The composition of the waterproofing

As a rule, it is used to prevent corrosion of building structures.

  • durability.

waterproofing can be applied in the following types of surfaces:

  • concrete;
  • wood;
  • roofing;.
  • metal etc.


Specifications material:

  • By pulling, the force at which the gap can be from 37 to 60 kg;
  • hundred percent hydrophobicity;
  • elasticity;
  • temperature brittleness of the top layer of the material is 15 degrees;
  • He is able to withstand the temperature of 85 degrees for two hours;
  • minimum service life of 15 years.

Features liquid waterproofing bit different:

  • Withstands temperatures up to 100 degrees;
  • Water absorption is 0.2%;
  • Dry ostatok- 65%;
  • completely dry from 15 hours to two days;

  • may serve more than 30 years.
