TREMproof 250GC-R Polyurethane Waterproofing Membrane

Rapid-Curing Polyurethane Waterproofing for Green Concrete

TREMproof 250GC-R is a high-performance, rapid-curing, high-solids modified polyurethane waterproofing membrane. Engineered for efficiency, it is a moisture-cure solution that can be applied directly to "Green" (24-hour old) concrete, significantly reducing project timelines.

Primary Applications

TREMproof 250GC-R provides a seamless, flexible barrier for various surfaces, including concrete, wood, and masonry. It is ideal for:

  • Below-Grade Waterproofing: Foundations and basement walls.
  • Retaining Walls: Critical moisture protection for structural integrity.
  • Tunnels & Planter Boxes: High-performance sealing (use Anti-Root Additive for planters).

Key Features & Benefits

  • AS 4654.1 Compliant: Rigorously tested for external above-ground waterproofing standards.
  • Green Concrete Compatible: Apply to 24-hour old concrete to minimize weather-related construction delays.
  • Single-Component Ease: Eliminates mixing errors associated with plural-component products.
  • High Build Capacity: Can be applied at up to 3mm in a single lift for faster installation.
