Penetron: instructions for use, work procedure

The deep penetration composition Penetron is used for waterproofing the thickness of concrete, reinforced concrete structures and cement-sand plaster layers of a grade of at least M150. It is applied to thoroughly moistened surfaces that have been previously cleaned of materials that would prevent the penetration of Penetron components into concrete. The use of impregnation significantly increases the water resistance of concrete, and also eliminates defects and microcracks with an opening width of up to 0.4 mm. Can be used on any side of the structure, regardless of the direction of water pressure.

Impregnation to reduce water permeability of concrete and porous surfaces

Preparing the concrete surface before using the Penetron system

Clean the concrete surface from dust, dirt, oil products, cement laitance, efflorescence, shotcrete, plaster layer, tiles, paint and other materials that prevent the penetration of active chemical components of the Penetron system materials.

Clean concrete surfaces using a high-pressure water jet or other suitable mechanical method (for example, a wire brush). Treat smooth and polished surfaces with a weak acid solution and rinse with water for an hour. Remove excess water formed on the horizontal surface after using a high-pressure vault jetting unit using a special vacuum cleaner.

Before applying penetrating waterproofing, the surface must be thoroughly moistened: the process will go faster with enough water

Along the entire length of cracks, seams, joints, interfaces, abutments and around the communications entry, make U-shaped fines with a cross-section of at least 25x25 mm. Clean the fines with a brush with metal bristles. Remove the loose layer of concrete (if any).

Use a jackhammer to cut cavities of pressure leaks to a width of at least 25 mm and a depth of at least 50 mm with an expansion inward (if possible in the shape of a “dovetail”). Clean the internal leak cavity from loose, peeling concrete.

Attention! Before applying Penetron system materials, it is necessary to thoroughly moisten the concrete until the concrete structure is completely saturated with water.

Components of Penetron and their action

Penetron contains the following components:

high grade Portland cement with certain properties;
quartz sand;
chemical components for the solution that are used to modify the mixture. During contact with concrete, these components seep in through the pores and form insoluble crystals.

Such crystals begin to fill all the spaces found to block the path of water molecules. But at the same time, the base retains the ability to “breathe”, that is, air and steam continue to circulate even through obstacles . In this way, Penetron blocks access to dampness and water molecules, and the service life of building materials increases.

You won't need too much Penetron to get the job done, but the containment ball should be sufficient, particularly to keep basements and foundations out of water. When bonded with insulating material, concrete becomes stone and provides maximum protection.

The concrete base, coated with Penetron, turns into a durable coating about 3 mm thick. It will not be damaged even under strong pressure , so you don’t have to worry about water penetrating into the base of building materials.

Preparation of PENETRON composition

Mix the dry mixture with water in the following proportion:

400 grams of water per 1 kg of Penetron material
1 part water to 2 parts Penetron material by volume.

Pour water into the dry mixture (not vice versa).

Add water to the dry mixture. Not the other way around

Mix for 1-2 minutes by hand or using a low-speed drill. The type of prepared mixture is a liquid, creamy solution. Prepare a quantity of solution that can be used within 30 minutes. During use, stir the solution regularly to maintain the original consistency.

Mix with a drill at low speed

Attention! Re-adding water to the solution is not allowed.

Advantages and disadvantages

This type of waterproofing impregnation is often used by builders when constructing foundations and other structures where the effects of moisture may be most noticeable. The popularity of Penetron waterproofing is due to the following positive characteristics:

Long period of operation. It is enough to use the coating composition once to protect the concrete structure forever.
Penetrating waterproofing can be applied where there is minimal free space. For example, if the foundation is being processed, there is no need to completely excavate the foundation.
Waterproofing of this type does not affect the basic qualities of concrete.

Penetrating waterproofing significantly increases the resistance of concrete to moisture, but reliable sealing of objects can only be achieved in combination with other materials. For example, in places where communications enter a building, as well as when connecting vertical and horizontal planes, water penetration into a room located below ground level is possible even when using waterproofing of this type.

The disadvantages of this material also include its high cost. Compared to traditional materials that are used to protect concrete from moisture, costs can be several times higher.

Waterproofing of concrete elements and structures

Attention! Thoroughly moisten the surface before applying Penetron system materials.

Use the Penetron material to eliminate and prevent capillary filtration of water through vertical and horizontal (including ceiling) concrete surfaces.

After preparing the surface, apply a solution of the Penetron material in two layers with a synthetic fiber brush or using a mortar pump with a spray nozzle. Apply the first layer of Penetron material to wet concrete. Apply the second layer on top of the fresh but already set first layer.

Apply the composition with a brush with synthetic bristles

Before applying the second layer, moisten the surface.

Attention! The application of the Penetron material solution should be carried out evenly over the entire surface, without gaps.

The consumption of Penetron material in terms of dry mixture when applied in two layers ranges from 0.8 kg/m2 to 1.1 kg/m2. An increase in the consumption of Penetron material from 0.8 kg/m2 to 1.1 kg/m2 is possible on uneven surfaces with significant cavities or potholes.

Attention! All cracks, joints, seams, junctions, service entries should be insulated using Penecrit material. If there are pressure leaks, use Peneplag or Waterplug material.

The mechanism of action of penetrating waterproofing "Penetron"

Composition of liquid waterproofing for concrete

Artificial stone made from cement composite is known for its high strength and durability. However, the material has a weak point - moisture. The structure of concrete is porous and cracks appear over time. These places are filled with moisture, which destroys the connecting chains between the components. And seasonal temperature changes cause an increase in voids.

The best solution to the unwanted effects of water exposure is concrete penetrating waterproofing. Rolled and coating materials create a separate barrier that fails, among other things, from mechanical loads from the outside. Means capable of penetrating the structure of the monolith become part of it. Thus, the durability of protection is calculated over a noticeably longer period of time.

In addition to the beneficial properties of the hydrobarrier, the advantages include the composition of the material. Its basic component is Portland cement. This point is important, since compositions identical in binder are characterized by good compatibility and high adhesion. Mechanical resistance is provided by quartz filler, and active chemical additives are responsible for the rest. In Russia, a single standard was approved for the production of protective equipment in 2015: GOST R 56703.

Waterproofing brick and stone walls

When waterproofing structural elements made of brick or stone, the surface must be plastered and treated with a solution of the Penetron material. The following conditions must be met:

Plastering should be done with a cement-sand mortar of a grade not lower than M150. The use of lime mortars and gypsum plaster is unacceptable.
Plastering should only be done using a masonry mesh (mesh size 50×50 mm or 100×100 mm) firmly fixed to the surface. The gap between the masonry mesh and the brick base must be at least 15 mm.
The thickness of the plaster layer must be at least 40 mm.
The structure of the plaster layer should be dense, without air gaps. It is recommended to carry out plastering continuously to avoid the formation of a large number of working seams.
Leave plastered surfaces for at least 24 hours before applying the Penetron material (according to the requirements for plastered surfaces).

Brick walls and walls made of foam concrete are coated with impregnation after plastering

The consumption of Penetron material in terms of dry mixture when applying two layers is 0.8 kg/sq.m.

Attention! Insulate all cracks, joints, seams, junctions, service entries using Penecrit, pressure leaks with Peneplag or Waterplug materials.

Modern construction teams very often turn to waterproofing for help. It is produced in the form of a dry building composition consisting of a specialized albolite, quartz sand with particles of a certain diameter, with a chemical admixture of modified elements. Its main purpose is to waterproof the surface of a concrete and reinforced concrete structure being built. Thanks to Penetron, the building is not afraid of moisture and exposure to water, and its strength and frost resistance increases. And chemical additives, in turn, provide active resistance in case of ingress of alkali, acid, sewage and groundwater, as well as if there is contact with sea water. The article will focus on penetrating waterproofing "Penetron"

How to care for surfaces treated with Penetron

Scope of application of Penetron waterproofing

"Penetron" can be used as a stand-alone insulation or used in combination with auxiliary mixtures of the same series. It all depends on the type of construction.
Such waterproofing is carried out when the surface has cracks 0.4 mm wide, and if they are larger, it is necessary to additionally use Penecrit. Thanks to the combined use of these compositions, it is possible to remove capillary suction (if the waterproofing is damaged), get rid of cracks, wide seams and joints, mating and abutting. And in order to eliminate pressure leaks, Penetron is used in combination with Peneplag and Waterplug.

The main advantage of such a mixture is its environmental and radioactive purity. That is, after carrying out all the required checks, Penetron showed that it is absolutely harmless to the environment and to people. It has a certificate indicating that it can be freely used in construction, as well as for creating domestic and drinking water supplies.
During its development, such a property as a rigid barrier to moisture was obtained. That is, concrete blocks will not allow water to pass through them, even at high hydrostatic pressure. Penetron is also used to protect concrete from aggressive environments (acids, water with high salt levels, wastewater, etc.).

Advantages of Penetron

The mixture itself does not lose its warranty period. The duration of its operation is directly related to the base that was treated with it. And since it imparts additional waterproofing properties, this design will last even longer.

