Concrete crack repair comes first, before any coating goes down, since sealing over an active crack just lets it reappear through the new floor. Florence Epoxy Pros sees this most often on older slabs in and around Florence's historic core, as well as on rural-lot properties where caliche soil movement cracks workshop and garage floors over time.
The repair method depends on the crack: hairline cracks get filled with a flexible compound, while wider structural cracks need routing and a bonding agent before anything flexible goes on top. Florence Epoxy Pros classifies the crack first instead of treating every crack the same way.

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 on stable, non-moving cracks.
Polyurethane Crack Sealant
A flexible sealant accommodates slab movement without cracking again, a common choice on Florence's caliche-soil lots.
Semi-Rigid Repair Paste
A paste material fills narrow cracks while maintaining some flexibility for moderate settling.
Concrete Bonding Agent
A bonding agent ensures strong adhesion between old and new material on wider structural repairs.
Joint Filler Compound
A compound designed specifically for expansion and control joint repair on larger slabs.
Surface Patch Mix
A patch mix restores surface texture after crack repair so the coating applies evenly over the repaired zone.

DIY vs pro
DIY vs Hiring a Pro for Concrete Crack Repair
| DIY | Hire a pro |
|---|---|
| Hardware-store crack fillers are rigid and don't flex with slab movement, so they often re-crack within a season. | A pro classifies the crack first and matches it to a flexible or rigid filler based on actual movement, not guesswork. |
| A small, stable hairline crack with no active movement can sometimes be handled with a basic flexible caulk as a stopgap. | Professional crack repair preps the full crack length with debris removal and sometimes routing, which hardware fillers skip. |
| DIY repairs skip the classification step, so a structural crack can get treated like a cosmetic one and fail fast. | Repairs are leveled flush and sealed so the coating applied afterward doesn't telegraph the repair line. |

Concrete Crack Repair FAQs
Do I need to seal cracks before epoxy coating a workshop floor?
Yes. Coating over an unsealed crack just lets the crack show through, and often reopens, within the new finish.
Will epoxy crack if the concrete slab shifts with caliche soil?
A rigid repair or coating can re-crack with slab movement. A flexible polyurethane filler is usually the better match for Florence's soil conditions.
How much does concrete crack repair cost?
Small hairline cracks often run under $200 to repair, while longer structural cracks that need routing and bonding agent cost more depending on length and depth. A free estimate nails down the number.
How long does concrete crack repair take?
Most crack repairs cure within a day before a coating can be applied on top, though wider structural repairs may need longer.
Do I need a permit for concrete crack repair?
Cosmetic crack filling typically doesn't require a permit, but repair tied to a structural concern should be checked with Pinal County or the Town of Florence first.
