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 flexible, tough, 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 formulated without harmful phthalates and environmentally friendly or VOC's. The system is comprised of a "B" component (accelerator). The "B" component is used by the applicator to adjust the set times for various job site specific conditions.
