BookmarkThe 20FT concrete crack repair kit is a hydrophobic polyurethane meant to repair wet or leaking cracks in concrete walls and floors. This kit can also repair dry cracks in concrete walls by simply adding water with a spray gun or turkey baster.
How It Works:
Foundation Armor’s hydrophobic polyurethane repair kits are designed to stop water and permanently repair wet cracks in concrete walls, floors, and building structures. Using a 5,000 PSI injection gun, the polyurethane solution is injected into the crack through aluminum injection ports. When the solution comes into contact with water it transforms into a foam and expands 40X, repairing the crack from the back of the crack to the front of the crack.

HydroStop Crack Repair Instructions
Where To Use:
- Cracks in concrete, brick, cement, and gunite.
- Cracks on horizontal and vertical surfaces.
- Cracks that are dry, wet, leaking, or gushing with water.
- Pipe penetrations, cold joints, small holes, and coveseams.
Preparation:
Clean out the crack. Make sure the crack is free of loose materials. If the crack has been previously repaired, remove repair materials completely.
Application:
- For hairline cracks, insert injection ports into the concrete every 6-12 inches. For larger cracks, insert injection ports into the concrete every 12 inches. Ports should be injected at a 45 degree angle into the center of the crack. In some cases, the injection ports can be injected directly in through the face of the crack.
- Using water, test that the injection ports were properly inserted and that the crack is accepting water through the ports.
- Mix the polyurethane solution and accelerator into the injection gun and screw the lid on.
- Attach the injection gun to the ports and pump the material into the crack through the ports. Start at the first, or bottom, port first.
- Move up/down the crack until the crack has been repaired.
- Wipe away any extra materials and let dry.
Dry Time:
Let dry 24 hours. Reaction is immediate, water will stop on contact.
