External coating waterproofing for concrete, which one to choose. Penetrating waterproofing waterproofing for concrete: Types and applications. Crystalline waterproofing for concrete

Waterproofing helps resist long-term exposure to moisture by acting as a barrier to water seeping into the pores of concrete. The use of a penetrating composition allows for reliable sealing of a layer up to 15 cm thick. Some manufacturers claim penetration of the mixture into the surface up to 0.6 m. The frost resistance grade increases by 2-3 steps.

The difference between penetrating waterproofing and roll or coating coatings is that during application the components seep through moisture-filled pores to a considerable depth and crystallize. The resulting protection lasts the entire service life of the structure and can only be destroyed together with the base material. The hardened layer will not allow water to pass through, but will remain vapor permeable.

Penetrating insulation involves the use of concrete, reinforced concrete structures and cement plaster. It cannot be chosen for large-porous products: asbestos-cement slabs, foam and expanded clay concrete blocks.

Dry penetrating waterproofing includes the following components:

  1. Portland cement;
  2. finely ground quartz or silicate sand (screening out a given granulometric fraction);
  3. active polymer additives.

Manufacturers try not to disclose full names active chemical additives and indicate in the passport only the main properties that affect compatibility with other materials. In addition to Ceresit and Knauf, they have proven themselves well:

  • Carat;
  • Penetron (Penetron);
  • Vandex;
  • Hydrotex;
  • Xypex,
  • Masterseal;
  • Calmatron;
  • Lakhta.

The products are produced both in ready-to-use form and in the form of concentrates and dry mixtures that require preliminary dilution with water. Packaged liquid waterproofing can be an aqueous suspension (canister), a thicker mastic (closed bucket). Application to a concrete floor is done with a brush or paint roller. The surface must be abundantly moistened with water so that the protection can penetrate to the maximum depth.

Increased efficiency waterproofing works occurs through the use of auxiliary products for a narrower purpose. Sealing of cracks and chips larger than 0.3 mm, protection of joints, seams, passages of technological communications of prefabricated structures is done with a solution with special characteristics from the line of the same manufacturer. Such dry mixtures have a similar composition based on Portland cement, but when hardened in cavities they do not shrink or increase in volume and form a mass with increased strength. The use of a type such as a waterproofing seal is permissible when water comes directly from the destroyed area.

Mandatory characteristics of penetrating capillary waterproofing include obtaining good adhesion of the treated base and increasing the surface's resistance to mechanical stress.

Brands of mixtures for concrete insulation

Penetrating materials are applied like liquid waterproofing, but for the possibility of long-term storage, ease of transportation and use in the right amount they are often released in dry form.

Selected for insulation:

  • foundations;
  • all types of concrete structures;
  • brick inserts into self-leveling or prefabricated reinforced concrete structures;
  • basement walls from being hit groundwater;
  • ceilings and floors;
  • swimming pools, wells, drinking water reservoirs;
  • cement plaster.

WDM SM-Extra is a penetrating coating waterproofing for concrete with water-stopping functions (W16). At the same time, the chemical resistance of the surface increases, additional protection from washing out others polymer additives, improving performance.

Consumption – 1.5 kg/m² with a layer thickness of 1 mm. When performing insulation, apply a layer of 2-3 mm with a spatula or palm. For leveling, use a brush soaked in water. The surface and ambient air temperature should be between +5 and +35°C. A previously used floor is cleaned of dirt and dust, moistened abundantly and maintained in this condition for 5-7 days.

2. KT tron-1.

To waterproof the floor on the ground in a private house located in an area of ​​frequent flooding with groundwater, it is excellent to buy a dry mixture, the use of which is provided in the form of coating and injection. The resulting protection is resistant to man-made pressure of liquid aggressive environments and gases. Concrete becomes immune to sea ​​water, exposure to carbonization and anti-icing salts, vapor permeability is maintained.

