Gripset BRW HD- Reinforced Butyl Rubber Waterproofing


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 unrivaled 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. As a non-bituminous system, termination points at ground level or above earth lines have no risk of bleeding or yellowing into wall surface finishes. The BRW-HD system along with the BRW-PF grade enables the direct adhesion of finishes over the membrane including tiles, renders, textures, paints systems, and decorative finishes.
