Our below-ground waterproofing solutions protect commercial buildings and infrastructure in the world's harshest climates. 

Leading the way since 1990 are our reliable Preprufe® waterproofing products. Preprufe® waterproofing membranes create a seal with cast concrete to prevent water migration between the membrane and your structure in every direction. The first membranes designed specifically for blindside applications, Preprufe® membranes shield structures from the damaging effects of water, vapour and moisture.

Preprufe® membranes are easy to install, helping your project stay right on track. Position the roll. Kick it out. Secure the overlaps with Preprufe® ZipLap™ quick-sealing adhesive. That's it — you're done. And when it comes to complete building envelope protection, Preprufe® membranes are in perfect company. Compatible Preprufe® products cover every vulnerability, joint and detail.