The standard consumption for a thickness of 1 mm is 1.2 kg/m². The minimum allowable is 1 kg, recommended by the manufacturer is 1.6. For 1 pass you need to apply no more than 0.8 kg. The frost resistance of concrete increases by F200-F300 (depending on its quality). KT tron-1 crystals can penetrate a liquid medium to a depth of 0.6 m. Concrete treated with penetrating waterproofing can withstand constant exposure to +1,200°C.

3. Penetron.

High-quality floor waterproofing ground floor produced by the penetrating composition of this line. No specific preparation of the work site is required. In a dissolved state, the finished liquid mixture can be applied to a moist or dry surface. This saves time and costs on drying/wetting the base.

In an individual household they choose for the following reasons:

  • applicable for all types of concrete;
  • forms a strong adhesion with reinforcing parts;
  • environmentally safe in contact with drinking water.

4. VODIPREN COMPOUND.

This is an example of a bitumen-latex emulsion with the addition of synthetic resins. It is sprayed simultaneously with the catalyst using a special airless spraying unit. It has a high degree of adhesion and can be used at -25 and +100°C. Polymer rubber can withstand impacts and stretching up to 5000%. The advantage is versatility - can be used on surfaces made from different materials(concrete, brick, wood, metal, plastic, glass). Can be painted and does not form seams, completely sealing the base.

To protect against moisture, take as an additive liquid glass(sodium) GOST 13078-81, more about it in. It is chosen when bitumen coating is not possible both for covering the base and for adding to a fresh solution. It is valued for its low cost of material and good characteristics strength of the resulting surface, antibacterial properties. But liquid glass is not used on its own, only as an additive. Re-processing occurs at least every 5 years.

6. Penecrit.

To seal seams from the inside, mixtures (dry) Penecrit are produced, which are used in combination with Penetron. They are waterproof W14 with a flow rate of 1.5 kg/m.p.

7. Gidrotex-Sh.

It has a frost resistance of 200 cycles and a consumption of 0.9-1.0 kg/m.p.

Materials for penetrating protection should be purchased based on the following fundamental points:

  1. Availability of application technology, surface preparation requirements.
  2. Compliance with the maximum permissible indicators of operating conditions ( temperature regime, expected loads, aggressiveness of the environment).
  3. Estimated service life. Concrete structures are designed, as a rule, to last for decades - the high cost of protection will be repaid many times over by the absence of the need for repair and restoration work.
  4. Compatible with other materials and their components. To guarantee the quality of the result, all penetrating compounds (basic and additional) must be taken from the same line. When choosing a penetrating impregnation, it is better to take into account the type of plasticizers in concrete and the chemistry of the intended finishing coating environment.
  5. Shelf life. Quick setting of a solution (for example, liquid glass) requires working skills and calculation of preparing portions of the mixture for one-time production. The alternative is to increase the number of workers.
  6. Shelf life of dry packaging before the start of work.

When carrying out repairs or restoration of concrete or plaster coatings, penetrating concrete waterproofing is used. This material helps improve quality characteristics concrete and makes it moisture resistant. We’ll look at how to choose where to buy penetrating concrete waterproofing below.

Penetrating waterproofing of concrete: features and characteristics

Penetrating waterproofing is a material that contains Portland cement, fillers and active chemical additives. The additives are salt elements of alkalis, alkaline earth metals or polymers.

main feature penetrating waterproofing is based on the principle of the solution: chemical additives applied to the surface penetrate deep into the concrete, moving through capillary pores filled with water.

The function of protection against moisture consists in the interaction of calcium compounds, which are the main component of cement, with penetrating waterproofing additives, while the pores that are located on the cement surface are reduced and do not allow water to pass through.

The scope of application of penetrating waterproofing extends to:

  • repair and waterproofing of concrete surfaces;
  • restoration of reinforced concrete structures;
  • restoration of cement-sand coatings.

In addition, the use of penetrating waterproofing is associated with waterproofing:

  • concrete or brick basements;
  • cellars;
  • foundations;
  • swimming pools;
  • terraces;
  • garages;
  • inspection holes;
  • civil defense objects;
  • water containers;
  • wells.

