Application of liquid glass for waterproofing in construction

The foundation is the foundation of the house, the guarantee of its long-term service to the person. Unfortunately, he faces a number of dangers, the main of which is moisture. However, there are many ways that you can protect the foundation from harmful erosion.

One of the most effective is the use of liquid glass for waterproofing. You probably know its composition, since with clerical glue (silicate) , almost every schoolboy was involved.

First of all, make sure you use the solution of silicates (glass). It is very important to check it for the amount of foreign impurities. Quality liquid glass (use for waterproofing is more than justified) should have a thick and even consistency. If the packaging was sealed, then even multiple defrosting and freezing will not have any effect on its properties.

Glass can be used in three different ways:

• Coating. As you can guess by name, the use of liquid glass for waterproofing In this case it is limited by its simple application to the protected surfaces. It should be noted that it is necessary to smear concrete in two steps, since the first layer is almost completely absorbed, filling the outer pores of the material.
• The use of cement mortar mixed with liquid glass. Note that this composition stiffens with stunning speed, so that most often it is made for the rapid elimination of large cracks and leaks. In addition, it is ideal for filling gaps in a prefabricated structure.
• The most reliable is the waterproofing of the foundation with liquid glass, When it is used only as an additive to mortar. In this case, the cement hardens at a moderate speed, and the technical characteristics of the finished structure are increased several times. But there is only one nuance: the exact amount of additive you will have to rely on yourself, since there are no universal schemes.

Having dealt with the basic concepts, let's talk about how in the construction of the application of liquid glass for waterproofing in the form of a coating.

First of all, it is necessary to properly prepare the surface of concrete for applying a solution of silicates to it. Work should be carried out as carefully as possible, as this affects the quality of the adhesion of liquid glass to concrete. It is necessary to clean the surface of the foundation from dust and dirt, then use a brush or roller to apply the first layer of the composition.

After half an hour, a second coat is applied. At the same time, care must be taken to ensure that there are no poorly treated areas on the concrete, which were only walked once. After this, we prepare the main waterproofing layer: we knead the cement on a solution of silicates, applying it as soon as possible to the foundation. Take into account that at one time you need to prepare the amount of solution that you will have time to apply during the time of its solidification. After performing the coating, you can immediately begin to insulate the base part. Wait for further solidification is not worth it.

As you can see, the use of liquid glass for waterproofing is not a particularly difficult technique.
