Penetrating waterproofing for concrete: the best way to protect against moisture
Penetrating waterproofing for concrete is a mixture that is used to protect foundations and other parts of a building from moisture. It is used in both private and industrial construction. The composition of such a mixture includes cement, sand, as well as various chemical components. The depth of penetration of active substances into the concrete is 10-12 cm. This allows you to reliably protect the foundation from moisture and extend its operational life.
Penetrating waterproofing to protect concrete: the principle of operation
Concrete blocks that are part of the foundation are exposed to moisture throughout the entire operation. Precipitation contributes to the erosion of the base of the building, which can lead to serious consequences. Concrete has microcracks, through which moisture penetrates, getting into the basement.
It is also worth noting that water passes not only through microscopic cracks in the structure of concrete, but also through seams that are located between individual structural elements. These places are vulnerable and also need reliable protection. Brickwork does not have independent resistance to moisture.
In order to ensure the protection of the foundation or any other structure (for example, a garage floor made of cement), it is customary to use penetrating waterproofing for concrete. It is most often applied at the construction stage of the house. But in the case when the house is already built and there is a problem with moisture in the basement, then waterproofing is applied from the inside.
The principle of operation of the protective composition is simple and clear. After its application to concrete, the process of absorption of chemical additives through microcracks begins. In case of contact with water, the mixture that has filled the capillaries of the block crystallizes. Such crystals fill the empty space and prevent the subsequent penetration of moisture. It is important to note that they do not dissolve in water.
Useful information! In addition to waterproof qualities, such impregnation strengthens the concrete material, makes it more durable and wear-resistant.
To apply such a mixture, a wet surface is necessary, which distinguishes it from rolled coatings and bitumen-based mastics. Before you buy penetrating waterproofing for concrete, you should clearly understand the principle of its operation.
Penetrating mixtures protect the foundation not only from the effects of moisture, but also from the appearance of mold and fungi. The process, which is based on the interaction of free lime and moisture, allows you to reliably close the pores in the concrete structure and protect the structure from destructive factors.
In what cases is waterproofing used for concrete?
To speed up the process of penetration of waterproofing substances into the concrete material, it is necessary to apply the composition on a wet surface. This method is very popular in cases when it is necessary to reconstruct the premises. Often penetrating compounds are used when there is no possibility to apply another method of protection.
Penetrating substances are actively exploited to protect the foundations of private residential buildings from moisture. Industrial buildings are also included in the list of objects that are treated with waterproofing of this type. Objects may be exposed to high humidity:
- swimming pools;
This waterproofing material for concrete is not very popular, as some people simply do not know about its existence. However, the application of bitumen mastics is accompanied by certain difficulties, since they harden very quickly. In turn, rolled materials do not guarantee one hundred percent protection of concrete from the destructive effects of moisture.
It is worth noting that penetrating mixtures are recommended to be used for blockage of microporous material. This means that for buildings made of foam blocks, such a tool is not suitable.
The main characteristics of penetrating waterproofing for the foundation
Waterproofing of any structure can be carried out at the construction stage. Moreover, many experts recommend using this method. It takes into account the addition of a dry substance to the cement mortar. Such a mixture affects the structure of the future foundation, the waterproofing properties of which are manifested from the very beginning.
Additives in concrete for waterproofing contribute to the protection of the foundation from the effects of precipitation and water in the ground at all points without exception. The operational life of this insulation will be equal to the shelf life of the foundation itself, since they are a single whole.
Pay attention! Crystals that form in microscopic pores are resistant to water. They can be destroyed by passing water, but even in this case, their recovery occurs over time. Regeneration of this type allows for a high degree of foundation protection.
Advantages of penetrating waterproofing for the foundation
An important advantage of such additives is their ability to speed up the process of building a house. This is due to the fact that their use eliminates the need for drying concrete. Thus, time is saved due to penetrating waterproofing for concrete. Reviews of such compositions are mostly positive.