Elements whose main components are foam concrete, expanded clay concrete and other types of porous concrete and asbestos-cement materials are unsuitable for applying penetrating waterproofing.

The main difference between penetrating waterproofing and rolled materials is that the waterproofing acts over the entire area and thickness concrete structure, A rolled materials protect concrete only in the place of their installation. In addition, rolled materials are not able to withstand constant contact with water, so their installation in swimming pools and water tanks is ineffective. Penetrating waterproofing has an unlimited lifespan and performs its functions until it collapses. concrete covering.

Limitations in the use of concrete waterproofing

The use of penetrating waterproofing is becoming a fairly popular process, but there are cases when, due to ignorance or lack of experience, these materials are used in cases where their use is inappropriate. Therefore, we propose to consider cases in which concrete waterproofing is necessary.

The use of penetrating compounds comes down to their use as one of several options for waterproofing or the main waterproofing material.

In the process of waterproofing foundations that are constantly in contact with water, the use of waterproofing roll type is not always effective. To further enhance the waterproofing characteristics of this type of structure, it is recommended to use penetrating waterproofing, which can provide internal protection from exposure to moisture.

The fundamental difference between penetrating waterproofing and its alternative options is its ability to penetrate the thickness of concrete. Some types of penetrating solutions are capable of waterproofing concrete up to a depth of forty centimeters.

It is recommended to use penetrating waterproofing materials to protect structures made of concrete or reinforced concrete, to waterproof surfaces that are constantly in contact with moisture, in the process of waterproofing foundations, if the groundwater level is too high.

Main advantages of purchasing waterproofing materials penetrating action:

  • increasing the water-repellent characteristics of concrete structures;
  • formation of a durable waterproofing layer over the entire thickness of the concrete product;
  • the ability to work on internal and external parts of the structure;
  • Possibility of application on wet surfaces;
  • no need to dry the concrete.

The main advantage of purchasing penetrating materials is their ability to protect the interior of the structure from external moisture. This explains the widespread use of this material when carrying out restoration work on premises, such as basements, in which there is no possibility of carrying out external waterproofing.

In addition to a large number of advantages, penetrating waterproofing is characterized by the following disadvantages:

  • concrete structures that have or are subject to the formation of surface cracks will not be protected from moisture, therefore the use of penetrating waterproofing is associated only with crack-resistant structures;
  • provides only superficial protection for brick buildings, since the brick does not contain the substances necessary for the reaction;
  • not suitable for waterproofing porous concrete bases;
  • not applied to foundation blocks.

Operating principle of concrete additive for waterproofing

First of all, the waterproofing mixture is mixed with water and covers the wet surface concrete base. The waterproofing effect occurs due to the fact that the pores of the concrete are gradually filled with waterproofing solution.

Due to the fact that the material contains a large number of active chemical additives, they begin to interact with the elements in the concrete composition, resulting in a crystallization process, and a continuous barrier is created that makes the concrete moisture resistant.

The process of compacting the concrete solution occurs due to the presence of water. If there is no water in the solution, the process stops; if water is present, it resumes.

The penetration of waterproofing into concrete reaches thirty to forty centimeters. The presence of micropores, capillaries and microcracks filled with crystals increases the water resistance of concrete several times. In conclusion this process a concrete base is obtained in the form of a compacted waterproof coating.

Penetrating waterproofing is rightfully considered a unique material, since during the processing of concrete, with the help of these solutions, interaction occurs between chemically active substances and cement stone. As a result, an insoluble thread-like crystal coating is formed, which is resistant not only to moisture, but also to aggressive substances.

Structures that have been treated with penetrating waterproofing are resistant to chemical reagents, aggressive irritants, saline solutions, waste water and other aggressive components, from environment.

The use of penetrating waterproofing has a positive effect on the frost resistance of concrete, provides its protection from wind, mechanical shock, and precipitation and prevents the process of oxidation of reinforced concrete reinforcement sections.

