Which product can be used to waterproof the basement from the inside?

Waterproofing from the inside should be made with a product that has excellent  adhesion to the substrate and that is also vapour-permeable (breathable).

These requirements are met by IZOCHEM APF 1K, a one-component sealing micro-mortar. The total thickness of the waterproofing should be 3 mm. The first layer should be rubbed firmly into the substrate with a hard bristle brush with. After drying, a coating resistant to negative water pressure is formed. We deal with such an impact when the water passes through the partition, “tearing off” the waterproofing from the proofed surface.
