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 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.

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.

They include:

  • Deck systems

  • Detail tape

  • Cementious and epoxy grouts

  • Hydrophilic sealants

  • Tieback covers
