Chandler sits on expansive soil that shifts slightly with seasonal moisture changes, and newer slabs still settle for their first few years after the pour. That movement shows up as hairline cracks, and coating over a crack without repairing it first just locks the problem under a new layer that cracks again within a season. Chandler Epoxy Pros treats crack repair as a distinct step, not a corner to cut before the coating goes on.
Every crack gets classified before repair. A hairline settling crack takes a flexible filler, while a wider structural crack needs a different approach entirely, sometimes requiring a conversation before any coating work happens at all.

How Our Concrete Crack Repair Process Works
Step 1Crack Assessment
Each crack is measured and classified to pick the right repair method for its size and cause.
Step 2Debris Removal
Loose material and dust get cleared out before anything gets injected into the crack.
Step 3Crack Widening
Cracks get slightly opened along the edges so repair material has something to grip.
Step 4Filler Injection
A repair compound is injected to fill the void from the bottom up, not just skimmed over the surface.
Step 5Surface Leveling
The repair is leveled flush with the surrounding slab so it doesn't telegraph through a coating.
Step 6Final Sealing
A sealant goes over the repair to block moisture before any topcoat or coating is applied.
Materials
Materials and Methods for Concrete Crack Repair
Epoxy Crack Filler
Bonds rigidly for stable, non-moving cracks, restoring strength to the slab at that point.
Polyurethane Crack Sealant
Flexes with ongoing settling common in Chandler's newer-build subdivisions, so the repair moves with the slab instead of reopening.
Semi-Rigid Repair Paste
Fills narrow hairline cracks while keeping some give for minor seasonal shift.
Concrete Bonding Agent
Ensures the new fill material grabs onto the old concrete instead of sitting loose in the crack.
Joint Filler Compound
Used specifically on expansion joints that separate differently than a random slab crack.
Surface Patch Mix
Restores surface texture around the repair so it blends with the rest of the slab before coating.

DIY vs Hiring a Pro for Concrete Crack Repair
| DIY | Hire a pro |
|---|---|
| Store-bought concrete caulk can work on a single hairline crack in a low-traffic area. | Caulk doesn't flex with ongoing slab movement the way injected polyurethane or epoxy filler does, so DIY patches often reopen within a year. |
| Fine for a patio crack that isn't going under a coating system. | Cracks going under any epoxy, polyaspartic, or polyurea coating need proper repair first or the coating fails at that seam. |
| Cheap tubes handle cosmetic touch-ups where looks matter more than longevity. | Wider or recurring cracks may signal something structural that needs a real assessment, not a tube of filler. |

FAQs
Concrete Crack Repair FAQs
Can epoxy be applied directly over cracked concrete?
Cracks need to be repaired and sealed first. Coating over an unrepaired crack just traps the problem under the new surface, where it telegraphs through and reopens.
How much does crack repair cost in Chandler?
Pricing runs by linear foot of crack repaired, often bundled into a coating job. Standalone repair jobs typically range from a few hundred dollars for minor cracks to more for extensive repair work.
How long does crack repair take before coating can start?
Most crack repairs cure within a few hours to a day, depending on the filler used, before coating prep can begin.
Do I need a permit for crack repair?
Cosmetic crack repair generally doesn't require a permit. Structural cracks that affect the slab's integrity may need a separate engineering review, so flag those during your estimate.
Why does my crack keep coming back after I patch it?
Store-bought caulk and rigid patches don't flex with ongoing soil movement. A flexible polyurethane or polyurea filler is built to move with the slab instead of cracking again.
Will crack repair match the rest of my floor?
The repaired area gets leveled and textured to blend in, especially once it's covered with a color coat or flake system.
