The plant of waterproofing materials "Penetron" guarantees the compliance of the materials of the Penetron system with the Specifications 5745-001-77921756-2006 "Mixes of dry waterproofing dispersed Penetron systems", as well as all modern standards. The Penetron Waterproofing Materials Factory guarantees that the Penetron system materials contain all components in their respective proportions. The use of Penetron system materials must be carried out in strict accordance with Technological regulations on the use of penetrating waterproofing materials of the Penetron system.

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 used to impregnate the surfaces of concrete, stone and brickwork. As a result of the chemical reaction of a 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.

IN Lately penetrating waterproofing for the protection of foundations, swimming pools, bathrooms, basements and other structures that may be constantly exposed to the harmful effects of moisture, is gaining more and more popularity in the 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 building a foundation, you should take care of it. 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 deeply 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, 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 being 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 saves everything specifications: 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 concrete thickness; protects materials from the effects of salty sea water, groundwater and wastewater with different contents 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 the 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, therefore they are widely used for waterproofing wells, reservoirs with drinking water, swimming pools, bathroom facilities.

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 residential areas: in the bathroom to protect walls and floors from the harmful effects of moisture, in residential areas of the basement, and so on.

Important! Any finishing work should be postponed until the crystallization process takes place. It is possible to apply any types of plaster, including gypsum, or other decorative finishing materials on a surface treated with waterproofing compounds, no 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.

Lakhta 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 you need to save concrete structures with constant harmful effects of ground and waste water, sea water, precipitation.

You can learn more about waterproofing Element from the video.

KT Tron

Well, the last brand that we will talk about is the KT throne. The Kt throne product line is produced in Russia, and it is quite wide. The "family" of building mixtures Kt throne includes:

• Waterproofing mixtures of penetrating action;
• Compositions for the protection of seams and joints of concrete structures;
• Additives that are introduced at the stage of concrete mixing to increase its water resistance, strength, frost resistance;
• Waterproof plasters leveling the surface of the walls;
• Compositions for instant elimination of strong pressure leaks.

Thus, the KT tron ​​group of building mixtures is able to solve any problems associated with the construction and operation of concrete structures. The average cost of 1 kg of dry mix Kt Tron-1, which is used for penetrating waterproofing, is approximately $ 3.5. The area of ​​application of KT tron ​​building mixtures is very extensive: waterproofing of pools, basements, wells, building foundations, bathrooms, walls and floors in residential premises, as well as various objects of industrial and energy complexes. Reviews of professionals about the KT throne line of building mixtures indicate that this is a completely worthy brand. Using KTtron products, it is possible to obtain concrete with high water resistance, corrosion resistance and strength.

You can learn more about waterproofing materials KT throne from the video. Very interesting in this video they talk about the entire product line of the brand.

Penetrating waterproofing (penetrating waterproofing) - materials consisting of Portland cements, fillers and a mixture of chemical compounds (also called active chemical additives). Additives typically include alkali and alkaline earth metal salts, but polymeric additives may also be used.

To protect the foundation, underground part of structures, floors, walls and roofs, there are now several types of waterproofing. The most commonly used waterproofing materials in construction and repair are:

• - rolled roofing material and insulating mats are pasting waterproofing technologies;
• - coating mixtures and painting compositions - cement-sand plaster with the addition of water-repellent modifiers, bituminous mastic, liquid rubber, liquid glass, polymer concrete, synthetic resins, other types;
• — filling technology;
• - cast moisture insulation - special substances are introduced into the concrete (for example, silicate liquid glass) and it acquires special properties;
• - injection waterproofing of deep penetration or it is also called impregnating.

You will be surprised, but penetrating waterproofing was invented almost 70 years ago - in 1952, the Danish company Vandex began producing a fundamentally new insulating material for concrete based on a fine cement-sand mixture for mixing with water. In this case, a liquid composition was obtained, which, after being applied to the surface of the base, not only forms an external protective coating, like coating insulation, but also penetrates into the concrete or stone through cracks, micropores and structural capillaries. At the same time, the mixture turns into durable water-insoluble, clogging all voids, waterproofing microcrystals. Thus, the base materials not only became resistant to water, but also additionally strengthened, which extended their service life.

