional protection. This is due to the fact that the finished layer has poor resistance to mechanical stress.
This type of penetrating insulation achieves excellent results. Impregnations based on dry mixes increase water resistance, and liquid formulations make the concrete structure practically invulnerable to water. But this method also has some disadvantages. For example, making a layer of the required thickness with your own hands is quite difficult. Therefore, it is better to use the services of a professional.
Many people confuse impregnation with lined insulation. This is not surprising, since they are very similar in their properties. Both of these types of waterproofing must be applied to the surface of the structure, after which they penetrate through microcracks deep into the concrete. The difference between the impregnation and the coating mixture is that it protects the concrete from moisture, penetrating quite deep into the blocks. In turn, the coating mixture makes only the concrete surface waterproof.
Useful information! Penetrating coating waterproofing is absorbed shallowly into the concrete material, just enough to ensure reliable and effective adhesion to it. This is the main difference between impregnation and coating.
A very important point is that a layer that has such a small thickness must be applied correctly. Otherwise, it will not cope with its functions.
The requirements for modern coating materials that ensure the impermeability of concrete to moisture are very high. It is important to note that in the case of applying a waterproofer from the side that resists the movement of moisture, claims against the material increase. This is due to the fact that it must withstand the pressure of the liquid. This composition must have the following characteristics:
The latter characteristic is very important, since the concrete foundation wears out over time and cracks appear in it. In such situation good remedy coating type must not be damaged.
The waterproofing of concrete can be achieved by another means. It is waterproofing paint. It has many benefits. For example, it is very easy to apply it to the surface yourself, which makes it popular among people.
Depending on the amount of constituent substances that make up such a paint, it can be one-component or two-component. Water-repellent paint is most often one-component paint. This composition is enamel and has high technical characteristics... If desired, it can be used as a joint penetrating waterproofing.
These compositions have a high degree of waterproofing, so they are most often used to protect the walls of swimming pools and other tanks that are constantly in contact with water. Such paint is applied by means of special spray guns. Thus, it becomes possible to independently regulate the jet leaving the tool.
The application of waterproofing material for concrete is carried out strictly in accordance with the instructions. This process is conventionally divided into several stages. Experts do not recommend deviating from them. Of course, it is much easier to use concrete additives for waterproofing, but water insulation is not always made during the construction phase of a building. Let us consider the algorithm of actions, which must be guided by when working with waterproof compositions.
First of all, you should prepare the surface on which the penetrating material will be applied. The surface is thoroughly cleaned, after which it must be degreased. And also it will be necessary to carry out a preventive check of the sewage communication. It should not be damaged in any way.
Useful information! If you want to waterproof a surface that is already many years old, then in this case it may be necessary to remove the old cladding. After that, a layer of plaster is applied. In some situations, it may be necessary to organize a new reinforcement.
Places that match the seams require special attention. They should be punctured carefully. The same applies to wide cracks (more than 4 mm). Finished channels are sealed using special sealing compounds. It is very important not to forget to close the slots at the points corresponding to the passage of the pipes through the wall. For this, sealants are also used.
It is worth noting that for the organization of penetrating waterproofing of the floor, the algorithm of actions will be somewhat different. In this case, the work is simplified, since there is no need for gutting the seams. But in general, both processes are similar to each other, since they imply a thorough preparation of the surface and the application of the most in a convenient way according to the instructions.
The next step is to prepare a solution of penetrating water insulation. In this case, it is necessary to carefully study the instructions, which describe all the dosages and the method of using the mixture. Next, the composition is applied to a previously prepared surface. For this, different tools are used, such as a brush, roller or a special spray gun (depending on the properties of the waterproofing mixture).
Penetrating compounds are modern means that make the foundation waterproof, thereby increasing its service life. These mixes can be very different from each other, but they all do their job better than traditional materials for protecting concrete structures. When choosing a penetrating waterproofing for building foundations, as well as other concrete structures, you need to pay attention to its price, composition and method of application.
During the operation and wear of concrete structures, cracks and other damage are formed in the monolith. The situation is compounded by the influence environment and constant contact with moisture. In order to increase the service life of the building and protect concrete from the negative effects of precipitation and temperature changes, penetrating waterproofing is used during the installation of concrete structures (or after construction), which protects cement surfaces much better than insulating mats and roll roofing felt.
Before choosing a protective penetrating coating for concrete, it is necessary to consider the principle of operation, the pros and cons of this tool.