Crystalline compounds are characterized by the presence of tiny pores through which water does not pass, but at the same time the concrete does not lose its air or vapor permeability characteristics. Thus, the concrete coating “breathes” but does not allow moisture to pass through.

Moisture is required to form crystalline compounds on the surface of concrete, so perfect option for penetrating waterproofing materials to work - a newly installed concrete base. When working with dry concrete, it requires preliminary moistening.

In addition, among the main advantages of penetrating waterproofing there are:

  • compaction of the concrete structure;
  • compaction of cracks up to four millimeters;
  • no need to treat the concrete base with a primer;
  • resistance to puncture, tearing or separation from the surface;
  • no need for protection during backfilling.

The most effective is the use of penetrating waterproofing at a temperature of use of concrete structures from -30 to +10 degrees.

The use of penetrating waterproofing protects concrete from chemical exposure, chlorides, from metal corrosion. At the same time, concrete is not exposed to moisture and ultraviolet radiation. Also, penetrating materials have good resistance, are resistant to stress, compressive strength and resistance to radiation.

Penetrating waterproofing of concrete: materials, selection process

Before you buy penetrating waterproofing for concrete, you should read the recommendations that will help you choose correct view solution suitable for a specific stage of the waterproofing process.

The use of cement-based penetrating waterproofing is important when processing external walls, floors, basements, foundations, liquid storage tanks, sewage systems, tanks, tunnels, mines, wells, parking lots, technical buildings, water dams, swimming pools.

We propose to consider the main manufacturers of penetrating waterproofing products:

1. "Osmosil" - Italian penetrating waterproofing. The material looks like ready mix which is based on the use of osmotic waterproofing cement, with high strength protective composition and with special filling admixtures.

The use of "Osmosil" is associated with carrying out internal and external waterproofing work on the foundation and foundations of the building. It is recommended to use the material in the premises of mines, elevators, and when arranging drainage system and water tanks, when renovating a shower or bathroom. Application of the material is possible both from the inside and from outside. "Osmosil" is applied to stone, concrete or brick bases. The main feature is preliminary plastering of the surface. It is not recommended to use waterproofing on surfaces that are subject to constant shrinkage or vibration. In this case, it is recommended to add latex-based additives to the solution. The coating treated with this waterproofing material is recommended to be used in temperature range from -35 to +85 degrees. Waterproofing work is carried out at temperatures above five degrees Celsius. The finished coating is subjected to load no earlier than after two days.

2. "Hydrotex" - penetrating waterproofing, which includes sand, cement and penetrating additives. There are two types of this waterproofing: "Hydrotex" B - used for internal waterproofing, "Hydrotex" U - for external waterproofing.

Scope of application of the material:

  • concrete and stone structures;
  • concrete buried or semi-buried foundations;
  • basements, garages;
  • storage;
  • tunnels, mines;
  • sewer, water systems;
  • swimming pools, water tanks, etc.

The developers of Hydrotex products claim that their materials are capable of penetrating concrete to a thickness of up to one meter. "Hydrotex" is not used on stone-concrete structures, which are characterized by the absence of capillaries.

Features of the use of penetrating waterproofing

1. Basements.

Protecting the basement from moisture accumulation involves not only the use of good waterproofing, but also the correct construction of the walls and their support in the form of a foundation. The positive effect of penetrating waterproofing will be achieved if there is a minimum number of joints on the walls, materials will be introduced directly into concrete mortar, and the application will be both internal and external.

2. Potato storage facilities.

If you do not provide protection from moisture at this facility, it will fill with water and the potatoes will spoil. Therefore, to ensure high-quality waterproofing of potato storage facilities, it is necessary to use special concrete plates, which have waterproofing characteristics or take care of organizing waterproofing using special materials water protection.

The use of dry mixtures helps prevent the formation of a film on the coating, since they are used directly in the solution itself and act along the entire perimeter of the concrete. The use of dry mixtures is the most the best option waterproofing of such structures. The main advantage of such waterproofing is that there is no need to dry the surface before application. The mixture is applied to the wet coating.

