TREMproof® PrePly™

Chemically Adhered, Sheet-Applied, Blindside Waterproofing Membrane

TREMproof® PrePly™ is a pre-applied waterproofing membrane created specifically for blindside, zero-lot line, and below slab on grade waterproofing applications. TREMproof PrePly is composed of an HDPE sheet combined with a weather resistant adhesive, creating a robust, watertight, membrane ideal for even the most critical projects. Designed with the applicator in mind, PrePly’s laps include an integrated adhesive edge, allowing for a simple seaming solution.
