Concrete Floor Repair and Coating in Atlanta, GA

Most Atlanta garage and basement slabs have some combination of cracks, spalls, divots, or surface deterioration that needs to be addressed before a coating goes down. Some contractors skip this step — they apply coating over problem concrete and hope the damage is hidden. The result is a floor that looks fine for 60 days and then shows every underlying defect as the coating telegraphs the slab surface beneath it. We repair first, then coat — and we do both in one mobilization so you're not scheduling two separate visits for what should be a single project.

Why Atlanta Concrete Needs Repair Before Coating

Atlanta's concrete slabs show characteristic damage patterns driven by the region's geology and climate. Georgia red clay soils expand and contract seasonally with moisture content — creating movement cycles that crack slab concrete, particularly at control joints, perimeter edges, and mid-slab where differential settlement occurs. Atlanta's freeze-thaw cycles, though milder than northern cities, are sufficient to widen existing surface cracks through winter moisture intrusion and expansion. Summer slab temperatures exceeding 120°F under a closed garage door accelerate concrete surface deterioration and delamination of prior coatings that protect the aggregate.

In Marietta and Smyrna neighborhoods built in the 1960s–1980s, poured garage slabs commonly show aggregate pop-out and surface spalling from decades of tire traffic and occasional de-icer contact. In Alpharetta and Johns Creek new construction, slabs less than a year old may show plastic shrinkage cracks and honeycombing from rapid cure in Georgia summer heat. Each requires different repair materials and techniques before coating can proceed.

Concrete Repair Types We Address

1. 1
   Crack Repair — Cracks are chased (opened with a grinder to create a clean V-groove), cleaned of dust and debris, and filled with semi-flexible polyurea. Semi-flexible filler allows the repaired crack to move slightly with the slab's seasonal expansion and contraction without re-cracking — rigid fillers crack again at the repair site.
2. 2
   Spall Repair — Spalled areas (where the surface concrete has broken away, exposing aggregate) are ground to a stable depth, cleaned, and filled with epoxy mortar or polymer-modified patching compound. The repair is built to flush with the surrounding slab surface before coating.
3. 3
   Divot and Impact Damage Repair — Point-load impact damage from dropped tools or equipment is filled to flush. Small divots can be filled in the grinding pass; larger ones require mortared fill and a cure period before the coating application.
4. 4
   Surface Delamination Repair — Failed prior coatings or delaminating concrete surface layers are ground away completely. A resurfacer or skim coat is applied if the aggregate is fully exposed over large areas and the surface profile requires leveling before the new coating system.
5. 5
   Control Joint Repair or Fill — Control joints (the intentional cuts in slabs) can be filled for a seamless finish or left open with flexible caulk depending on the slab's movement history and the homeowner's preference. We'll advise which approach is appropriate for your specific slab.
6. 6
   Coating Application — After all repairs have cured and the slab is diamond-ground to the correct profile, the coating system is applied — primer, base coat, flake or decorative layer, polyaspartic topcoat — exactly as with a new slab installation.

Common Concrete Repair Scenarios in Atlanta

Warranty in Detail

Concrete repair and coating completed in the same mobilization are warranted as an integrated system — the repair and the coating are both covered under our 15-year product warranty and 5-year workmanship warranty. The repair is not a separate lower-warranty item. What's not covered: new cracking that develops in areas outside the original repair scope due to ongoing slab movement or settlement events after installation. If your slab has significant structural movement, we'll note that in writing and discuss whether the coating project should wait until the underlying cause is addressed.