This waterproofing is applied with a brush and immediately interacts with the surface of the concrete. In addition, the solution helps fill microcracks, while the wall does not allow moisture to pass through, but allows air to pass through.

3. Foundation.

Foundation waterproofing is a necessary part of building a home. Since it is the foundation that is most susceptible to environmental influences. Therefore, this part of the building requires protection from the effects of melt and ground water, as well as from harmful substances, falling from groundwater. At the same time, penetrating materials are absolutely harmless to people, but very effective for the building. It is recommended to use such waterproofing in the construction of buildings for any purpose, from public and industrial to private and social. Since the building has been in use for decades, even if the groundwater level is low during the construction of its foundation, after a certain time, changes are possible that, if the waterproofing is poor, will significantly affect the entire building and lead to its destruction.

4. Wells.

The use of penetrating waterproofing when carrying out work to improve the water-repellent characteristics of concrete in a well allows you to start work without preparing the surface, and there is no need to scrape the walls, moisten the concrete or maintain the waterproofing.

IN Lately quite often there are cases when penetrating materials are used as the main waterproofing element, which WRONG.

Penetrating compounds can be used as one of the elements in the chain of system waterproofing materials, but not as the main one. These materials are convenient to use, effective when a new structure (basement, underground garage, etc.) has leaked, but consider them as universal remedy for all occasions - WRONG, 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 the plaster and degrease it, opening access to the capillary system. And simple iron brush This cannot be done - you need to clean it 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 actively in 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), it is recommended to carry out waterproofing from penetrating materials with inside protected structures (basements).

Penetrating waterproofing- cement-sand mixture using chemical additives.

Fundamental difference penetrating compounds from all other materials - 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 concrete and reinforced concrete structures;
  • waterproofing of foundations and basements actively in contact with water;
  • in combination with surface waterproofing of the foundation with high level groundwater.

Advantages

  • increasing the water resistance of concrete structures (and ONLY! concrete);
  • formation of a waterproofing layer in the concrete mass;
  • possibility of processing external and internal surfaces structures, 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 moisture penetration from the outside. That's why this type waterproofing found wide application during the reconstruction of basements and semi-basements, when external waterproofing is no longer possible.

FLAWS

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

The combination of penetrating waterproofing on stable bases and elastic waterproofing on bases subject to deformation can solve many waterproofing problems during 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 waterproofing effect is achieved by filling the capillary-porous structure of concrete with insoluble crystals.

Active chemical additives included in the material, penetrating into the concrete, enter into a chemical reaction with the components concrete mixture, forming insoluble compounds (crystals) that create a continuous barrier that prevents the flow 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 of active chemical components into the concrete body can reach tens of centimeters. Micropores, capillaries and microcracks up to 0.3-0.4 mm wide (diameter), filled with products chemical reactions, increase the water resistance of concrete by 2-3 steps.

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

Construction wooden house includes protecting it from the harmful effects of moisture. Moreover, it is necessary to protect not only the walls, foundation and roof, but also floors, ceilings and any elements. Penetrating waterproofing of concrete can play an important role, especially in spring time floods About what penetrating waterproofing of concrete is, how it is used in wooden house construction and what reviews about existing trains sound from users, we will find out by reading this article.

Penetrating concrete waterproofing or penetration was invented in Denmark and came to us relatively recently. The first composition was called Vandex and was released by VANDEX. Later, based on this invention, the Canadian Xeyplex from the company XYPEX, the Spanish Dreizero from DRIZORO, and the American Penetron from PENETRON appeared.

Judging by user reviews, American Deep Action Penetron is the best of the entire listed line. It more reliably protects concrete from cracking and moisture penetration. But there is a big disadvantage - Penetron is expensive.

Our manufacturing companies have solved this problem by developing their own deep-acting penetrating compositions: Aquatron, Lakhta, Coral, Kalmatron, Gidrotex, Wesson, etc. Among the most popular are Lakhta. Lakhta and Penetron are similar in composition, but the price for the domestic composition is lower.

