Polyethylene waterproofing membrane.
Can be applied horizontally as well as vertically and is used in all applications where structures require protection against ground water, seepage, ground gas, hydrocarbons, volatile organic compounds (VOCs) and other contaminants.
Typically used in the following constructions:
A multi-layer polyethylene membrane with an adhesive coating for post applied vertical applications as a waterproof membrane, specifically designed and manufactured to perform as a methane, carbon dioxide, radon, volatile organic compounds (VOCs), hydrocarbon and ground gas protection system.
It complies with the latest codes of practice as published by BRE, CIRIA (748) and BSI (BS 8485 and BS 8102). It is suitable for use as ground gas/ hydrocarbon protection for NHBC Green, Amber1, Amber2 and Red sites.
It comprises of Memtech Titan and a specialist all weather adhesive backing to provide a bonding layer for specifically waterproofing applications, providing Type A barrier protection in accordance with BS 8102. Immersion testing has also been completed for chemical resistance to BS EN 14414 and BS EN 14415. CE marked to BS EN 13967.
