Phoenix slabs crack from the same thing every summer: extreme heat expansion followed by cool-night contraction, over and over, for years. A coating applied over an untreated crack just telegraphs that crack straight back through the finish within a season.
Phoenix Epoxy Elite treats cracks as their own repair step, not an afterthought bundled quietly into a coating quote. We assess the crack type, rout it out, and fill with a material that flexes with the slab instead of fighting it.

How Our Concrete Crack Repair Process Works
Step 1Crack Assessment
Cracks are measured and classified to determine the proper repair method.
Step 2Debris Removal
Loose material and dust are cleared from the crack before repair begins.
Step 3Crack Widening
Cracks are slightly widened to allow repair material to bond effectively.
Step 4Filler Injection
A repair compound is injected or poured into the crack to fill the void.
Step 5Surface Leveling
The repaired area is leveled flush with the surrounding concrete surface.
Step 6Final Sealing
A sealant is applied over the repair to prevent moisture intrusion.
Materials
Materials and Methods for Concrete Crack Repair
Epoxy Crack Filler
A rigid epoxy filler bonds tightly to restore structural integrity to cracks that aren't actively moving.
Polyurethane Crack Sealant
A flexible sealant accommodates slab movement without cracking again, which matters most on Phoenix slabs cycling through extreme heat swings.
Semi-Rigid Repair Paste
A paste material fills narrow cracks while maintaining some flexibility, a middle option between rigid and fully flexible fillers.
Concrete Bonding Agent
A bonding agent ensures strong adhesion between old and new material.
Joint Filler Compound
A compound designed specifically for expansion and control joint repair.
Surface Patch Mix
A patch mix restores surface texture after crack repair is complete.

DIY vs Hiring a Pro for Concrete Crack Repair
| DIY | Hire a pro |
|---|---|
| Store-bought crack filler works fine for hairline cosmetic cracks not under a coating | Flexible fillers matched to the crack type and whether a coating is going on top |
| Fine for small, stable patio cracks with no plans to coat over them | Proper routing widens the crack correctly so the filler actually bonds |
| Risk: rigid fillers don't flex with Phoenix heat cycling and often fail within a season | Structural or foundation-related cracks get flagged before they become a bigger problem |
| Risk: a crack that's actively growing needs assessment a retail product can't give you | Repair holds up under a coating instead of telegraphing back through within months |

FAQs
Concrete Crack Repair FAQs
Do I need to fix cracks before epoxy coating?
Almost always. A coating applied over an untreated crack will crack again in the same spot within a season as the slab keeps moving underneath it.
How much does concrete crack repair cost in Phoenix?
Cost depends on crack length and severity. Minor cracks cost less to fill than long structural cracks. It's often bundled into a coating job at a lower combined rate.
Do I need a permit for crack repair?
Cosmetic crack repair usually doesn't need a permit. Cracks tied to structural or foundation issues may require inspection, which we'll flag if we see it.
Why does Phoenix concrete crack so much?
Extreme summer heat expansion followed by cooler night contraction puts constant stress on slabs over the years, which is why flexible repair materials matter here specifically.
Can I use caulk instead of a proper crack filler?
Caulk isn't built to bond with concrete or handle foot and vehicle traffic. It fails fast and doesn't give a coating anything solid to adhere to.
How long does crack repair take before I can coat the floor?
Most filler needs to cure for a few hours to a day before coating can proceed, depending on the product and crack size.