When applying the mixture to a concrete surface, it is necessary to know that it must be wet. Moreover, the higher this indicator, the faster the crystallization reaction occurs inside the pores. The material itself does not lose its properties after processing, retaining all useful technical characteristics, such as:
- vapor tightness;
- resistance to temperature fluctuations;
The only indicator that is subject to change after applying waterproofing is water resistance. Such insulation is the most acceptable solution in the case when it is necessary to protect the foundation of a ready-made structure from moisture. This is due to the fact that it eliminates the need to excavate the foundation. You can buy waterproofing for concrete in a specialized store or place an order online.
The penetrating composition provides reliable waterproofing protection, regardless of which side it was applied to the foundation. The pressure of groundwater in this case also has no effect on the quality of protection. The insulated surface, as well as all seams and butt points, become immune not only to moisture, but also to an aggressive environment with different Ph values.
Penetrating waterproofing for concrete: disadvantages
Any of the currently existing insulation has some disadvantages. The high characteristics of penetrating compounds make them the most suitable for protecting foundations and other structures, but they are not ideal. The main disadvantage of such mixtures is that they are recommended to be used in combination with other waterproof products. For example, to protect the foundation seams from moisture, it is recommended to purchase a special substance designed for this.
Another disadvantage of penetrating water insulation is that it is quite expensive. Depending on the brand and specialization of the mixture, the price of concrete waterproofing can vary from 50 to 350 rubles per 1 kg.
Pay attention! As a rule, this type of insulation is sold in bags weighing 25 kg.
Before starting work on applying such a composition to the surface, preliminary preparation must be carried out. It is very important to clean the wall so that no (even minimal) dirt remains on it. Otherwise, the composition will not be well absorbed into the material. And it is also worth degreasing the surface in advance. Experts recommend using a garden hose to clean the wall, since the water coming out of it under pressure copes with this task very well.
The cost of waterproofing material can vary greatly depending on its variety and brand. The most economical and reliable option is the penetrating waterproofing of Lakhta. You can buy such a mixture for a very reasonable price (80-100 rubles per 1 kg).
All of the above manipulations are necessary in order to provide free access to microscopic pores. If there are large cracks and cracks in the concrete walls, they need to be eliminated. It is recommended to cover up such defects with cement mortar. This option is the most acceptable and simplest.
It is also worth noting that waterproofing mixtures of this type do not work if they are used to protect the surface of brickwork. With their help, you can only protect and strengthen the seams in such a structure. Thus, it is better to use more common and familiar protection options for brickwork.
Nevertheless, taking into account all the disadvantages, there is currently no more effective means for waterproofing concrete structures. Before buying this composition, it is recommended to study the companies that are engaged in its production. This will allow you to choose the most reliable tool for a very reasonable price.
Waterproofing of penetrating action: an overview of popular brands
Currently, the construction market is replete with various materials designed to protect the foundation. Penetrating insulation for concrete is also no exception. It is implemented by different companies, each of which has its pros and cons. Experts do not recommend buying the cheapest formulations, as they are often not of high quality.
The average price range is the most acceptable, since it includes good, high-quality brands of compounds. When choosing the necessary means, you should consult with the seller. And also before you buy a penetrating waterproofing, it would be useful to study reviews about it on the Internet. To date , the following brands of penetrating mixtures are the most common and effective:
The first option is the most common. It has been used for about half a century around the world. Lakhta is distinguished by a variety of choices. A mixture of the Kalmatron brand is considered the most versatile penetrating waterproofing. Pools, wells, cellars and balconies – all these structures can be protected using the products of this manufacturer. There are many other brands that differ in their composition, application and action. However, the above companies have proven themselves best in the production of products for the protection of concrete structures.
Penetrating waterproofing Penetron: characteristics
Penetron brand building compounds are used not only for private, but also for industrial purposes. These mixtures appeared quite a long time ago, and the effectiveness of their use has been time-tested. The composition of this mixture includes sand (quartz) and active chemical compounds.
The cost of such a penetrating composition is quite high – 250-300 rubles per 1 kg. However, its technical characteristics fully justify such a price. Penetrating waterproofing Penetron allows you to protect not only the foundation, but also walls, as well as floors made of concrete. The Penetron consumption is quite simple to calculate, since about 1 kg of composition is required to protect 1 m2.