Figure #1. The principle of operation of penetrating waterproofing

Cheaper types of waterproofing - rolled and coated, have such a drawback that, when applied to a concrete surface with moisture in the pores (and this happens almost always), it forms a dense, non-breathable film that prevents the removal of vapors. Because of this, mold appears on the surface of the walls and floor. Penetrating waterproofing works differently - when a liquid mixture enters the pores of concrete, its components react with cement and the resulting crystals displace vapors to the outside. As soon as all the moisture is bound and the excess is removed, the crystals stop growing and a surface film forms.

Figure #2. Crystals under magnification

Penetrating waterproofing can fill the thickness of concrete 30-40 cm deep, while completely sealing cracks up to 4 mm wide.

The service life of deep penetration protection is from 70 to 100 years (depending on the composition of the mixture). This is almost equal to the service life of the concrete itself! While coating protection is effective for 25-30 years.

Advantages of penetrating insulation

Penetrating waterproofing has a number of advantages that other types do not have. The following should be noted:

• - these materials can be used for all types of buildings and structures, underground and surface structures;
• – the possibility of processing concrete structures of any age, both new and old, during repair and restoration work;
• - deep penetration waterproofing protects reinforced concrete structures from metal corrosion, thereby extending their service life by almost three times;
• - deep penetration mixtures can be applied to wet surfaces, that is, there is no need to pre-dry the concrete;
• - penetrating waterproofing is easy to prepare and easy to apply - manually or by spraying;
• - complete environmental safety for people and environment;
• - as a result of processing the foundation, walls, floor, locations of engineering networks, supports and other concrete structures, a continuous, seamless, completely sealed coating is formed;
• - there is no need for further priming of walls and floors for further finishing;
• - application temperatures - from - 30 to +75 degrees (some mixtures can be operated on hot concrete surfaces - up to 85-105 degrees);
• - the protective film is resistant to mechanical and chemical influences, does not crack, does not peel off during the entire period of operation of the building or structure.

Figure #3. Application of penetrating waterproofing

Applications

Penetrating waterproofing is increasingly used in construction for:

• – processing of foundations of low-rise and multi-storey buildings;
• - protection of walls and floors of basements and basements from groundwater;
• – waterproofing of pools, wells, water tanks, treatment facilities and other water tanks;
• - processing of walls and floors of rooms with high humidity - bathrooms, toilets, laundries, saunas, cellars, etc.;
• — protection of networks of underground communications and facilities;
• - waterproofing of civil defense facilities, mines, storage facilities, metro, tunnels.

Penetrating waterproofing cannot be applied to the following types of building materials:

• - foam concrete and aerated concrete;
• - expanded clay concrete;
• - foam magnesite and gas magnesite;
• - foam and gas gypsum;
• - shungizite concrete;
• - slate-ash concrete;
• - expanded polystyrene concrete;
• - asbestos-cement and other types of large-pore materials.

And the point here is not that penetrating waterproofing is ineffective for these materials, but that due to the presence a large number pores, the consumption of the protective mixture increases tenfold. Therefore, such an application is unjustified from a financial point of view - coating waterproofing is more profitable.

Figure #4. Penetrating waterproofing "PENETRON"

The most effective ready mixes

The following types of compositions are most often used in our country:

1. 1. The most famous penetrating waterproofing is American PENETRON mixtures. They are very effective for new concrete structures and old concrete with cracks no larger than 0.5 mm. To close the cracks more, you must first prepare the surface of the walls and floor with PENECRITE. In the presence of external pressure leaks (wells, pools, treatment facilities), the structure should be treated with a PENELAG hydraulic plug.
2. 2. OSMOSIL - Italian-made deep penetrating insulation, which is used in both private and industrial construction. A feature of the use of this mixture is the mandatory preliminary plastering of the surfaces of walls, floors and structures.
3. 3. Domestic mixtures of HYDROTEX and HYDROCHIT. They are divided into waterproofing materials for external use - marked U, and internal walls and gender - marked B.
4. 4. Very successful in terms of price / quality ratio materials under the brand CRYSTALLIZOL from the domestic manufacturer GidroStroyKomplekt. On sale are different types: for new concrete surfaces - brush W12, for old W12, for joints and seams - "Sutural", for restoration work "Repair", and "Hydroplomba" - for walls of wells.
5. 5. AQUATRON-6 (manufactured by LLC Aquatron - BHK, RF) - a double-acting sealant that penetrates into porous building materials to a depth of 40 cm.

