## Description

Avoid expensive repairs to cracks in your foundation by fixing them yourself using Flexomeric crack repair kits for foundations and basements. Flexomeric includes only the highest-quality concrete crack repair materials in its repair kits in order to insure that you successfully fill in cracks completely from the inside of the foundation wall through to the outside. The Flexomeric FLEXKIT-100 contains 2 single component, mid-range viscosity, high quality crack repair resin, crack surface paste and port adhesive, and ports needed to repair up to 8' long, 1/16" thick concrete foundation crack in an 8" thick wall. Flexomeric Crack Repair Resins can be injected into an actively leaking crack as it chemically reacts with water and bond to concrete to form a water-tight, flexible gasket through the entire wall thickness, eliminating any future leaks, guaranteed. Application is easy enough for even novices to do it like a pro. Please note that the kit does not include an injection gun and spray bottle, which are required for application.

## Questions & Answers

**Q: Can this be used to repair a crack in concrete foundation poured 50 years ago?**
A: Absolutely!  There is no issues in using the Flexomeric resins to repair older poured concrete foundations.

**Q: Can this be used on a block foundation?**
A: I don’t see why not. I usually drill holes about 7 inch spacing to get the resin in deep. 
Block is hollow but may be filled with cement so you may need extra resin which you can purchase. If the crack is wide then drilling may not be required. Good luck

**Q: My crack is about an inch wide and about one ft in length. Can i still use this product?**
A: The product says that it’s for cracks 1/16” to 1/2” wide. But it’s so easy and cheap compared to alternative fixes that I would still try it.

**Q: How many feet does one kit cover?**
A: I'd say 8-12 feet of crack.  The deciding factor is the number of ports and the amount of epoxy, not the foam itself.  And I was very happy with the kit.
