Concrete crack repair that routs, cleans and fills hairline and larger cracks with flexible or rigid repair materials before a garage floor coating goes down.
Almost every garage slab has cracks. Some are hairlines from shrinkage, some are wider from settling and some follow the saw cuts. If they are not repaired, they can telegraph through a coating and, in the worst case, let it fail. A good repair makes the floor look uniform and keeps the coating from cracking along the old lines. In Nashville, clay soils and temperature swings move slabs more than owners expect, so we pay special attention to cracks that are active.
We first sort cracks by type: stable hairlines, cracks that move with the seasons and cracks with a height difference across them. Then we open the crack with a grinder or a small blade, clean it and fill it with a material chosen for the job, such as a rigid epoxy for stable cracks or a flexible filler where movement is expected. The surface is smoothed flush and ground. We are honest that a coating cannot stop a slab from moving, and we explain when a crack may reappear and what we can do about it.
Stable, moving and offset cracks get different repairs.
Fillers bond better in clean, open cracks.
Rigid or flexible, chosen for how the crack behaves.
We explain when a crack may move again.
Stable, moving and offset cracks get different repairs.
Cracks are routed and cleaned so fillers bond.
Rigid or flexible fillers fit the crack's behavior.
Repairs are ground smooth before coating.
We explain when a crack may move again.
Repairs are planned with the coating in mind.

Stable cracks that are properly filled usually stay hidden. Active cracks can reappear, and we tell you which is which.
Yes, with routed and filled repairs, though large movement may call for a structural opinion.
Most cracks are repaired during the prep visit, with a short cure before coating.
A good repair is ground flush and hidden under flakes or a solid color.
No. It protects the surface, but it does not stop the slab from moving.
