TREMproof® 4000M is a heavy duty, 180g/m2 high strength, non-woven polyester mat impregnated and coated with a tough APP modified bitumen compound. It is surfaced with a coating of mineral slate chips which provide UV protection and makes the membrane suitable for light pedestrian maintenance traffic.
The TREMproof 4000M torch applied membrane system is perfectly suited to waterproofing concrete roofs and decks where an exposed and light pedestrian maintenance trafficable waterproofing system is required.