Technology of work with penetrating compounds

Deep penetration waterproofing materials are easy to use. The work is carried out in several stages.

1. 1. Preparation of the surface of walls, floors, structures. This includes cleaning from dirt, drips, dust. Polished concrete should be sandblasted with a solution (1:10) of hydrochloric acid to help open the pores. In the presence of mold, treat the base with an antiseptic.
2. 2. For better adhesion and penetration of the protective mixture, make grooves at the joints and seams at the base, also increase the cracks to a depth of 2.5 cm and a width of 2 cm.
3. 3. For brick walls technology is a little different. Holes should be drilled over the entire surface of the masonry at an angle of 45 degrees, about 2.5-3 cm deep (2/3 of the masonry thickness), with a distance of about 5 cm between them. Rinse these recesses with water under pressure and fill with ordinary plaster mixture (preferably also under pressure). After the plaster has dried, waterproofing can be applied.
4. 4. Moisten the surface to be protected with water – roller or spray.
5. 5. Strictly according to the instructions, dilute the dry composition with water. At the same time, it is not necessary to prepare the entire solution, but a portion that can be worked out in half an hour, and then made a new one (after 30 minutes the composition sets).
6. 6. It can be applied with any tool - roller, brush, spatula (especially at the joints), spray gun. What is better to choose - will be written on the package.
7. 7. It is necessary to apply the composition in two layers with an interval of 1-1.5 hours, up to 1 cm thick, without smearing repeatedly and without rubbing.

Conclusion

Summing up, it can be argued that deep penetration waterproofing has excellent performance properties, is devoid of the disadvantages that roll and coating technology has, reliably protects and strengthens concrete and lasts a very long time. Of the minuses, one can only note the rather high cost of this type of protection.

To solve the urgent issue of restoring the waterproofing of basements and other long-used buried premises, traditional bituminous, pasting and plaster waterproofing is used less and less. Outdated materials have been replaced by new technical solutions implemented with the help of penetrating waterproofing.

The principle of operation of penetrating waterproofing

Penetrating waterproofing compositions include two groups of materials: special surface coatings with a penetrating effect and injection hydroactive solutions.

• The composition of waterproofing coatings includes chemically active additives. Waterproofing compositions spread through the pores and capillaries of concrete with the formation of insoluble crystals.

During the operation of structures, when new contacts of water molecules with concrete occur, a chemical reaction resumes with the development of compaction deep into the structure.

• Hydroactive injection compounds are used to repair leaks in building structures. Basically, these are one-component polyurethane fluids having a low viscosity.

During contact with water, polyurethane compounds expand in volume. There is a spread injection waterproofing throughout the structure. In this case, the water in the cavities is replaced by a waterproof polyurethane filler.

Advantages of penetrating waterproofing

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 of the performance characteristics of 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 the loss of 20% calcium hydroxide, concrete loses up to 30% of its original strength. As a rule, such serious consequences are observed when long-term operation- about 40 years old. Usually there is a loss of strength - 2-5%. But even such a weakening of concrete can be eliminated in the depths of the structure by no means all waterproofing materials. Recovery strength characteristics concrete and reinforced concrete structures increases the frost resistance of the material.

The frost resistance of the waterproofing material itself, at the same time, does not matter, since it is a single whole with concrete.

"Eternal" methyl acrylate injection waterproofing

Penetrating waterproofing based on methyl acrylate gel is widely used in foreign countries. This material refers to injection compounds that penetrate deeply into the thickness of the building material in order to improve its waterproofing characteristics.

