This contractor dual-component FLEXKIT-1050 includes all you need to repair dry, wet, or actively leaking cracks, joints, and various voids in below-grade foundations and concrete structures. It sets fast to form a complete seal throughout the entire thickness of a concrete foundation wall which expands 400% to 600% and cures as a flexible, yet robust, closed-cell foam. The seal will withstand concrete cracking and shifting as the result of thermal cycles, due to its excellent bonding capabilities.

FLEX-1050 is a dual-component, mid-range viscosity, and high-quality crack repair resin designed explicitly for cracks between 1/16" to 5/16" wide.

More Information

This kit includes everything you would need to repair a poured concrete foundation crack of approximately:

  • 1/16" width crack
  • 10' length and 8" thick foundation wall

Really works. Get two people

This stuff worked really well but makes a big mess. First, I recommend you get a helper to put the caps on as you fill the crack. Don't go light on the compound that you cover the crack with. You don't want leaks. Then make absolutely sure that water flows between the ports. If it doesn't, fix it before starting the injection. Get ready for a mess even with a helper. That said, the foam scrapes right off of concrete or plastic tile if you do it just after it's set. I sealed two 10' cracks with this and it worked great!

Excellent product! Got the job done right with no disruption to the exterior of my foundation. No digging and did the work myself. Thank you for making professional materials available to all.

Works fast

Kit complete, product expands fast. Hard to do in crawl space. Maybe should have some kind of check valve because liquid flows fast and no room for error if you need to stop, liquid keeps pouring out even with gun released and makes a mess...unless I missed something. Thats why 4 stars
