TREMproof® 250GC

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.

60 mils.

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.
