With the AMAZING wall crack repair sealant... CRACK

Crack foundation wall repair

Foundation walls develop cracks from settling, which often leak water. Stop the leaks with a single application of the amazing do-it-yourself CRACK foundation wall repair sealant. CRACK is a resilient surface seal. No chemical mixing, no pressurized injections, just one easy do-it-yourself step. CRACK is a new generation sealant that will save you hundreds of dollars over contractor's remedies.

Tools Needed:

  • CRACK Foundation Repair (1 tube of CRACK seals approximately 10 feet.)
  • Putty knife
  • Cylinder drill attachment to clean surface (also know as a wire power stripper)
  • Air hose or can of pressurized air

Step 1
Simply clean the surface with a drill attachment that is best described as a cylinder with infrequent coarse steal wires loosely nicking away at the concrete surface.

Step 2
Then blow the surface clean with an air hose.

Step 3
With the surface dry, squeeze a thick bead of CRACK along the wall crack quickly followed with a 1-1/2” wide plastic putty knife, creating a 1/4” thick ribbon of CRACK down the wall. If the leaking wall crack leads all the way down to the floor line, leave the bottom 3" of the wall crack open and install the SquidGee Dry System.

Step 4
The next day most of the CRACK will absorb into the porous cement wall leaving a VERY tough 1/8” thick, smooth ribbon on the wall.
