The Product in Brief
Proofex Torchseal is a high quality modified torch applied membrane manufactured from premium grade heavily modified SBS (styrene butadiene styrene) or APP (atactic polyproylene) bitumen, reinforced with a core of non-woven polyester fabric. The core has a weight of 180/gms/m 2, it does not rot and is malleable. The core gives the membrane its excellent mechanical properties, allows for good elongation, and affords high resistance to piercing. The chemical resistance of Proofex Torchseal makes it particularly suitable for tanking applications in areas where aggressive ground water conditions prevail. When used as a DPM Proofex Torchseal should be protected by Proofex Guardsheet for walls, and by using a sand/cement screed or fibre cement boards for floors.