Penetrating waterproofing for concrete is a material based on Portland cement, which contains special chemical additives (polymers, alkaline earth metals and salts). This solution for protecting concrete from moisture was developed back in 1952 in Denmark, but wide use received recently.
The principle of operation of penetrating waterproofing is as follows: a protective solution applied to a concrete surface penetrates into the cement mass and moves along capillaries filled with water. Due to this, a moisture-proof coating is formed not only on the surface of the monolith, but also inside it. At the same time, the mixture clogs all voids, without violating the vapor permeability of the concrete.
If liquid rubber is used for waterproofing, then this effect will be impossible to achieve. The fact is that coating materials, being applied to a concrete surface (inside of which there is already moisture), form a very dense and non-breathable film on it. Because of this, the so-called greenhouse effect is observed - the moisture inside the concrete is converted into steam, which simply has nowhere to go. As a result, liquid rubber for waterproofing "provokes" the formation of mold on the walls and ceiling of the building. The same disadvantage is possessed by mastic for waterproofing.
If you use a penetrating impregnation for concrete, then its components will react with cement, due to which crystals are formed, displacing vapors to the surface. When no moisture remains in the concrete mass, the growth of crystals stops.
Penetrating waterproofing is capable of filling the concrete thickness by 30-40 cm, while the moisture-proof composition can seal cracks up to 4 mm wide.
The service life of the concrete impregnation is up to 100 years (depending on the manufacturer and the composition of the product). In turn, the coating or rubber mastic retains its properties for no more than 30 years. In addition, the material has many other advantages.
If we talk about the advantages of a penetrating agent for protecting concrete from water, then it is worth highlighting the following advantages:
Nevertheless, such protection of concrete from moisture also has certain disadvantages:
In order for the repair and protection of concrete to be carried out efficiently, it is necessary to choose best material penetrating action.
The most popular today is a mixture of water and Penetron additives. Such waterproofing works more actively with increased concrete moisture. It also increases the frost resistance of a concrete structure up to 400 cycles. Such a penetrating waterproofing of concrete costs from 300 rubles per kg.
Healthy! If the building will be exposed to shrinkage or vibration, it is also recommended to pay attention to the formulations in which latex is present.
To apply a deep penetration waterproofing material, proceed as follows:
Usually, the compositions are applied in 2 layers, 1 cm thick, with a break of 1-1.5 hours. In this case, the material does not need to be rubbed in or smeared.
Knowing how to protect the concrete surface from moisture, you will not only increase the service life of the building, but also increase its frost resistance.
The construction of any home begins with a foundation that needs protection from moisture and groundwater. For this, a number of measures are carried out to waterproof the foundations of houses, using all kinds of roll coatings, mastics, sealants, etc. Such materials must serve as a reliable barrier against water.
Recently, the so-called. What it is and what advantages it has will be discussed in this article.
Most often, roll coatings are used to protect the foundation from moisture. bituminous mastics that require certain knowledge and experience during installation. A small defect in the construction of a protective foundation barrier 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 in basement through concrete walls water seeps out.
The first step is to determine the cause of the leak. The most common reasons are breakout water pipe or poor waterproofing protection. If it is quite simple to eliminate a leak in a pipe, then re-waterproofing the foundation is a very time-consuming and expensive task. To do this, you will have to dig out the entire house around the perimeter, dry out the concrete structure, clean it from dirt, find the place of leakage and then put a patch. True, after a few years, a new leakage site may appear and the whole process will have to be repeated anew.
Therefore, there appeared penetrating waterproofing for concrete and foundations that 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 walls of the foundation are not a serious obstacle to water, therefore, in the absence of good protection, it sooner or later begins to seep into the basement. Water can also seep through cement joints between foundation blocks or through the seams of masonry. The problem of how to fix these leaks after building a house is described a little higher. In such cases, the best solution would be to apply penetrating waterproofing to concrete from the inside or from the living side of the room.
This material is a mixture of high-quality cement with the addition of ground quartz sand and special additives, which perform the main function of waterproofing concrete.
The principle of action of penetrating waterproofing is as follows - when the mixture is applied to the walls of the foundation or to concrete surfaces, chemically active additives begin to penetrate through the capillaries, and upon contact with water, they form insoluble crystals that fill voids, pores, and microcracks. Whereby concrete structures become waterproof, denser, durable and frost-resistant.
If, when protecting concrete, and in particular building foundations 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, active growth of crystals occurs in the pores of concrete.
Penetrating compounds can be applied both from the inside and outside of the structure. Thanks to chemical processes, the concrete itself acquires the property of water resistance. This is the fundamental difference between penetrating waterproofing and other types.
