STP Superthermo Lay APP Modified Waterproofing Membrane

It is an uniquely formulated prefabricated plastomeric waterproofing membrane with spun bonded polyester mat at its core. It has an excellent resistance to weather and ageing. The core of 160 gsm spun bonded non-woven polyester mat offers an excellent tensile strength, elongation and a superior lap joint strength. The polymer modification of bitumen with Atactic Polypropylene (APP) results in an excellent resistance to hot and cold temperatures It forms an impervious, flexible waterproofing layer which can withstand normal movement of structure without showing any deterioration and serve for a prolonged period of time. It is normally used in protected roofing and waterproofing applications in a single layer system and is also recommended as base layer in multilayer system in various applications, including damp-proofing
