Hydrophobic, potable water approved, polyurethane grout


InjectPro-61 is a low viscosity hydrophobic polyurethane injection grout designed to fill joints and cracks in concrete, and stop active water leaks. The system is comprised of an “A” component (base resin) and a “B” component (accelerator). The “B” component is used by the applicator to adjust the set times for various job site specific conditions. InjectPro-61 is NSF/ANSI Standard 61 certified for use in contact with potable water.

The closed cell foam created by reaction with small amounts of water will maintain its physical form and not be subject to shrinkage due to wet/dry cycles.

Typical Applications:

Any concrete structure with water leaks such as:
Potable Water Retaining Structures
Waste Water Treatment Plants & Manholes
Concrete Dams
Storm Water Systems
