Cracks in a concrete slab don't go away under a coat of epoxy, they telegraph right through it within a season or two. El Mirage Epoxy Pros repairs active and hairline cracks before any coating gets applied, which matters most on El Mirage's older pre-2010 homes where soil movement has left more cracking than newer construction nearby.
Crack repair here uses flexible filler material matched to the type and size of crack, not a generic caulk bead. The goal is a repair that moves with the slab instead of reopening the same crack line a year later.

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
Not every crack needs the same filler, which is why El Mirage Epoxy Pros matches material to crack type.

Epoxy Crack Filler
A rigid epoxy filler bonds tightly to restore structural integrity to cracks that aren't actively moving.

Polyurethane Crack Sealant
A flexible sealant accommodates slab movement without cracking again, a common need on older El Mirage slabs with ongoing settling.

Semi-Rigid Repair Paste
A paste material fills narrow cracks while maintaining some flexibility for hairline surface cracking.

Concrete Bonding Agent
A bonding agent ensures strong adhesion between old and new material.

Joint Filler Compound
A compound designed specifically for expansion and control joint repair.

Surface Patch Mix
A patch mix restores surface texture after crack repair is complete.

DIY vs Hiring a Pro for Concrete Crack Repair
| DIY | Hire a pro |
|---|---|
| Caulk-tube crack fillers from a hardware store can patch very minor hairline cracks temporarily | A pro routes the crack first, widening it slightly so filler actually bonds instead of sitting on the surface |
| Risk: these products don't bond deeply or flex with the slab, so the same crack often reopens within months | Flexible polyurethane or epoxy fillers are matched to crack type, something a one-size-fits-all tube product can't do |
| Not suitable for active, widening, or structural cracks | Proper repair prevents the crack from telegraphing through a new epoxy coating later |

FAQs
Concrete Crack Repair FAQs
How much does concrete crack repair cost in El Mirage?
Most jobs run $150 to $2,000 depending on how many cracks there are and their severity.
How long does concrete crack repair take?
A day for the repair itself, with filler cure time ranging from several hours to overnight before coating can proceed.
Do I need a permit for concrete crack repair?
Standard cosmetic crack repair doesn't require one. Structural cracks tied to foundation issues may need review.
Will epoxy crack if my concrete slab already has cracks?
Uncoated cracks typically telegraph through a new coating within a season or two. Repairing them first prevents that.
What's the cheapest way to fix a cracked garage floor before epoxy?
Routing and filling hairline cracks with a flexible sealant is the most cost-effective fix, cheaper than full leveling when the floor isn't uneven.
Is DIY concrete crack repair a good idea?
Only for very minor hairline cracks as a temporary measure. Hardware-store caulk fillers don't bond or flex like a proper repair and often fail again.
What affects concrete crack repair pricing?
Linear footage of cracking, how many separate cracks exist, and whether the damage is cosmetic or structural.
What's typically included in concrete crack repair?
Assessment, debris removal, crack routing, filler injection, surface leveling, and a final seal coat.