Pay attention! Be vigilant, as domestic markets are filled with various kinds of fakes, which can cost much cheaper than the original. The quality of such mixtures is questionable, so you should not save on waterproofing the foundation and other concrete structures.
Penetrating waterproofing for concrete Penetron is used to protect wells, swimming pools, floors and walls in bathrooms and garages from water. Before using such a composition, it is advisable to read the instructions and watch a training video in which all the nuances of the work will be described in detail.
Waterproofing of the foundation with rolled materials
Performing waterproofing works on the foundation with rolled materials of various types: detailed instructions.
Features of penetrating waterproofing Lakhta
The Lakhta brand is domestic, and its distinctive feature is a wide range of dry mixes used for waterproofing concrete. The products of this brand are used for various tasks, including to strengthen the water resistance of seams.
The principle of operation of such mixtures is the same as in the case of the waterproofing material Penetron. The active chemical components penetrate into the pores of the concrete structure and crystallize when interacting with water. Before you start applying the waterproofing of the Lakhta, it is necessary to prepare the concrete surface.
The cost of this mixture is lower than the previous composition, but the products have pretty good reviews. The price for 1 kg of the substance is approximately 120-180 rubles. According to the technical characteristics, such insulation is practically in no way inferior to the composition of Penetron. The price of penetrating waterproofing Lakhta determines its popularity and prevalence in the construction market.
This mixture is used to protect concrete structures of industrial and domestic significance from moisture. With the help of such waterproofing, it is possible to strengthen the water resistance of walls and floors in a cellar or garage. And it is also actively used to protect swimming pools, bathrooms and balconies.
Kalmatron penetrating waterproofing: price and properties
The composition of this brand allows you to quickly and effectively eliminate small leaks that destroy the foundation of the building. This mixture helps to strengthen the surface strength of the concrete material. The peculiarity of the waterproofing substance Kalmatron is its versatility. Compositions of this type are used to insulate the following materials from moisture:
- reinforced concrete;
- foam concrete;
- aerated concrete.
The price of penetrating waterproofing for concrete of this brand is the most attractive of all the brands presented. The cost of 1 kg of product is about 80-100 rubles. Thus, for a bag with a volume of 25 kg, you will need to pay approximately 2000-2500 rubles. Such compositions can be used both in the construction process and during the operation of concrete structures. Domestic consumers note quite good water-insulating properties of Kalmatron compounds.
Useful information! Before purchasing this waterproofing material, one important point must be taken into account. It is not recommended to use it if the Ph level at the facility is in the range from 3 to 11.
Liquid waterproofing for concrete: characteristics
In addition to dry mixes, there are other ways to protect concrete structures from the harmful effects of moisture. One of them is the use of liquid waterproofing. Today, you can find a variety of liquid materials of this type in composition, but the following are the most common:
- liquid rubber;
- liquid glass.
These materials have both advantages and disadvantages. Before purchasing one of them, it is recommended to study the features of their use. Liquid products are much easier to work with, especially when compared with bitumen mastics, membrane films and rolled products.
You can buy liquid waterproofing for concrete at the construction market, in a store or on the Internet. The cost of such formulations is about 2 times higher when compared with dry mixtures. Liquid substances that ensure the water resistance of concrete are also convenient because they can be applied to an uneven surface.
Nuances of using liquid waterproofing for concrete
The process of applying the protective composition is quite simple. It does not involve heating the mixture, as in the case of bitumen mastic. It is also worth noting that the quality of waterproofing of this type is very high. Among other advantages of the liquid mixture, it can be distinguished that it does not cause any harm to human health, since it does not emit active chemical compounds.
Liquid water insulation is resistant to high temperatures, so in the summer you should not be afraid that it will start to melt. This material is an excellent alternative to roll and other insulators.
Liquid glass for waterproofing concrete is applied using the following tools: a brush, a construction roller. The viscosity of the composition resembles the density of PVA glue. Such a mixture is applied in a thin layer, which after drying requires additional protection. This is due to the fact that the finished layer has a weak resistance to mechanical influences.
