A cracked slab under a new coating is a problem waiting to come back. If the crack isn't repaired properly, it telegraphs right through the fresh epoxy within a season or two as the concrete keeps moving.
Marana Epoxy Pros treats crack repair as its own step, not an afterthought before coating. Older rural slabs out toward Picture Rocks and Avra Valley especially need this done right, since years of heat cycling have usually widened hairline cracks that look small on the surface but run deeper than they appear.

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, suited to hairline cracks on stable slabs.
Polyurethane Crack Sealant
A flexible sealant accommodates the slab movement that Arizona's heat swings cause, without cracking again.
Semi-Rigid Repair Paste
A paste material fills narrow cracks while keeping some flexibility for moderate movement.
Concrete Bonding Agent
A bonding agent ensures strong adhesion between old and new material, important on weathered older slabs.
Joint Filler Compound
A compound designed for expansion and control joints that see regular seasonal movement.
Surface Patch Mix
A patch mix restores surface texture once the crack repair is complete.

DIY vs Hiring a Pro for Concrete Crack Repair
| DIY | Hire a pro |
|---|---|
| Hardware-store caulk tube fillers work for cosmetic hairline cracks you don't plan to coat over | Flexible polyurea or epoxy fillers actually move with the slab instead of popping loose |
| Fine for a quick touch-up on a crack with no plans for a topcoat | Proper routing widens the crack first, something caulk tubes skip entirely |
| Risky for anything load-bearing or wider than a hairline | Needed before any coating goes down, since a failed DIY fix usually means redoing both the repair and the coating |

Concrete Crack Repair FAQs
Will epoxy crack if my garage slab already has hairline cracks?
If the crack isn't repaired with a flexible filler first. Rigid fillers or skipping repair altogether lets the crack telegraph through the new coating.
Can epoxy be applied over a concrete slab with moisture issues?
Crack repair and moisture checks often happen together. Cracks can be an entry point for moisture, so we address both before any coating starts.
How much does concrete crack repair cost?
Cost depends on crack length, depth, and how many cracks need attention. A single hairline crack costs far less than repairing a slab with several wider cracks.
Does crack repair mean the same crack won't come back?
A flexible filler reduces the chance significantly, since it moves with the slab instead of fighting it. No repair is permanent against ongoing structural settling, but most cosmetic cracks don't return.
When should I get cracks repaired before getting a coating quote?
Any time you see visible cracking, before scheduling a coating estimate. We can assess during the same visit, so one call covers both.