Convenient application technology. Due to its penetrating properties, it can only be applied on one side. In addition, Penetron waterproofing does not require mandatory drying of concrete.
It has, in fact, a unique property - self-healing. That is, if cleavages, micropores or other similar damage (with a diameter and depth of up to 0.05 cm) are formed in a concrete block, the growth of crystals is initiated, which fill the entire space. This happens the moment the solution comes into contact with water.
"Penetron" increases the level of water resistance of the structure. This indicator is designated by the letter W. After applying waterproofing, within a month the indicator increases from 4 to 10, and if you wait 3 months, the concrete block will have an indicator of 20W.
The composition only affects contact with moisture, otherwise the concrete retains its original characteristics. Impregnating waterproofing does not in any way affect the vapor permeability of concrete structures.

Advice: there are fakes of the original brand on the market, so before buying Penetron waterproofing, it is recommended to ask for quality certificates.

Operating principle of penetrating waterproofing "Penetron"

The waterproofing is diluted to the required consistency, after which it is applied to the moistened concrete surface. For the best effect, it is necessary that the concrete surface is as wet as possible.
The chemically active components of Penetron, penetrating deep into the concrete, react to the presence of ionic compounds of calcium and aluminum, metal oxides and salts, which are part of the composition of the concrete mixture. After which, upon interaction with liquid, crystalline hydrates are formed, which no longer dissolve. It is a network of such formations that fights concrete defects, forming one whole with the concrete structure.

At the site of filled cracks and pores, surface tension forces of liquids act, as a result of which water simply does not move.

The rate at which crystals form and how deeply they penetrate into the concrete structure depends on several factors:

concrete density;
concrete porosity;
humidity and temperature values of the environment.

The main component on which the stopping or construction of such chemical crystals directly depends is water. If it is there, then the process continues, but if it is absent, it stops.

Properties of penetrating waterproofing "Penetron"

Since Penetron works with a wet surface, costs that would otherwise be spent on drying concrete are significantly saved.
Application of this waterproofing does not require any specific skills or abilities. The sequence of actions is described in the instructions on the package.
It does not matter on which side the concrete base will be covered with Penetron - from the outside or from the inside. It will act the same in both cases.
Concrete treated with this waterproofing will increase its characteristics in terms of water resistance, strength and frost resistance. At the same time, the design retains its old parameters for vapor permeability.
If for any reason the surface is damaged, this will not affect its acquired waterproofing properties.
Concrete with “Penetron” acquires a new property – “self-healing”.
This material does not wash out over time.

If you use an additional additive of the same system of materials, for example “Penetron Admix”, then the surfaces will not be at all afraid of exposure to aggressive environments.
For such waterproofing, it does not matter what brand of concrete you have to deal with. In addition, protection extends not only to the concrete itself, but also to its reinforcing components.
"Penetron" is an environmentally friendly material, which is why it is often used to build drinking water tanks.

How to properly prepare the surface?

Before applying the solution, the concrete surface must be clean. Therefore, it is cleaned of any contaminants - sand, dust, gunite. To do this, you can use special installations that supply a stream of water under high pressure. Or manually using a wire brush. If there is a paint coating, it must also be removed.
When the concrete has a smooth and even surface, all remaining fatty deposits can be removed with a weak acid solution left for an hour. Then rinse with water.
It should be remembered that Penetron waterproofing only works with a damp surface, and the moisture must saturate the entire structure of the concrete.

Formula for preparing the Penetron mixture

In order to create a high-quality mixture, you should adhere to the following proportion: 1 kg of waterproofing goes to 0.4 liters of water.
To ensure proper mixing of the consistency, water must be poured into the dry mixture, and not vice versa. Mix the substance with your hands or a drill for 1–2 minutes. Ultimately, the waterproofing should be liquid, similar in thickness to sour cream.

Experts recommend preparing the amount of solution that can be applied within half an hour. And when finished, prepare more mixtures. To prevent Penetron from thickening, it is stirred from time to time during operation.

If the waterproofing thickens, under no circumstances should it be re-diluted with water. It is necessary to re-prepare a “fresh” composition.

Waterproofing "Penetron" technology

After the structural elements have been cleaned of dirt and the mixture has been prepared in the required quantity, you can begin the processing process itself.
To do this, you need to have a brush made of synthetic fibers or a sprayer. Waterproofing is applied to the surface in two layers.
As already mentioned, work is carried out only with wet concrete. Therefore, the first layer is applied immediately after the surface has been moistened. And they give some time for the composition to “grab” with the concrete. After which they immediately begin the second layer, but before that the surface is again moistened with water.

