Concrete Crack Cleaning in Rochester, NH

Yes, crack cleaning is required before sealing. Dirt, dust, and loose concrete inside a crack will prevent the sealer from bonding correctly.

We remove loose material, debris, and residue from inside the crack using mechanical scraping and air or vacuum clearing. This gives the crack a clean, open surface that repair materials can bond to.

Filling a crack without cleaning it first shortens the life of the repair. Residue and loose concrete inside the crack break down adhesion and cause the filler to fail sooner.
