Description

TREMproof® 250GC is a high-performance, single-component modified polyurethane waterproofing membrane designed to protect below-grade concrete and masonry structures from water intrusion. This 10-pack of 5-gallon pails is ideal for contractors and large commercial waterproofing projects, providing coverage for foundations, retaining walls, planters, split-slab applications, and other demanding waterproofing jobs. Its rapid-curing, high-solids formula can be applied to damp or green concrete as soon as 24 hours after form removal, helping reduce project delays. TREMproof 250GC can be applied in a single lift up to 120 mils or built up in multiple lifts for enhanced protection. The membrane is compatible with Tremco sealants, coatings, and expansion joints for reliable detailing around penetrations and transitions.

Application Details

Surface Preparation

  • Ensure surfaces are clean, sound, and free of contaminants before application.
  • Concrete forms must be removed at least 24 hours before application.
  • May be applied directly to damp or green concrete.

Application

  • Apply up to 120 wet mils in a single lift.
  • For additional protection, build the membrane up to 215 wet mils using multiple applications.
  • Use the appropriate Self-Leveling, Roller, or Trowel grade based on project requirements.

Limitations

  • Backfilled installations require a compatible Tremco protection course.
  • Do not use as an exposed or traffic-bearing surface.
  • Do not apply over curing compounds, forming oils, or contaminated substrates.
  • Not approved for direct contact with asphalt-based products or potable water.

Storage & Safety

  • Store unopened containers between 40°F and 100°F (5°C–37°C).
  • Use adequate ventilation during application.