It is important to ensure that both layers evenly cover the structure and do not leave any gaps or gaps. The average consumption of dry mixture for smooth surfaces will be 0.8–1.1 kg/m2, and if there are significant irregularities, this figure will increase.
If pores, seams, joints are detected, as well as at the junction of block structures, it is necessary to apply “Penecrete”, which isolates them. But in case of a leak - “Peneplug” or “Ventirplag”.

Waterproofing "Penetron" of technological openings and pressure leaks

When building houses, panel formwork is used in foundations and walls. They, in turn, leave behind gaps that should also be eliminated. “Penetron” and “Penecritus” can serve just for this purpose.

The first step is to remove the plastic sleeve, which can be done using a drill. Next, the resulting hole is cleaned of dust.

After which, using polyurethane foam, the gap is filled, but it is important that the edges remain free on both sides by about 2–2.5 cm. The walls of the resulting cavities are moistened with water, after which the hole is filled with “Penecrete”. The mixture is applied with a spatula or by hand. But in the second case, you should remember your safety and protect your hands with gloves. The solution itself should “sit” tightly in the cavity.
After “Penecrete” is in its place, “Penetron” is applied on top of it, using a brush, at a rate of 1 kg per cubic meter. For the right effect, two layers are used.
In a similar way, places where there is a leak are eliminated. Only in this case mixtures of Peneplag and Waterplag are used. They are pressed tightly into the hole where the leak is coming from. These materials have a high degree of adhesion. The speed of adhesion of the material to the surface of the hole is largely influenced by the temperature of the water and concrete - the lower it is, the slower the process.
If the leak leaks through vertical cracks, then work is carried out in the direction from top to bottom.
The resulting patches are treated with Penetron on top, but professional builders do not need additional protection. But such savings are not always advisable, since the price of Penetron waterproofing is low, on average it is 300 rubles / kg.

Application of penetrating waterproofing on brick and stone surfaces

“Penetron” is inherently a rather unique waterproofing product. It works not only with concrete, but also with brick and stone. But in the case of such an application, some features should be taken into account.

Initially, the working surface must be plastered. For this purpose, only those cement-sand mortars are suitable that have a grade of at least M150 and in no case should you use gypsum plaster or lime mortar.
Initially, a masonry mesh with a cell size of 50x50 mm or 100x100 mm is fixed to the surface. The plaster layer is applied no thinner than 4 cm, so that no air gaps remain.
Plastering is recommended to be done at one time.
The prepared surface is allowed to dry for a day, after which it can be worked with with Penetron. The consumption of Penetron waterproofing is 0.8 kg/m2.

How to care for surfaces treated with Penetron

It is important to ensure that the treated concrete is protected from mechanical damage for 3 days. Also, surfaces should not be allowed to dry out prematurely, as this will lead to peeling and cracking. To avoid this problem, you can use the following methods:

spraying with water. A spray bottle or spray gun is suitable for this;
cover the entire surface with plastic wrap.

Often concrete structures are lined with finishing materials. This work can be carried out no earlier than 28 days after treatment with Penetron.

Care of the treated surface

Protect treated surfaces from mechanical influences and negative temperatures for 3 days. Make sure that the treated surfaces remain damp for 3 days; there should be no cracking or peeling of the coating.

The following methods are usually used for moistening: water spraying, covering the concrete surface with plastic film.

When caring for a surface treated from the water pressure side, it is recommended to increase the moistening period to 14 days.

The composition gradually penetrates deep into the concrete. Approximately 90 cm

Advantages of Penetron waterproofing

Looking at the price tag of this waterproofing, the average buyer will think, weighing the arguments for and against. Indeed, Penetron cannot be called cheap. You can pay 300 rubles for 1 kg of this material only if you are fully confident that it will reliably protect the foundation from water.

In order for your choice to be informed and correct, let’s see what the manufacturers promise us:

Unlike coating and adhesive waterproofing, Penetron is not afraid of mechanical influences. Its service life is equal to the service life of concrete (up to 100 years).
The use of this type of waterproofing does not require pre-drying of the concrete.
The structure can be processed from any side (the foundation does not need to be dug up).
This composition has the property of self-liquidation of through cracks that appear on a concrete structure during operation (opening no more than 0.5 mm). Water entering these cavities activates the growth of cement stone crystals and they close the crack.
In 3 months, Penetron increases the water resistance of concrete to the maximum grade W20 (water does not penetrate its structure even under a pressure of 2 MPa).
Waterproofing does not impair the physical parameters of concrete: mobility, strength and setting time. At the same time, concrete completely retains its vapor permeability.

