COLPHENE BSW H 4.5

COLPHENE BSW H 4.5

COLPHENE® BSW H 4.5 is a high performance, fully bonded composite sheet membrane designed for blind side waterproofing assemblies in pre-applied horizontal below grade waterproofing applications. It is composed of a proprietary blend of Elastomeric Styrene-Butadiene-Styrene (SBS) modified bitumen combined with Ultra-High Strength (UHS), dimensionally stable reinforcement system (heavy duty non-woven polyester). The top surface is treated with a Specially Engineered Silicon Dioxide Crystals while the underside is laminated with a distinct synthetic film. The unique design of COLPHENE® BSW H 4.5 and the unique DUO SELVEDGE technology allows for homogenous bond to structural concrete, resistance to hydrostatic pressure, lateral water migration and precise alignment of side-laps to be heat-welded using propane torch or a hot air gun.
