InjectProECO-CombiGrout is a slightly flexible, tough, closed cell, polyurethane injection grout designed for grouting into voids and cracks. When it comes in contact with water, the grout expands 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.
