SWELLPRUFE® Waterproofing Membrane
We made bentonite better.
SWELLPRUFE® is a next-generation, pre-applied waterproofing membrane that rethinks traditional bentonite mats.
Dynamic, self-sealing bentonite swells to fill gaps and defects when exposed to moisture. A fully bonded rubberized asphalt layer delivers a superior bond to concrete and reliable protection against lateral water migration.
With unique non-slip kickout rolls, SWELLPRUFE is a safer, faster-installing solution backed by GCP’s 25+ years of below-grade waterproofing expertise.
High Performance Combining the proven bond-to-concrete technology owners and applicators expect from GCP with the proven benefits of traditional bentonite without its typical pitfalls. This synergy ensures long-term durability, superior crack resistance, and consistent protection even under hydrostatic pressure.
Walkable & Workable The trafficable surface of SWELLPRUFE™ ensures jobsite safety by providing a stable, non-slip membrane that crews can walk on-even when wet. This minimizes work stoppages and delays, keeping construction timelines on track regardless of weather conditions. Lightweight rolls with large coverage area speeds installation and lowers cost.
Right Product in the Right Scenario Specifically designed for commercial buildings, basements, and other foundational structures where reliability and simplicity matter most. Usable in both horizontal and vertical applications, SWELLPRUFE® is another innovation from GCP, the leader in below-grade waterproofing systems.
