Waterproofing
Polyurethane SystemsFoundations & Retaining Walls Waterproofing
Essential external waterproofing for every building with a basement.
Overview
A polyurethane liquid-applied waterproofing membrane for foundations and retaining walls constantly exposed to ground humidity. Foundation waterproofing prevents serious structural and decorative damage from sustained moisture ingress. The highly elastic membrane forms a seamless, fully bonded barrier, accepts loose-lay protection sheets and bonded insulation boards, and remains flexible from −50 °C to +90 °C — the widest service temperature range in the Numastec polyurethane range.
