A crack in your garage or patio slab doesn't stay the same size through a San Luis summer. The concrete expands under 110°F heat and contracts again overnight, and that daily cycle widens a hairline crack into a real problem faster than it would in a milder climate. Any coating applied over an untreated crack will telegraph that movement right through the new surface within a season.
San Luis Epoxy Pros repairs cracks before any epoxy, polyaspartic, or polyurea coating goes on.

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 filler bonds tightly for cracks that aren't actively moving, restoring structural integrity.
Polyurethane Crack Sealant
A flexible sealant accommodates the daily expansion and contraction typical of San Luis slabs.
Semi-Rigid Repair Paste
Fills narrow cracks while allowing some movement without breaking the seal.
Concrete Bonding Agent
Ensures the repair material bonds tightly to the original slab edges.
Joint Filler Compound
Used specifically on expansion and control joints that see the most seasonal movement.
Surface Patch Mix
Restores surface texture around the repair so it blends into the surrounding concrete.

DIY vs hiring a pro for Concrete Crack Repair
| DIY | Hire a pro |
|---|---|
| Fine for a single hairline crack in a low-traffic area with no plans to coat over it soon. | Needed before any coating, since a filler that isn't flexible enough won't hold up to slab movement and will telegraph through the new coat within a year or two. |
| Hardware-store crack filler can work as a short-term cosmetic fix. | Recommended for cracks that are spreading, widening, or showing vertical offset. |
| Reasonable for patching a small crack you plan to monitor, not coat. | Worth it for multiple cracks or cracks near door frames, where repair needs to match the right flexibility to the type of crack. |

FAQs
Concrete Crack Repair FAQs
Can epoxy be applied directly over a cracked slab?
Cracks need to be filled and stabilized first; coating over an untreated crack almost always results in the crack showing through the new surface.
How much does crack repair cost in San Luis?
Cost depends on the number, length, and depth of cracks; a few small cracks cost much less than a slab with extensive cracking throughout.
Does crack repair add time before coating can start?
Repaired cracks need to cure before coating work begins, typically adding a day or so to the overall project timeline.
Will a repaired crack come back?
A properly matched flexible filler should hold through normal slab movement, though very active structural cracks may need monitoring over time.
Is DIY crack filler a long-term fix?
Hardware-store fillers often aren't flexible enough to handle the heat-driven expansion and contraction seen in this climate, so they tend to fail again within a year or two.