The process of applying methyl acrylate injection waterproofing is as follows:

• In problem areas of concrete or brick walls, holes are drilled into which the gel is pumped.
• After being introduced into the building material, the methyl acrylate gel spreads in depth, displacing moisture and clogging the pores. Over time, the gel comes to the outer surface of the structure and completely covers it with a protective dense layer.

An additional advantage of methyl acrylate gel is its ability to penetrate into the depths of areas adjacent to the building structure, strengthening and protecting them.

A distinctive feature of this injection material is its high speed of action. When sealing a leak in the basement with a gel injection, water stops seeping into the room after a few seconds.

To create a reliable protective layer in the basement, first the gel is injected into the most problematic places, 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 compounds based on this gel have a significant disadvantage - the high cost of the work. An ordinary consumer cannot do this waterproofing with his own hands, since a special pumping unit is required for its implementation. Such equipment is available only in fairly large construction organizations. But, on the other hand, the use of injections of methyl acrylate gel will permanently get rid of problems with poor waterproofing.

Waterproofing materials of the Penetron system of surface application

Penetron manufactures a wide range of penetrating materials for both waterproofing and injection applications.

Penetron compositions for application to the surface of a protected structure have a number of unique qualities:

• These compounds are applied to a damp surface that does not require pre-drying, which greatly speeds up and reduces the cost of waterproofing works. Application is carried out with a brush (on smooth surfaces) or a spatula (on uneven surfaces).
• The materials of the Penetron system are easy to work with, you just need to follow the rules described in the instructions.
• These materials can be used both from the inside and from the outside of the structure, regardless of the direction in which the water acts.
• The use of Penetron compositions makes it possible to significantly increase the water resistance grade of concrete, increase the strength and frost resistance characteristics of concrete and reinforced concrete elements.
• In case of mechanical damage to the treated structure, the increased operational properties acquired by it are preserved. The use of compositions of this brand ensures the ability of concrete to "self-healing".
• Processing materials with this system allows you to permanently get rid of the problem of poor waterproofing.
• Concrete coated with Penetron waterproofing layer retains vapor permeability.
• The material can be used both for operated and for structures under construction of all degrees of crack resistance.
• The use of waterproofing compositions of this group makes it possible to prevent corrosive destruction of reinforcement.
• Waterproofing can be used even under conditions of high hydrostatic pressure.
• Characteristics acquired building material Thanks to Penetron processing, they are preserved even under intense radiation exposure.
• Waterproofing compositions of this group are approved for use in drinking water tanks. They are non-toxic, non-combustible materials, explosion and radiation safe.

The shelf life of waterproofing materials in their original packaging is 18 months.

Penetron is a dry building mixture consisting of cement of special grades, quartz sand of a certain granulometric composition, active chemical additives produced under the company's patent.

This waterproofing material has a wide range of applications:

• Processing of monolithic and prefabricated concrete and reinforced concrete structures. It can be used on surfaces covered with cement-sand plaster mortar.
• To cut off capillary suction, Penetron is used in combination with Penekrit. Also, a complex of these materials is used for waterproofing cracks, seams, junctions, joints, and places for entering communications.
• Penetron together with Peneplug or Waterplug is used to combat pressure leaks.

Injection waterproofing system Penetron

The injection waterproofing of the Penetron line includes a complex of two-component resins PeneSplitSeal. It includes two resins: slow and fast.

The main purpose of using the injection complex is to stop the flow of water into the cavity of static and mobile cracks, thereby creating protection for the reinforcement from corrosion.

In case of pressure leaks, PeneSplitSil is used in conjunction with PenePurF.

The waterproofing composition 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.

Features of PeneSplitSeal waterproofing:

• has good interaction with concrete, polymeric materials, metal;
• after polymerization, a highly elastic material is formed;
• does not contain solvents;
• work can be carried out at temperatures (+5)-(+35 0 C), and the operation of treated structures - in the range from (-50 0 C) to (+150 0 C).
