Product Description
The Simpson CPFH09KT Crack-Pac FLEX-H2O Polyurethane Crack Sealer Kit by Simpson Strong-Tie delivers a complete, all-in-one solution for pressure injecting and permanently sealing leaking cracks, voids, and fractures in concrete and solid masonry. Designed specifically for applications where water is actively seeping or mildly leaking, this polyurethane injection resin expands on contact with moisture to create a durable, flexible foam seal - stopping water intrusion and restoring structural integrity with minimal material and effort.
Key Features
- Seals seeping or mildly leaking cracks in concrete and solid masonry from 1/32 in. to 1/4 in. wide
- Seals leaking cracks, voids, or fractures - provides a flexible seal in both leaking and non-leaking cracks
- Can be dispensed with a standard caulking tool for easy, controlled application
- Can also be used on dry cracks if water is introduced to the affected area
- Can be used with a reduced amount or without accelerator to slow down reaction time
- Expands to fill voids and seal the affected area completely
- Fast reacting - reaction begins within 1 minute after exposure to moisture; expansion may be completed within 3 minutes (depending on the amount of moisture and the ambient temperature)
- 20:1 expansion ratio (unrestricted rise) means less material needed per application
- Polyurethane resin packaged in the cartridge; accelerator packaged in the nozzle for convenient, two-component mixing during injection
- Made in the United States

Frequently Asked Questions
- What types of cracks can the Crack-Pac FLEX-H2O seal?
- The Crack-Pac FLEX-H2O polyurethane injection resin is designed to seal leaking cracks, voids, or fractures from 1/32 in. to 1/4 in. wide in concrete or solid masonry. It is specifically formulated to perform in applications where water is seeping or mildly leaking from the crack, and it also provides a flexible seal in non-leaking cracks.
- Can this product be used on dry cracks where there is no active water seepage?
- Yes. The Crack-Pac FLEX-H2O can also be used on dry cracks if water is introduced to the affected area. The polyurethane resin requires moisture to activate its expansion - so wetting the crack surface prior to injection will initiate the foaming and sealing reaction even in the absence of active water intrusion.
- How quickly does the Crack-Pac FLEX-H2O react after injection?
- The product is fast reacting - the reaction begins within 1 minute after exposure to moisture, and expansion may be completed within 3 minutes, depending on the amount of moisture present and the ambient temperature. The 20:1 expansion ratio (unrestricted rise) ensures thorough void fill with less material.
- What special equipment is needed to apply the Crack-Pac FLEX-H2O?
- No specialized equipment is required. The Crack-Pac FLEX-H2O can be dispensed with a standard caulking tool, making it accessible for a wide range of users. The CPFH09KT kit also includes E-Z-Click injection ports and fittings with tubing, paste-over epoxy, applicators, and gloves - everything needed to pressure inject cracks without sourcing additional supplies.
