Gripset BRW HD

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 excellent 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. Forming an instant waterproof seal when applied onto surfaces, the BRW HD system avoids downtime for drying or curing, delivering rapid application times to enable areas to be in service immediately upon waterproofing completion.

• Outstanding high bond adhesion to applied surfaces

• Excellent performance in low to high temperatures, -30ºC to 80ºC
