High performance gas resistant, waterproof membrane for basements and structures.
A cold applied flexible methane, radon and carbon dioxide resisting waterproof membrane incorporating an aluminium layer and a polymer modified bitumen compound on a high strength polymer backing film.
It provides a vapour and waterproof membrane to water excluding structures and protects concrete form attack by aggressive ground salts. The aluminium layer also provides methane, radon and carbon dioxide resistance, protection against damage and gives dimensional stability.
