TREMproof® 250GC is a rapid-curing, high-solids, VOC-compliant modified polyurethane waterproofing membrane that can be applied to damp and green concrete. TREMproof 250GC is a one-part moisture-curing elastomer available in three viscosities: Self-Leveling (SL), Roller (R) and Trowel (trowel intended for detailing work only).
TREMproof 250GC is suitable for backfilled walls, between slab and planter applications. TREMproof 250GC may also be used in non-potable water storage tanks.
S/L = Self-Leveling, R = Roller Grade, and T = Trowel Grade.
TREMproof 250GC may be applied at temperatures below 40°F (5°), however, all substrates must be clean, dry and frost-free. It is Tremco’s best recommendation to apply products when substrate and ambient temperatures are at 40°F (5°) and rising. Please note the following when applying these products at temperatures below 40°F (5°).
Special Note: TREMproof 250GC can freeze while in the pail but it will make it very difficult to apply to the substrate and will significantly increase cure times.
TREMproof 250GC requires a protection course. A TREMDrain drainage course may be an acceptable substitute or used as an add-on.
Use of a drainage mat reduces hydrostatic head pressure, affords protection to the membrane and better directs water to the perforated foundation drainage system. Combining a drainage mat with a Tremco below-grade waterproofing membrane typically qualifies for extended warranties.
TREMproof 250GC meets or exceeds all minimum performance requirements of ASTM C 836.
TREMproof 250GC only requires 24 hours following the removal of concrete form work.

Spraying of TREMproof 250GC is not recommended. If a sprayable membrane is preferred or required, TREMproof 260 may be a suitable alternative. Please consult with Technical Service.
After continual exposure to the elements over the years, the sheet-applied waterproofing system below the paver and pedestal system had begun to fail at its numerous seams and moisture had begun infiltrating the occupied spaces.
