Viper II 15-mil is a unique high strength polyolefin-based under-slab vapor barrier specifically designed for preventing moisture migration through concrete slabs on-grade. Viper II 15-mil reduces water vapor emission transfer and moisture migration from entering the building envelope on commercial, industrial and residential applications. Viper II 15-mil controls condensation, mold, mildew, degradation and prevents costly flooring failures and damage to moisture sensitive furnishings within a
building’s interior. Viper II 15-mil may be used to reduce radon and methane gas migration and is resistant to other adverse soil conditions.
