Gripset BRW-HD is a self-adhesive butyl rubber sheet membrane with a laminated high strength HDPE film facing designed for subterranean waterproofing and multi layered sheet membrane applications.

The high tack butyl backing provides a high performance waterproof layer with unrivalled adhesion to porous and non-porous surfaces in a wide range of temperature conditions. BRW-HD membrane has outstanding resistance to vibration, movement and flexing, delivering a waterproofing system that overcomes the limitations of bitumen self tack and heat applied sheet membranes.
