Desert heat swings hard between day and night here, and concrete expands and contracts right along with it. That movement is exactly what causes hairline cracking in garage and patio slabs across Green Valley, especially on older concrete.
Green Valley Epoxy Pros repairs those cracks before any coating goes down. A coating applied over an unrepaired crack usually just shows that same crack back through the surface within a season or two.

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.

DIY vs hiring a pro for Concrete Crack Repair
| DIY | Hire a pro |
|---|---|
| A caulk-tube crack filler can work for cosmetic, non-structural hairline cracks | Routing the crack open so filler actually bonds is the mechanism a caulk tube skips entirely |
| Fine for a quick patch before selling a property, not a long-term fix | Correct filler choice (rigid vs flexible) based on whether the crack is still moving |
| Risk of the filler not bonding if the crack isn't cleaned out properly first | Expansion joint work done alongside crack repair so the whole slab is addressed at once |

Concrete Crack Repair FAQs
Will epoxy crack if my slab has hairline cracks already?
If the crack isn't repaired first. Any coating applied directly over an unaddressed crack typically shows that crack again within a season as the slab keeps moving.
Do I need to seal expansion joints before coating a patio slab?
Yes. Expansion joints move with temperature swings, and sealing them before coating prevents that movement from cracking the finish along the joint line.
What's the cost for concrete crack repair?
Pricing runs by linear footage and crack severity. Minor hairline cracks cost less to route and fill than wider, structural-leaning cracks needing more material.
Do I need a permit for crack repair?
Cosmetic hairline crack filling generally doesn't need a permit. Cracks tied to structural settling or larger slab movement may require Pima County review, so flag anything that looks more serious than surface cracking.
How long does crack repair take before coating can start?
Filler typically cures within a day, after which coating prep can begin on the repaired area.
