Materials for waterproofing concrete. for injection,

Concrete, despite the high strength characteristics, needs protection from moisture. He, of course, does not have as pronounced hydrophobicity as wood, but over time, the water is still able to settle in the pores of its structure, giving rise to destructive processes. In this article we will look at the most popular and effective methods of waterproofing a cement surface in order to guarantee a long operational life.

Methods of waterproofing

Various waterproofers differ in their composition and method of application. They can be, as used for treating an already frozen surface, or for adding to the kneaded solution. But let's move on to more specific options.

Injection

This is a very innovative method, which, as the name suggests, consists in introducing a gel-like substance into the concrete structure, where it is transformed into a waterproof, tight membrane.

It has several important advantages:

1. Very high efficiency. Prevents any penetration of fluid for many years.
2. Wide range of applications. It makes it possible to cope even with gushing leaks, and not only with increased dampness.
3. Versatility. Application is possible not only to concrete, but also to such porous materials as brick, artificial foam concrete or real stone.

1. Strengthening the strength characteristics of the processed object.
2. Easy to use do-it-yourself. WITHам процесс несложно осуществить во время заливки, после неё, и в процессе реставрационных работ.

There are also some drawbacks:

1. High price. You need to pay for quality results, but you will be sure of it.
2. The need for special equipment, including a high-pressure pump.

WITHовет: есть смысл приобретать необходимое оснащение в том случае, если вы планируете заниматься монтажом гидроизоляции профессионально. Это позволит вам быстро окупить все затраченные средства.

For the introduction are used:

• polymer gels;
• epoxy mixtures;
• acrylate gels;
• special microcements.

Penetration

Проникающая гидроизоляция бетона имеет широкое распространение благодаря простоте использования и высокому качеству конечного результата. WITHоответствующий раствор наносится на поверхность, после чего происходит её попадание в поры и последующая кристаллизация.

Benefits of application:

1. The possibility of use from the inside of the house under the finishing material.

1. The use of water as a catalyst.

Two positive points immediately follow from this:

• The possibility of applying to a wet surface. This will only improve the result.
• «WITHамозалечивание» – в результате появления новой порции влаги даже после длительного периода времени вновь спровоцирует химический процесс кристаллообразования.

1. Vapor permeability Allows you to maintain a favorable microclimate inside the building.
2. Long service life, which is almost equal to the durability of the concrete itself.
3. Simple application instruction.

Tip: It is recommended to use a spray gun. It will significantly speed up and facilitate the process.

The disadvantages of this option are very minor:

1. The combination is possible only with concrete. On the other hand, we also consider the protection of this particular material from moisture.
2. In the process of applying the necessary temperature of not less than +5 degrees Celsius. That is, either choose the summer period, or process the wall from inside the building.

The best representatives of this type of waterproofing today are the Millennium and Penetron brands of Spanish production.

WITHоздание разделительного слоя

Applying coating waterproofing on a concrete surface allows you to create a reliable water-repellent layer between the wall itself and the finishing material. It has the following features:

It is possible to distinguish the following types of this type of protection from moisture, depending on the base used and their characteristic technical characteristics:

Tekmadray elast - a two-component, hard-elastic material will be an excellent choice for the implementation of coating waterproofing.

Adding to the solution

WITHуществует множество модифицирующих добавок, позволяющих ускорить или замедлить темпы застывания, защитить от замерзания, усилить прочность. Также существуют и такие, которые попадая в бетон, кристаллизуются в нём, предотвращая проникновение воды.

In the method of using this moisture protection lies at the same time its advantage and disadvantage. Plus, ease of use, since you only need to pour the purchased solution into the total solution. The downside is that this can only be done at the concreting stage.

Conclusion

Concrete, despite its excellent strength, may eventually suffer from water. To avoid this, use one of the ways to improve the moisture resistance of cement, a brief summary of which is summarized in the following table:
