Hyperplas Fibreglass is a high softening point, APPmodified polymeric waterproofing membrane manufactured to highest international standards. It consists of a center core of non woven Fibre glass mat for extra mechanical strength. The center core is protected on both sides with Polymeric Asphaltic mix, which has high penetration, high heat resistance and high softening point. With high tensile strength, the membrane is still extremely flexible and pliable to adapt to contours. For this reason this membrane makes an ideal waterproofer. Hyperplas Fibreglass is also available with dual centre core of a High Molecular High Density Polyethylene film. This additional polyethylene core provides additional security. Hyperplas Fibreglass is available in grades of 1.5mm, 2mm, 3mm, 4mm, 3Kg, 3.5Kg or 4Kg/sqm

SuperThermoLay® is an uniquely formulated pre-fabricated plastomeric waterproofing membrane with spun bonded polyester mat at its core. SuperThermoLay® 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. SuperThermoLay® 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. SuperThermoLay® 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.