Reviews about Lakhta are mostly positive. negative ones are associated with low-quality counterfeits, or with working with compounds that have expired. In some stores you can find deep-acting formulations Lakhta and Penetron with good timing shelf life, but the composition was not stored correctly. It is difficult to insure against such purchases. By purchasing high-quality penetrating waterproofing, you can endow concrete with unique protective properties.

Penetration action

IN wooden house penetrating waterproofing is used to protect concrete foundation surfaces, basement and basement walls, garages and wells.
Any concrete structure has a porous structure. Moisture easily gets into the smallest cracks, and as it rises it penetrates into the wood. But there is no need to talk about the interaction between water and wood again.

The use of roll waterproofing materials does not provide a long-term effect. Delamination occurs and the foundation deforms and cracks. And bituminous coating compounds are labor-intensive to apply. 90% of them must be heated and applied quickly, as hardening occurs within a few minutes. Moreover, such events are not safe.

Deep penetrating waterproofing helps solve most problems. The main thing is to choose the right composition and carry out the processing in a comprehensive manner. The main action of concrete penetrating compounds is based on the chemical interaction of free lime (calcium hydroxide) and capillary water inside the concrete. Due to the reaction of these elements, hydrosilicates and hydroluminates are formed, which are practically insoluble in water. These crystals form a strong protection within the structure of the concrete structure and enhance the texture of the material. Apply waterproofing with a simple brush or roller; to simplify it, you can use a spray gun. The composition penetrates the structure concrete wall by 10-20 cm.

Pros and cons of penetrating coatings

For a wooden house I use penetrating compounds for protection basement, foundation, roof. But the scope of use of the composition is almost limitless; it can be used to treat walls, floor joists, rafter system. You can work with the material inside the house and outside. Positive reviews about waterproofing are associated with its main advantages:

  1. Waterproofing with a layer of 10 cm in 1 pass.
  2. Healing of microcracks in concrete structures.
  3. The frost resistance of concrete structures increases 2-3 times.
  4. Resistance to chemical influences.
  5. The service life of the impregnating concrete protection is more than 25 years.
  6. The structure remains vapor-permeable, which means the circulation of oxygen in the wooden house is not disrupted.
  7. Can be applied from the inside and outside of the building at any temperature.

Over time, the effect of waterproofing only becomes stronger. And it can be applied to any surface, dry or wet.
Negative reviews are mainly about the high price of the material.

Features of applying concrete waterproofing

Apply penetrating emulsions to concrete surface walls and floor of the basement need the following steps:

Depending on the type of work, waterproofing measures using penetrating emulsions may vary.

Injections for concrete or brick parts of the house

A wooden structure, for example a log house, can be built on columnar foundation. It can be assembled from red brick. Previously, penetrating compounds were not used for waterproofing such structures; the situation has changed in the last 5 years. Any brickwork is treated in the same way.
Processing is carried out in two ways:

  1. Penetrating concrete cut-off waterproofing. In increments of 25 cm, shallow holes are drilled in the masonry at an angle of 45 °. A protective emulsion will be injected into them with a special syringe.
  2. Waterproofing “flat jacket”. The brick is cut down in parts and some of the seams are cut. Instead, plaster is applied mixed with a penetrating compound, and the compound is once again driven on top.

Important: All work in the brick part of the foundation can only be carried out with a special device. Therefore, specialists carry out the work. Applying the composition to a brick foundation with a brush or roller is not effective.
The main thing for work is to choose an effective and high-quality composition.

MK-TRON penetrating

The relatively young MK-Tron brand has already established itself in the market of waterproofing materials with stable product quality at a relatively low cost. In particular, the brand produces dry mortar: MK-Tron penetrating. Similarly, the waterproofing result occurs due to the filling of the pores and microvoids of concrete with a sparingly soluble composition in liquid form on a wet surface, which subsequently crystallizes.