Due to its properties and ease of application, waterproofing of penetrating action has become widespread not only in the construction of houses, but also in the construction of swimming pools, cellars, bathrooms, wells, i.e. for structures exposed to active water exposure.
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 pool, penetrating waterproofing can be added to concrete mix thanks to which the cured concrete will become waterproof. This method is used in the construction of dams, tanks for oil products, berths, bridges, sewers, pumping stations etc. The list goes on and on. As you can see, the use of such compositions is quite wide.
Unfortunately, many people still do not know about this type of waterproofing and use various coatings based on bitumen. The disadvantage of bitumen-containing materials is that when applied from the inside, they cannot withstand the pressure of water, therefore, they cease to perform their function. In addition, with displacement or shrinkage of the soil, the external traditional bitumen protection can receive mechanical damage, which will render the entire foundation waterproofing system unusable.
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, you need to get rid of efflorescence on the concrete surface, which strongly prevent the penetration of the composition deep into the structure.With the mechanical method, you can use a drill or grinder with a stiff metal brush.
A more advanced way is to use water jet machines. high pressure, which quickly and effectively get rid of efflorescence large areas... A protective suit and respirator must be used for this treatment.
At chemical method use special compounds 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. During chemical processing, you will have to spend money on reagents that are not cheap.
2) The second important step is saturation of the treated surface with water. This must be done especially carefully, because the quality of the impregnation depends on how deeply the composition of the penetrating waterproofing penetrates into the concrete. It is necessary that one square meter of the surface absorbs at least 5 liters of water. This should be done in several passes, i.e. spray the surface with a spray bottle, wait until everything is absorbed and repeat the process again.
3) The final step will be to apply the mixture to the surface to be treated. Typically, the application method is written on the packaging with penetrating waterproofing. If there is no such instruction, then the application of the composition takes place in two stages. The first layer is rubbed in 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 a spray gun.
Approximately one hour after applying the finishing coat, the concrete surface must be re-wetted.
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 freezing and thawing cycles increases.
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 arranged as follows:
- on brickwork fastened plaster mesh 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, plaster or lime-based plaster cannot be used. The thickness of the plaster layer must be more than 40 mm;
- in a day, you can apply the composition of the penetrating waterproofing.
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.
Summing up, we will list the main advantages of penetrating waterproofing, which favorably distinguish it from traditional materials:
Now on the market there are materials from various manufacturers. The most common are Penetron, Lakhta, Xypex, Drizoro, Hydrochit, Antihydron, Crystallisol, etc. All penetrating formulations differ slightly in their technical characteristics, application method and price. Therefore, before buying, it is better to consult with specialists from various manufacturers in order to obtain more reliable information.
Penetrating waterproofing is relevant for those who are tired of dampness and want to create comfortable conditions in their home. Many manufacturers offer quality formulations. We invite you to get acquainted with the existing types, leading manufacturers, selection features and application procedure.

If the walls get wet in the assignment and it is decided to carry out reconstruction, the penetrating waterproofing will become optimal choice... The composition is applied to a wet surface, which is not always possible when using other waterproofing materials. In this way, you can form a high-quality hydro-barrier 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, the protection of cellars, bathrooms, walls and one- and multi-storey buildings... The composition is used to protect surfaces exposed to ground, waste, sea water. It is used to process elements of coastal structures, berths, river ports, metro, mines, storage facilities, underground utilities.
After being applied 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 moisture penetration 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 a strong pressure of water.
Attention! The vapor permeability of the base is preserved.
Penetrating action, reducing the permeability of concrete, increases its strength characteristics. As a result, the service life of the building is increased, the appearance of fungus and mold is prevented.
Attention! The composition is capable of penetrating to a depth of 0.4 m.
The formulation suggested by manufacturers may vary. When choosing the right option, consider the features and benefits of each type.
Manufacturers offer not only dry mixes, which should be prepared shortly before application, but also a liquid penetrating mixture for concrete. These formulations are already ready for use. Easy to apply even on uneven prefabricated surfaces using 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, the building structure is made practically invulnerable to water. However, it is rather difficult to ensure uniform protection of the entire surface with this waterproofing material.
According to its characteristics given view similar to impregnation. The coating penetrating waterproofing penetrates into the base relatively shallowly, but at the same time provides effective protection - provided that no mistake was 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 preserve properties when it appears in monolithic base new cracks.