Penetrating insulation of this type allows you to achieve excellent results. Impregnations based on dry mixtures increase water resistance, and liquid compositions make the concrete structure practically invulnerable to water. But this method has some disadvantages. For example, it is quite difficult to make a layer of the required thickness with your own hands. Therefore, it is better to use the services of a professional.
Characteristics of coating waterproofing for concrete
Many people confuse impregnation with coating insulation. This is not surprising, since they are very similar in their properties. Both of these types of waterproofing must be applied to the surface of the structure, after which they penetrate through microcracks deep into the concrete. The difference between the impregnation and the coating mixture is that it protects the concrete from moisture, penetrating quite deep into the blocks. In turn, the coating mixture makes only the concrete surface waterproof.
Useful information! Penetrating coating waterproofing is absorbed into the concrete material shallowly, just enough to ensure reliable and effective adhesion to it. This is the main difference between impregnation and coating.
A very important point is that the interlayer, which has such a small thickness, must be applied correctly. Otherwise, it will not cope with its functions.
The requirements for modern coating materials that ensure the impermeability of concrete to moisture are very high. It is important to note that in the case of applying a waterproofing agent from the side that resists the movement of moisture, claims to the material increase. This is due to the fact that it must resist the pressure of the liquid. This composition should have the following characteristics:
- good adhesion;
- resistant to water;
The latter characteristic is very important, since the concrete foundation wears out over time and cracks appear in it. In such a situation, a good coating agent should not be damaged.
Features of waterproofing paint for concrete
The waterproofness of concrete can be achieved with the help of another means. It is a waterproofing paint. It has many advantages. For example, it is very easy to apply it to the surface yourself, which causes its popularity among people.
Depending on the amount of constituent substances that make up such a paint, it can be one-component or two-component. The paint, which has a water-repellent effect, is most often one-component. This composition is enamel and has high technical characteristics. If desired, it can be used as a suture penetrating waterproofing.
These compounds have a high degree of waterproofing, so they are most often used to protect the walls of swimming pools and other reservoirs that are constantly in contact with water. The application of such paint is carried out by means of special spray guns. Thus, it becomes possible to independently regulate the jet coming out of the tool.
Features of concrete waterproofing application
The application of waterproofing material for concrete is carried out strictly in accordance with the instructions. This process is conditionally divided into several stages. Experts do not recommend departing from them. Of course, it is much easier to use additives in concrete for waterproofing, but water insulation is not always produced at the construction stage of the building. Let’s consider the algorithm of actions that you need to focus on when working with waterproof compounds.
First of all, it is necessary to prepare the surface on which the penetrating material will be applied. The surface is thoroughly cleaned, after which it needs to be degreased. And it will also be necessary to carry out a preventive check of the sewage communication. It should not have any damage.
Useful information! If you want to waterproofing a surface that is already many years old, then in this case it may be necessary to remove the old cladding. After that, a layer of plaster is applied. In some situations, it may be necessary to organize a new reinforcement.
The places that correspond to the seams require special attention. They should be carefully crushed. The same applies to wide cracks (more than 4 mm). The finished channels are sealed using special sealing compounds. It is very important not to forget to close the cracks at the points corresponding to the passage of pipes through the wall. Sealants are also used for this.
It is worth noting that for the organization of penetrating waterproofing of the floor, the algorithm of actions will be somewhat different. In this case, the work is simplified, since there is no need for stitching seams. But in general, both processes are similar to each other, since they imply careful preparation of the surface and application of the composition in the most convenient way in accordance with the instructions.
At the next stage, it will be necessary to prepare a solution of penetrating water insulation. At the same time, it is necessary to carefully study the instructions, which describe all the dosages and the method of application of the mixture. Next, the composition is applied to a pre-prepared surface. To do this, different tools are used, such as a brush, roller or a special spray gun (depending on the properties of the waterproofing mixture).
Penetrating compounds are modern means that make the foundation waterproof, thereby increasing its service life. Such mixtures may differ greatly from each other, but they all cope with their task better than traditional materials for the protection of concrete structures. When choosing penetrating waterproofing for building foundations, as well as other concrete structures, it is necessary to pay attention to its price, composition and method of application.
