Simpson Strong-Tie 9 Oz. Crack-Pac Flex-H2O Polyurethane Concrete Sealant Kit

Description

Simpson Strong-Tie offers reliable, easy-to-dispense products for a variety of restoration applications, including structural restoration, pick-proof sealing and water-intrusion prevention. The Crack-Pac Flex-H2O polyurethane injection resin seals leaking cracks, voids or fractures from 1/32-in. 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.
