Crack-Pac® Flex-H2O™ is a high solids hydrophobic polyurethane injection resin designed to seal leaking cracks, voids or fractures in concrete or solid masonry. The polyurethane is packaged in the cartridge and an accelerator is packaged in the nozzle. When the two are combined in the cartridge and mixed, the result is a low viscosity, water activated polyurethane. 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.

Crack-Pac® Flex-H2O™ crack sealer is also available in the Crack-Pac Flex-H2O Injection Kit. The kit includes everything needed to pressure inject approximately 8 lineal feet of cracks:

  • 2 Crack-Pac Flex-H2O cartridge/nozzle sets
  • 12 E-Z-Click™ Injection Ports
  • 2 E-Z-Click™ Injection Fittings with 12" tubing
  • 1 pint of paste-over epoxy (8 oz. of resin + 8 oz. of hardener)
  • 4 disposable wood paste-over applicators
  • 1 pair latex gloves
