TREMproof® 250GC Single-Component, Rapid Curing, Fluid-Applied Elastomeric Waterproofing Membrane

Tremco TREMproof® 250GC | Single-Component Fluid-Applied Waterproofing Membrane

Single-Component, Rapid-Curing, Fluid-Applied Elastomeric Waterproofing Membrane | Brand: Tremco

Tremco TREMproof® 250GC is a single-component, moisture-curing, fluid-applied polyurethane waterproofing membrane designed for below-grade and plaza deck applications. Its rapid-cure, green concrete compatible (GC) formulation is designed for professional waterproofing contractors. Confirm suitability, coverage, cure time, and system compatibility against the current Tremco TDS, SDS, and project specification before use.

Key Characteristics

• Single-component, moisture-curing — no mixing required; apply directly from the container.
• Rapid-curing — designed for faster cure than conventional membranes; confirm cure times against the current TDS as they vary with temperature and humidity.
• Green concrete compatible (GC) — designed for application to green concrete; confirm minimum concrete age and moisture requirements against the current TDS.
• Seamless, fully-adhered membrane — fluid-applied to form a continuous waterproofing layer; final performance depends on substrate condition, preparation, and application method.
• Crack-bridging elastomeric properties — designed to accommodate minor substrate movement; confirm crack-bridging performance against the TDS and project specification.
• System compatible — designed for use with Tremco protection boards and drainage composites; confirm system compatibility against the current Tremco specification before ordering.

Typical Applications

• Below-grade foundation wall waterproofing
• Plaza deck and podium deck waterproofing
• Split-slab and buried deck waterproofing
• Green concrete substrate waterproofing

Surface Preparation

Concrete must be structurally sound, clean, and free of laitance, oil, grease, curing compounds, and form release agents. Confirm minimum concrete age, surface profile, and moisture requirements against the current Tremco TDS. Apply approved primer where required by the system specification. Refer to the current Tremco system specification for full substrate preparation requirements.

Limitations

• Must be used as part of an approved Tremco waterproofing system — not a standalone exposed membrane.
• Do not apply to substrates with active water leaks or running water.
• Do not apply below minimum temperature or when rain or condensation is expected before cure; confirm temperature requirements against the TDS.
• Cure time is temperature and humidity dependent — confirm against the current TDS.
