The TREMproof® 250GC is a premium single-component, rapid-curing, fluid-applied elastomeric waterproofing membrane engineered to provide long-lasting waterproof protection for commercial and residential construction. This high-solids, VOC-compliant modified polyurethane membrane can be applied to damp and green concrete, allowing construction to continue with fewer weather-related delays. It is available in Self-Leveling (SL), Roller (R), and Trowel viscosities, with the trowel grade intended for detailing work only.

Designed for demanding waterproofing applications, TREMproof® 250GC is ideal for backfilled foundation walls, split slab applications, planters, submerged conditions, and vegetated roofing systems. It is compatible with concrete masonry units (CMU) and plywood substrates, and integrates seamlessly with Tremco sealants, coatings, and expansion joint systems for complete waterproofing assemblies.
TREMproof® 250GC can be applied as little as 24 hours after concrete forms are removed, and may be installed in a single application up to 120 mils thick or built up to a 215-mil high-build system for maximum protection. The self-leveling version can also be catalyzed with water to accelerate curing in cold temperatures and low humidity.
The membrane meets or exceeds ASTM C836, City of Los Angeles (COLA) approval standards, and Miami-Dade County Acceptance, delivering excellent elongation, crack-bridging capability, hydrostatic pressure resistance, and long-term waterproofing performance.