The advantages of this type of waterproofing protection include:
The disadvantages include:
Many manufacturers offer quality products. When choosing a suitable option, you should pay attention to the rating of manufacturers of penetrating waterproofing for concrete:
To purchase the composition, you should consider:
Sweat trademark "Penetron" produces a whole range of penetrating waterproofing for concrete. The material can be used to protect horizontal and vertical substrates. We offer you to get acquainted with the peculiarities of using the composition and the formation of a hydro-barrier.
The cost of waterproofing materials directly depends on the consumption. An average of 0.95 kg of Penetron waterproofing is required for 1 m 2 of the base, if the insulation is applied in two layers. If the surface is uneven or there are a lot of defects, the flow rate increases. For concrete additive "Penetron Admix" consumption per 1m 3 reaches 4 kg.
To prepare a solution with high quality, you should carefully read the instructions attached to the Penetron waterproofing. As a rule, they do it in the following sequence:
To solve the urgent issue of restoring the waterproofing of basements and other long-operated premises of a buried type, traditional bituminous, pasting and plaster waterproofing is used less and less. Outdated materials have been replaced by new technical solutions implemented with penetrating waterproofing.
Penetrating waterproofing compounds include two groups of materials: special surface coatings with a penetrating effect and injection hydroactive solutions.
During the operation of structures, when new contacts of water molecules with concrete appear, a chemical reaction is resumed with the development of compaction deep into the structure.
During contact with water, polyurethane compounds expand in volume. Injection waterproofing spreads throughout the structure. In this case, the water in the cavities is replaced by a waterproof polyurethane filler.
And this video will clearly show how penetrating insulation materials work:
An important advantage of penetrating waterproofing materials is their environmental friendliness. These compounds provide water resistance while maintaining vapor permeability. This property contributes to the preservation performance characteristics building materials - concrete, brick, stone - and the health of people living in such a building.
The advantages of penetrating waterproofing include its ability to form a single whole with the building structure.
The use of penetrating waterproofing has a positive effect on the frost resistance and strength of concrete. This is due to the fact that with constant filtration of water through concrete, the components of the cement stone are washed out. With a loss of 20% calcium hydroxide, concrete loses up to 30% of its original strength. As a rule, such serious consequences are observed during long-term operation - about 40 years. Loss of strength is usually observed - 2-5%. But even such a weakening of concrete can not be eliminated in the depths of the structure by all waterproofing materials. The restoration of the strength characteristics of concrete and reinforced concrete structures contributes to an increase in the frost resistance of the material.
Frost resistance of the waterproofing material itself, in this case, does not matter, since it is a single whole with concrete.
Penetrating waterproofing based on methyl acrylate gel is widely used in foreign countries. This material belongs to injection compositions that penetrate deeply into the thickness of the building material in order to increase its waterproofing characteristics.
The process of using methyl acrylate injection waterproofing is as follows:
An additional advantage of methyl acrylate gel is its ability to penetrate deep into adjacent building structure sites, strengthening and protecting them.
A distinctive feature of this injection material is high speed his actions. When a leak in a basement is closed by means of an injection of gel, the water ceases to seep into the room after a few seconds.
To create a reliable protective layer in the basement, the gel is first injected into the most problematic areas, and then the walls are plastered with a cement-sand mortar with gel additives.
Methyl acrylate gel is used for waterproofing basements and other underground structures, including the subway.
However, penetrating waterproofing compositions based on this gel have a significant disadvantage - the high cost of work. An ordinary consumer cannot do this waterproofing with his own hands, since it will require a special pumping unit... Such equipment is available only in fairly large construction organizations... But, on the other hand, the use of methyl acrylate gel injections will permanently get rid of problems with poor waterproofing.
Penetron produces a wide range of penetrating materials for both waterproofing and injection applications.
Penetron compounds for application to the surface of the protected structure have a number of unique qualities:
The shelf life of waterproofing materials in their original packaging is 18 months.
Penetron is a dry building mixture consisting of special grades of cement, quartz sand of a certain granulometric composition, active chemical additives produced under the company's patent.

The Penetron line of injection waterproofing includes a complex of two-component resins PenesplitSil. It contains two resins: slow- and fast-reacting.
The main purpose of using the injection complex is to stop the flow of water into the cavity of static and moving cracks, thereby protecting the reinforcement from corrosion.
In the case of pressure leaks, PenesplitSil is used in conjunction with PenEpurF.
The waterproofing compound can be used in complexes with perforated hoses located in the seams of the structure during its construction, in brick and stone structures to eliminate capillary suction.
