Simpson Strong-Tie CPFH09 Crack-Pac Flex-H2O Polyurethane Crack Sealer

The Crack-Pac Flex-H2O polyurethane injection resin seals leaking cracks, voids or fractures from 1/32″ to 1/4″ 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. Easily dispensed with a standard caulking tool, the Crack-Pac Flex-H2O can also be used on dry cracks if you wet the surface area first. The quick reacting chemicals begin expanding within one minute of installation with a 20:1 expansion ratio.
