The Preprufe System is a flexible, multi-layered composite sheet membranes comprising a white HDPE film, highly aggressive pressure sensitive adhesive and a weather resistant protective coating layer.
The Preprufe membranes provide a passive protection system that does not rely upon hydration processes or swell in contact with water.
An intimate bond is formed to the poured in-situ structural concrete by means of a pressure sensitive adhesive preventing lateral water and moisture migration between the membrane and structure.
Preprufe membranes are chemically resistant in all types of soil or water and protect the structure from salt and sulphate attack. They are tested to withstand a 70m head of water, have a zero permeance to moisture, do not activate prematurely due to wet conditions and are unaffected by ground settlement beneath slabs.
