Why are cracks showing up on a slab that's barely a decade old? In Fountain Hills, the answer is usually heat cycling. Slab surfaces swing from well over 140°F in direct summer sun to much cooler desert nights, and that daily expansion and contraction opens hairline cracks over time, especially on original-build slabs from the town's earlier growth years.
Fountain Hills Epoxy Pros repairs cracks before any coating goes down, because a cracked slab under a new finish just telegraphs the same crack back to the surface within a season or two.

How Our Concrete Crack Repair Process Works
Step 1Crack Assessment
Measuring and classifying cracks to pick the right repair method for the movement involved.
Step 2Debris Removal
Clearing loose material and dust from the crack before any filler goes in.
Step 3Crack Widening
Slightly widening the crack so repair material has more surface area to bond to.
Step 4Filler Injection
Injecting or pouring compound into the void to fill it fully, not just skim the surface.
Step 5Surface Leveling
Leveling the repair flush with the surrounding slab so it won't show under a coating.
Step 6Final Sealing
Sealing over the repair to keep moisture out, important given Fountain Hills' monsoon season.
Materials
Materials and Methods for Concrete Crack Repair
Cracks that move with daily heat cycles need a different fix than a crack that's purely cosmetic, so we match the filler to how the slab is actually behaving.
Epoxy Crack Filler
A rigid bond for cracks that aren't actively moving, restoring structural integrity.
Polyurethane Crack Sealant
Flexes with the slab through Fountain Hills' daily heat swings without re-cracking.
Semi-Rigid Repair Paste
Fills narrow hairline cracks while keeping some give for minor movement.
Concrete Bonding Agent
Ensures the new repair material actually bonds to older, weathered concrete.
Joint Filler Compound
Used specifically on expansion joints that see the most thermal movement.
Surface Patch Mix
Restores texture after the crack is filled so the coating goes on smooth.

DIY vs Hiring a Pro for Concrete Crack Repair
| DIY | Hire a pro |
|---|---|
| Fine for hairline hairline cosmetic cracks in a low-traffic area with no plans to coat over them. | A crack that's actively moving with heat cycles needs a flexible filler, not a rigid surface patch, or it reopens within months. |
| Store-bought caulk-style fillers can hold for a season on cracks that aren't moving. | Fountain Hills Epoxy Pros widens and keys the crack before filling, which gives the repair material something to grip instead of just sitting on top. |
| — | Pro repair is done right before coating so the whole system bonds as one surface. |

Concrete Crack Repair FAQs
Can epoxy go over an existing cracked garage slab?
Not directly over an unrepaired crack. The crack needs to be filled and leveled first, or it will show through the coating and likely reopen.
Will epoxy crack in extreme Arizona heat?
A properly repaired slab with flexible crack filler underneath holds up well. The risk comes from coating over an unaddressed crack, which moves with the slab and cracks the finish above it.
How much does 1000 sq ft of epoxy cost?
Crack repair is usually priced separately from the coating itself, based on total crack length and severity rather than square footage of the room.
How long does Epoxy Flooring take?
Crack repair typically adds a day to the overall project timeline, since the filler needs to cure before grinding and coating proceed.
Do I need a permit for Epoxy Flooring?
Cosmetic crack repair ahead of a coating job usually doesn't need a permit. If cracks suggest a structural issue, that's a separate assessment outside our scope.
Is DIY Epoxy Flooring a good idea?
For cracks you plan to coat over, DIY surface patching without widening and keying the crack tends to fail within a season once heat cycling resumes.