The limitation of the penetration depth of MK-Tron is determined by the pore depth of the concrete to which the composition is applied. After treating a concrete structure with a solution, water resistance increases by 2-3 steps, frost resistance increases by F200. The consumption of the penetrating composition is calculated at approximately 1 kg of dry mixture per 1 m2 of concrete surface. Packaging - convenient plastic buckets with a handle for packing 5kg and 25kg.

The table below shows the main parameters of the MK-Tron penetrating mixture:

Filler fraction, mm, no more 0,63
Consumption per 1 m² when applying a layer 1 mm thick, kg 1,2
Consumption per 1 m², minimum, kg 1,0

Lakhta or Penetron, pros and cons

Mixtures of Russian-made Lakhta and American Penetron can be purchased in the form of a dry composition with a grayish color. The composition contains quartz sand and special cement - Portland.
Lakhta and Penetron are used:

  1. For installation of cut-off waterproofing.
  2. In brick and stone laying.
  3. Pool protection.
  4. For treating floors, ceilings and concrete foundation walls.

Performs a protective function against: water, oils, alkalis, acids, and other liquid substances. Lakhta and Penetron have a unique property: the crystals formed inside the foundation will increase when moisture enters, but in a dry state the size does not change. This allows the protective layer to adapt to varying degrees of humidity. Penetration depth: Lakhta - 13 cm, Penetron - 15 cm.

You can buy the mixture at various construction stores or on the Internet. It is sold in weights of 5, 10, 20 kg. The price of the compositions differs by 200-500 rubles.

Advantages of Lakhta and Penetron waterproofing:

  1. Non-toxic and do not cause an allergic reaction.
  2. Tolerates any water pressure.
  3. They adapt to the structure of the foundation and become one.
  4. Do not block the access of oxygen through the foundation.
  5. When it enters a structure, it increases frost resistance and strength of the foundation.
  6. Can be used in any climate zone.

Penetrating waterproofing for concrete- this is a set of measures that prevent the ingress of water, as well as protect the structure from the effects of aggressive environments. Waterproofing work helps to avoid corrosion, wall destruction, dampness and mold. They are carried out during the construction of concrete structures - foundations, basements, floors, walls, swimming pools, underground garages and tunnels. Also, these works can be carried out at the stage of sealing seams, joints, and ceilings.

Penetrating waterproofing products are available in powder or ready-made solution. The basis of any mixture, as a rule, is cement and fine quartz sand. The compositions of the mixtures differ due to various modifiers and fillers.

Penetrating mechanism

Active additives penetrate into microcracks in concrete (water repellents) to a depth of 10 to 60 cm and enter into a chemical reaction with it. At the end of the process, crystals are formed that are stronger than concrete. The crystals of the waterproofing solution do not dissolve back with water. A durable waterproof coating appears on the outside.

Double benefit

Thus, the waterproofing solution performs a double function: it clogs pores and uneven areas inside and forms a protective layer on the outside. These properties are especially beneficial for the reconstruction and restoration of concrete walls.
When water disappears, the chemical reaction stops. The next time water hits the surface, the crystallization process resumes in depth. Thus, the crystals become an integral part of the concrete structure. The degree of penetration of active substances depends on the density of the concrete, its humidity and the ambient temperature.
As a result of the use of funds penetrating waterproofing You get a coating that will become harder every day.

Pros of penetrating waterproofing

More details

    Treatment with penetrating compounds significantly increases the frost resistance and water resistance of building structures, while the strength characteristics practically do not increase.

    Penetrating waterproofing is insensitive to damage to the outer layer, since the waterproofing properties are distributed throughout the depth and volume of the concrete.

    The porous structure of concrete stone acquires waterproof properties, but at the same time continues to remain vapor permeable (breathable)

    The classic composition of penetrating waterproofing includes only environmentally friendly mineral components.

    The waterproof crystalline structure formed in the pores of the cement stone is practically inseparable from it and continues to function throughout the entire life of the building structure.

    Penetrating waterproofing is a volumetric material that is applied to the surface of concrete, but at the same time ensures the formation of a waterproof crystalline structure in the entire available volume of the material, which is actually limited by the dimensions of the porous system of the concrete stone and the initial supply of chemically active substances.

