Hydrophobic, flexible polyurethane grout for stopping active leaks in cracks


InjectProECO-LV is a closed cell, high performance polyurethane injection grout designed for use to cut off gushing water leaks with a high flow rate and/or high hydrostatic pressure in low range dynamic cracks. When it comes in contact with water, the grout expands up to 800% and quickly cures to a tough, flexible, closed-cell polyurethane foam that is generally unaffected by common corrosive environments and is not subject to shrinkage due to wet/dry cycles. InjectProECO grouts are all environmentally friendly and formulated without harmful phthalates or VOC’s.

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.

Typical Applications:

  • Any concrete structure with water leaks such as: Water Retaining Structures, Concrete Dams, Tunnels, Elevator Pits,

  • Parking Garages, etc.


  • Zero VOC’s - meets LEED criteria
  • 100% solids, non-flammable, non-toxic permanent seal
  • Hydrophobic - can be used in wet and dry environments
  • Accelerator and resin stable to -40°F.
  • Pumped as a single component
  • Excellent elongation creates a tight seal in moving cracks
  • Adjustable reaction times
  • Non-hazardous shipping
