Simpson CPFH09 Crack-Pac Flex-H2O 9 oz. Polyurethane Crack Sealer Cartridge from Simpson Strong-Tie is a polyurethane injection resin engineered to seal leaking cracks, voids, and fractures from 1/32 in. to 1/4 in. wide in concrete or solid masonry. Designed specifically for applications where water is seeping or mildly leaking from a crack, this cartridge-based system reacts with moisture to become an expanding foam that delivers a flexible, lasting seal in both leaking and non-leaking cracks.

Key Features

• Seals seeping or mildly leaking cracks
• Can be dispensed with a standard caulking tool
• Can also be used on dry cracks if water is introduced to 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
• 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

Frequently Asked Questions

How does the Crack-Pac Flex-H2O work when injected into a wet crack?

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. The polyurethane is packaged in the cartridge and an accelerator is packaged in the nozzle, so the two components combine upon dispensing.

Can this product be used on dry cracks?

Yes. The Crack-Pac Flex-H2O can also be used on dry cracks if water is introduced to the affected area, allowing the moisture-activated expansion reaction to occur.

How fast does the Crack-Pac Flex-H2O react after application?

The reaction begins within 1 minute after exposure to moisture, and expansion may be completed within 3 minutes, depending on the amount of moisture and the ambient temperature.

What tool is needed to dispense this cartridge?

The Crack-Pac Flex-H2O cartridge can be dispensed with a standard caulking tool, making it straightforward to apply without specialized dispensing equipment. The compatible tool is the Simpson Strong-Tie CDT10S.
