The Crack-Pac® Flex-H2O Polyurethane Injection resin seals leaking cracks, voids or fractures from 1/32 to 1/4 in wide in concrete or solid masonry. Designed to perform in applications where water is seePing or mildly leaking from the crack, the Polyurethane is packaged in the cartridge and an accelerator is packaged in the nozzle. When the resin encounters water as it is injected into the crack, it becomes an expanding foam that provides a flexible seal in leaking and non-leaking cracks.