    The material can be used under positive and negative hydrostatic pressure and applied to both the outer and inner surfaces of the structure being treated

Disadvantages of penetrating waterproofing

More details

    Penetrating waterproofing is used only for materials based on cement binder (concrete, reinforced concrete, plaster and other construction mixtures). This is due to the fact that the components of cement stone are the basis for the formation of a crystalline structure in the pores of concrete, which provides high waterproof characteristics.

    Penetrating waterproofing is not used to prevent water from entering through technological, including cold, seams, as well as concrete cracks, because the process of germination of a crystalline structure can only develop within a single, connected system of pores. Special suture materials are used to waterproof seams and technological openings.

    Penetrating waterproofing does not prevent water from entering through newly formed cracks, incl. shrinkage and structural defects of building structures. Therefore, when carrying out work on external waterproofing of buildings and structures, the use of penetrating compounds is recommended in combination with elastic waterproofing materials.

    Penetrating waterproofing does not work effectively in porous cement-containing materials with compressive strength characteristics less than 150 MPa.

Instructions for use (abstract) of penetrating waterproofing:

The information is intended to familiarize you with the general principles of using penetrating waterproofing.
When carrying out work, you must follow the instructions placed directly on the packaging of the material used, as well as in the corresponding section of our website.
More details

Surface preparation:

  1. The material is used exclusively for processing concrete or other bases made on the basis of a cement binder, because the presence of calcium is a prerequisite for the formation of a waterproofing crystalline structure.
  2. During preparation, it is necessary to ensure maximum opening of the pores on the treated surface and its abundant moisture, since the presence of water molecules is another prerequisite for the formation of a waterproofing crystalline structure, and its growth and development occurs directly in the pores of the concrete stone. The presence of pollution of various natures is unacceptable.
  3. The material is not intended for waterproofing seams and cracks with an opening of more than 0.4 mm, therefore, to prevent the entry of water, these defects must be reliably waterproofed in advance with suture or repair materials.

Preparation of penetrating waterproofing.

  1. Only clean drinking water is used, because... the presence of foreign impurities of organic and inorganic origin has a harmful effect on the course of chemical processes in modern multicomponent compositions and significantly reduces the final water resistance of the building structure.
  2. Care should be taken to fulfill the requirements for intermediate holding of the solution, aimed at ensuring better dissolution of, as a rule, a small amount of modifying or chemically active components, initially in dry form, and achieving uniform distribution throughout the entire volume of the solution.
  3. It is prohibited to add water to the solution in excess of the technological norm, because the presence of excess water leads not only to a decrease in the ease of application of the solution, but also to a serious deterioration in the technical characteristics of the material. Please note that the consistency of the solution changes significantly during mixing and until all additives are completely dissolved it may look quite hard.
  4. If the temperature of the mixing water significantly deviates from the norm, an imbalance occurs in all time parameters of mixing and hardening of the solution, which should be taken into account when applying the material and carrying out further work.

Applying a penetrating waterproofing solution:

The requirements when applying the solution are related to ensuring the most active interaction of the chemically active part of the solution with the surface being treated.
  1. The solution should be in close contact with the base over the entire area of ​​the treated surface.
  2. The thickness of the working layer must be uniform and correspond to the material consumption rate.
  3. The "swelling" areas are cleaned and re-processed without fail.

Care of the treated surface.

  1. The treated surface must be kept moist for three days to ensure diffusion of the active components of the composition into the thickness of the treated surface and maintain the dynamics of the primary formation of a waterproofing crystalline structure.
  2. The holding time of the material before applying subsequent layers is, in general, 28 days, but can be significantly less. in this case, it is indicated by the manufacturer in the instructions for use located on the product packaging.
  3. In the case of germination of a crystalline structure on the outer side of the waterproofing coating, before applying subsequent layers, it must be mechanically removed, and the surface itself must be treated with a weak acid solution to stop the crystallization process.
