PetroGrip SBS Waterproofing Membrane TDS
Polyester-reinforced SBS-modified torch-applied bitumen membrane — 3 mm nominal thickness, 60/70 bitumen base.
PetroGrip SBS is a prefabricated SBS-modified bituminous sheet membrane for roofing and structural waterproofing. The compound uses 60/70 penetration-grade bitumen modified with SBS elastomer; a non-woven polyester carrier provides tensile strength and tear resistance.
The underside is finished with a heat-activated polyethylene film for torch application. Upper surfaces may be specified with polyethylene film, sand, or mineral granules according to system position.