Application of decorative coating

It is recommended to apply painting and finishing materials to the surfaces of structures treated with Penetron system materials after 28 days. The holding time can be reduced or increased depending on the requirements of a particular type of finishing material for the maximum permissible moisture content of concrete.

Attention! Before applying a decorative coating, surfaces treated with Penetron system materials must be cleaned mechanically to improve adhesion using a high-pressure water jet (for materials applied to wet concrete) or a brush with metal bristles (for materials applied to a dry concrete surface).

Application of Penecrit solution

Work must be carried out at a temperature not lower than +5 degrees. 2 hours after applying the composition, the groove must be filled manually using a screw mortar pump or a spatula. The thickness of the layer at one time should not be more than 30 millimeters. If you have to work with deeper grooves, then the mixture is applied in several stages. As an alternative solution, you can fill the mixture with finely washed crushed stone, the size of which varies from 5 to 10 millimeters. Its volume can be 50 percent of the volume of the composition itself. After 2 hours, it is necessary to apply a certain amount of water to the groove and adjacent areas, and then treat everything with the Penetron mixture. The consumption of the Penecrit dry mixture when cutting the dimensions described is 1.5 kilograms per linear meter.

Operating principle of penetrating waterproofing

The liquid insulation solution is applied only to the wet concrete surface. By interacting with the base material, the mixture creates a high chemical potential while maintaining a lower potential of the internal structure of concrete. The resulting osmotic pressure promotes the penetration of Penetron deep into the material of the insulated structure.

The higher its humidity, the faster and more efficiently this process will occur. Waterproofing components are capable of penetrating several tens of centimeters into concrete structures.

Penetron is a leader in the production of waterproofing systems

Penetron is a world-famous company specializing in the production of waterproofing systems that have no analogues. Well, the formula for a substance that protects concrete from the destructive effects of negative environmental factors still remains a mystery. Therefore, it is almost impossible to create something similar.

So, the line that flaunts its glory includes the following products:

“Penetron” is a product that protects a structure from water penetration;
“Penebar” is a raw material used for sealing flaws in underground buildings and places where utility lines pass;
“ Penecrete” is a composition intended for treating joints, seams, cracks, etc.;
"Peneplug" - a mixture used to eliminate leaks;
“Penetron Admixa” is an additive to concrete that self-heals cracks that form;
“Waterplug” is a composition used to eliminate leaks.

Construction mixtures used in the markets of 92 countries have been tested by leading experts in the world and have all certificates confirming their high quality assessment.

Reviews about "Penetron"

“It is very important that the concrete is of high quality and that the time between pours is observed. The effect of waterproofing with the Penetron mixture will largely depend on this.”
“In all my time in construction, this material has never failed. It is important to have a competent waterproofing engineer.”
“I work with Penetron products myself and communicate a lot with other builders. I can say with confidence that it works, but the main thing is to read the technical specifications well, use this product correctly, and not indulge in gags.”

Features of the additive Penetron Admix

Penetron helps increase the water resistance of concrete, in addition, it removes microcracks and defects. Application is allowed on all sides of structures, regardless of the direction of fluid pressure.

Waterproofing systems are divided into two categories : primary - it is determined using the characteristics of the supporting structure. Secondary waterproofing, which is applied to this structure during waterproofing work and during repairs.

In primary waterproofing, water resistance is determined by the following characteristics:

concrete;
construction material.

The denser the concrete, the less porous it is, and its water resistance is higher. Water resistance can be increased in different ways, in particular, by introducing additives into concrete at the stage of its production; in this case, the number and diameter of capillaries and the thickness of the cavities in it are reduced in concrete.

Penetron Admix is a dry additive that is added to the concrete mixture. With its help, the water resistance of concrete structures is increased by filling the pores with crystalline formations, and the concrete is able to independently “heal” small cracks.

In an aqueous environment, the active components of Penetron Admix enter into a chemical reaction with ionic complexes based on aluminum and calcium, as well as with salts and oxides that are found in concrete.

Technical characteristics of Penetron Admix

With the help of this composition, the waterproof grade of concrete increases after treatment. In addition, the frost resistance of the material increases . Penetron can also be used for drinking liquid reservoirs.

Penetron Admix is the primary form of material protection; it helps eliminate waterproofing of the material after reaching the required strength.

Its use according to the instructions is allowed together with other additives that are often used in concreting, for example, anti-frost and plasticizing.
