Torch applied 4mm thick, reinforced elastoplastomeric polymer, bitumen waterproofing membrane


Proofex Torchseal A800 is manufactured by co-extrusion of an elastoplastomeric bitumen-polymer compound and of a non-woven polyester reinforcement with a continuous filament placed in the thickness of the membrane.
The lower face of the membrane is manufactured with a sacrificial polyethylene film which prevents sticking when
the membrane is in storage.
Proofex Torchseal A800 has the top face treated with talc, which also works to make the product easier to unroll and apply.


Proofex Torchseal A800 is used as a continuous waterproofing membrane for foundations, basements and tunnels.


  • APP polymer modified -specifically selected for Australian conditions
  • Handles ponding and permanently wet conditions
  • No curing times. Instantly waterproof
  • Uniform thickness – eliminating likelihood of uneven application possible with liquid applied membranes
  • Excellent stability at both high and low temperatures
  • Excellent durability and flexibility
