Liquid waterproofing for concrete: technology description, features and reviews

The construction of the house does not last long if the foundation is not protected from moisture. Concrete is the foundation of the foundation, it is distinguished by its durability and durability, but it is not able to undergo a wet environment for a long time. On top of this part of the house is affected by rainfall, while from below - soil and groundwater. Here you should add ground pressure and pressure, chemical reagents that are contained in the water, as well as the temperature difference in the ground and underground parts of the basement.

The need for waterproofing

If the base is not isolated at the time of construction, then in a couple of years it will be necessary to give a much larger amount for the restoration of the material. The waterproofing is presented today in a huge assortment, it can be:

• Mastic;
• Roll;
• Liquid.

The latter variety is more effective, with its help it is possible to create a seamless contour and cut off the path of moisture inside the structure.

Varieties of liquid waterproofing

Liquid waterproofing for concrete is represented by several materials, the most common are liquid rubber and liquid glass. Producers claim only the advantages of these solutions, but in practice it turns out that shortcomings are also present. If the comparison of liquid rubber and glass with roll bituminous materials, as well as membrane films, the first will differ by ease of application on the basis of a variety of shapes. The material is able to penetrate even in hard-to-reach places.

With the help of liquid glass or rubber, it is possible to create a layer that will be more resistant to moisture than bituminous materials.

The technology of waterproofing concrete with liquid glass does not provide for the heating of the material, which facilitates the application and increases the level of fire safety. The resulting layer is non-toxic, it does not swell during heat, nor does it ignite. These materials are able to replace several layers of roll waterproofing, but the application should be done in a rather thin layer, so the final weight is insignificant.

Scope of use

With any surfaces, liquid rubber and glass are able to bond well. These advantages have significantly expanded the scope of the described materials, so today they use waterproofing structures and rooms with constant water availability.

This should include:

• Fonts in the baths;
• Fountains;
• Foundation basins of pools.

Reviews about liquid glass

In construction hypermarkets, in particular in "Leroy", liquid waterproofing of concrete is offered in a wide range. Among other materials it is necessary to allocate liquid glass, which service life is 5 years. This does not mean that at the end of this period, the foundation will be deprived of protection. Glass in the process of exploitation will only gradually self-destruct, and the process will start from the surface layers. According to consumers, for a year the reinforced layer will become thinner by 1 mm. If the liquid glass is applied with a layer of up to 5 mm, then the entire material will lose its properties in the tenth year.

However, users emphasize that waterproofing can provide a longer life, if covered with protective paint. When consumers use liquid penetrating waterproofing for concrete, they emphasize one more nuance, which can be called a minus and a plus. It is expressed in instantaneous crystallization. The solution should be applied very quickly, otherwise it will seize and will not be suitable for work. If you do not have practice, then it is better to entrust the matter to a professional, as the material can simply be spoiled.

Quick setting becomes an advantage, according to buyers, when it is necessary to cover a concrete pool bowl, located close to groundwater. In this case, we are talking about structures that fill up with water in one evening. In wet conditions, waterproofing work can not be carried out with each material, to be exact - only with liquid glass. In 4 hours the surface will dry completely and form an impermeable film.

If you decide to use liquid glass for waterproofing concrete, the instruction must necessarily be read by you. From it you can learn that using this material, it is important to keep the dosage. If you mix the material with the composition by the type of concrete mixture, then there should not be a reinforced dose, since the solution will turn out to be "oak" and will not be adjusted to the design. In this case, the seams will be torn, as well as the joints. In addition, according to consumers, the coating will be unstable to damage, and accidental impact will cause cracks.

Recommendations for the application of liquid glass

Liquid waterproofing for concrete is one of the most effective. If you decide to use liquid glass, then you can apply for application:

• Brush;
• Roller;
• brush.

Depending on what are the final goals, you should choose the proportion of the mixture.

When the overlying layer is planned to cover the web material, the waterproofing becomes superficial. For this, the glass is diluted with concrete and applied with a brush or spray gun in two layers. The mixture will penetrate the foundation by 2 mm, filling the cracks and micropores.

Liquid waterproofing for concrete can also be used when the foundation is prefabricated. In this case, it is required to isolate the joints using a composition of cement and water glass. To create a solid foundation, the liquid glass should be added to the solution. It is important to take into account the dosage, otherwise the strength of the structure will suffer. Filling the foundation must be done by several people who will produce the mixture until it is seized.

Sometimes liquid glass is used for injection waterproofing. In this case, usually work is being carried out to restore the foundation, which began to deteriorate during operation. To do this, in certain parts of the construction holes are made with a perforator, and afterwards the prepared mixture is pumped. It is unlikely that the house has specific equipment, so these jobs are usually trusted professionals, and even with dosage it is easy to overdo it.

Features of applying liquid rubber

Liquid waterproofing for concrete is offered for sale in the form of rubber. It is a ready-made compound, which is applied by roller or brush. Mixtures are cheaper if intended for application in several layers. It should be remembered that after opening the packaging rubber will not be stored, so it must be used immediately. This technology of waterproofing is time consuming and can not provide deep penetration.

You can use a two-component formulation, for example a bitumen emulsion, which is mixed with the polymers when used and applied by spraying. This will require special equipment. The composition is clogged by the force of pressure in the base quite firmly. This allows you to reduce the consumption of material, and if you perform the work by spraying, then you will have to use the services of specialists.

Features of liquid rubber

The price of liquid waterproofing for concrete will be mentioned below. However, the cost is not the only thing you need to know before purchasing a product. Choosing a solution for protecting the foundation, you should pay attention to the characteristics of liquid rubber, which remains elastic even after drying. This indicates that soil motions and shrinkage of the house will not affect the integrity of the formed layer. The material will only stretch a little in those places where the foundation has cracked or it will shrink when displaced. If you compare rubber with liquid glass, the latter does not have such abilities.

Cost of liquid waterproofing

The price of liquid glass for waterproofing concrete is 249 rubles. For 10 liters. This is a 15 kg solution. As for liquid glass, 1 kg of material can be purchased for 155 rubles. The consumption of this waterproofing per one square meter will be approximately 6 kg. Depending on the porosity, the indicator can vary. Sometimes it reaches 3 kg per square meter.

Conclusion

In order to achieve a positive result when waterproofing the foundation with liquid-type materials, it is necessary to familiarize yourself with the technology. For example, liquid rubber should only be applied to a dry surface, but manufacturers claim that the coating will dry out even if the foundation remains wet. And for the material there is no difference - the base was dry or wet; The problem is that the water inside the basement after completing the waterproofing works simply will not find a way out.
