Lining membranes stop the penetration of hazardous substances into the environment surrounding the construction. They hold substances or water stored in the premises designed for this purpose, protect the constructions and indoor environments from undesirable effects of water, and prevent or reduce penetration of gases (radon, methane) into buildings.
Key properties of lining membranes:
Permeability to liquids - EN 14150
Gas permeability - ASTM D 1434
Watertightness - EN 1928
Radon diffusion coefficient - ISO/TS 11665-13
