Preprufe® 160 Flex

A waterproof membrane comprising of a composite sheet with a robust flexible backing, a pressure sensitive adhesive and a trafficable weather resistant coating. It develops a continuous adhesive bond to concrete poured against it, which prevents water migration between the structure and the membrane, substantially reducing the risk of leaks.

Application:

• Water and vapour proofing all basement grades to BS 8102:1990.

• Waterproofing civil engineering substructures.

• Methane, carbon dioxide and radon gas protection in excess of the standard membrane requirements in BRE report 211 and 212.

Advantages:

• Can be used with irregular profiles such as sheet, secant or soldier piling.

• Lightweight and flexible, easy to handle and install without special corner pieces.

• Excellent chemical resistance.

• Inert, unaffected by groundwater conditions.

System components:

• Preprufe® 160 Flex – used typically in the vertical position against irregular permanent shuttering.

• Preprufe® 300R – used typically with concrete slabs thicker than 350 mm.

• Preprufe® Tape LT – incorporating Preprufe® coating for continuous concrete adhesion at laps and detail.

• Bituthene® LM – high performance membrane for detailing terminations such as pipe penetrations.

• Adcor® 500MI/ 500S – hydro-expansive waterstop for concrete construction joints.
