COLPHENE® BSW Protect’r is an SBS-modified bitumen waterproofing membrane for use as a protection sheet in approved blind side waterproofing assemblies. COLPHENE BSW Protect’r is composed of a proprietary formulation of elastomeric styrene-butadiene-styrene (SBS) polymer modified bitumen and is reinforced with tough, dimensionally stable composite polyester/glass fiber reinforcement. The topside is surfaced with fine mineral aggregate and the underside is surfaced with a protective polyolefin release film that is removed during application.
Prior to installation, unroll COLPHENE BSW Protect’r and allow to relax. Place COLPHENE BSW Protect’r over installed COLPHENE BSW H in desired position. Then remove the release film and roll with a weighted roller. Refer to the SOPREMA® SBS Waterproofing Manual for additional application guidelines.
