COLPHENE® BSW V is an SBS-modified bitumen, self-adhered waterproofing membrane for use in approved blind side waterproofing assemblies. COLPHENE BSW V is composed of a proprietary formulation of elastomeric styrene-butadiene-styrene (SBS) polymer modified bitumen and is reinforced with a tough, dimensionally stable composite polyester/glass fiber reinforcement. COLPHENE BSW V is designed specifically for vertical pre applied/blind side waterproofing applications. The topside is surfaced with fine mineral aggregate and the underside is covered with a silicone release film that is removed during application.

Product Properties

  • Installation Method Self Adhered
  • Material Catalyst


Prior to installation, unroll COLPHENE BSW V and allow to relax. Loose lay COLPHENE BSW V in desired position on approved prepared substrate. Once the membrane is in the desired location, remove the release film on the back side of the membrane and the DUO SELVEDGE side lap. Apply even pressure using a membrane roller over the entire surface, including the side lap to ensure adhesion. Once the self-adhered portion of the lap is adhered, a heat welding device is used to seal the lap. Refer to the SOPREMA® SBS Waterproofing Manual for additional application guidelines.
