Sealing against water

Sealing against water

The polyurethane foam is suitable for sealing against moisture or water. Its applications range from construction through foundations pools up roof waterproofing.

Polyurethane (PUR) foam is an extraordinarily efficient heat insulation, which can also be used as a seal. It is by its closed cell structure throughout the cross-section water-resistant and rot-proof, so it can also be used simultaneously as a waterproofing layer and insulation. The foam can be applied directly to gravel pebbles or foil and on the hardened concrete surface equal. The result is a fully enclosed tub with two functions, insulation and waterproofing.

Pitched roofs usually have the requirement to install a moisture barrier. This usually is a special film, which the moisture out and is vapor permeable from below.
