Below-ground, pre-applied waterproofing for the most complex underground construction — effective, durable, easy to install
Leading the way since 1990 are our reliable Preprufe® waterproofing products. Preprufe® waterproofing membranes create seals that prevent water migration between the membrane and your structure in every direction. They were the industry's first pre-applied membranes to permanently shield buildings from water and damaging gas, vapour and moisture.
