Among the thousands of existing waterproofing materials, choosing the right one can sometimes turn into a long process. Since for each individual case there are certain technical characteristics that the waterproofing material must meet for an excellent and long service life.
In this article we would like to tell you what types of waterproofing materials exist behind the method of application and give some concrete examples of high-quality compositions.
Types of waterproofing materials for the method of applicationIn this article we would like to talk about 5 existing types of waterproofing for the method of application: coating, penetrating, roll, injection and membrane.
Obmazochnaya
Coating waterproofing has several subspecies:
- elastic;
- semi - elastic;
- inelastic.
An example of a high-quality elastic coating waterproofing material is Teknomer 200EX, which consists of two components:
- powder based on cement;
- liquid based on an emulsion polymer.
The material is applied in 2 layers (with a flow rate of 2.5-3 kg / m2) and withstands a positive water pressure of more than 7 atm.
The main advantage of waterproofing of this type over others is considered to be the solidity of the coating, that is, in the finished form there are no seams and joints on the surface, which may eventually be stratified.
Penetrating
The main task of such waterproofing materials is the penetration of the composition into the pores and micropores of concrete to the maximum depth for their clogging and protection from moisture.
This is due to the crystals that are part of the material.
An excellent example is the penetrating waterproofing Teknomer 100, which protects the concrete surface from the influence of positive and negative water pressure.
Sometimes, to get the best effect, masters use both types of waterproofing. The penetrating one is applied first, and after its complete drying, the coating one is applied.
Injection
This type of waterproofing materials was specially created to combat the cracks formed.
The composition is applied through narrow holes in the cracks of concrete under pressure. After a certain time, the material expands and fills all the nearby cracks and microcracks.
Roll
This type of waterproofing is used only on the floor and provides a so-called waterproof barrier against the effects of negative water pressure, for example, groundwater.
This type of waterproofing is applied at the stage of pouring the concrete basin of the pool.
Membrane
This is one of the most difficult types of waterproofing, in which the application occurs as follows:
- liquid membrane waterproofing is applied in several layers to the surface and polymerizes when drying;
- a special reinforcing fabric is laid between the layers, which further increases the strength of the coating.
