Concrete Crack Repair, Leveling, and Resurfacing in San Diego
Not every concrete problem requires a full tear-out and replacement. SD Concrete Pros offers professional concrete repair services throughout San Diego County — fixing cracks, leveling sunken slabs, and resurfacing worn surfaces at a fraction of the cost of new concrete. Our repair work extends the life of your existing concrete by 10 to 15 years when done correctly.
We repair driveways, patios, sidewalks, garage floors, pool decks, and commercial concrete surfaces. If your concrete is structurally sound but cosmetically damaged, repair is almost always the smarter investment.
Concrete Repair Services
- Crack Repair: Epoxy injection for structural cracks, routing and sealing for surface cracks, and flexible sealant for expansion joint failures. We match repair color to your existing concrete.
- Slab Leveling (Mudjacking): Sunken concrete is lifted back to grade by injecting polyurethane foam or cementitious slurry beneath the slab. Fixes trip hazards and improves drainage without replacing the concrete.
- Resurfacing: A thin cementitious overlay (1/8 to 1/2 inch) applied over existing concrete to create a brand-new surface. Available in smooth, textured, stamped, or custom finishes.
- Spall Repair: Surface flaking and delamination repaired with polymer-modified patching compounds. Common on older San Diego concrete exposed to salt air.
- Expansion Joint Replacement: Old, compressed, or missing expansion joints removed and replaced with proper flexible backer rod and polyurethane sealant.
- Trip Hazard Removal: Diamond grinding of uneven slab edges — often required for ADA compliance on commercial properties and public sidewalks.
When to Repair vs. Replace
Not all concrete can be repaired. Here is how we evaluate your situation:
Repair is recommended when:
- Cracks are hairline to 1/4 inch wide and limited in number
- Settling is less than 2 inches and the slab is intact
- Surface damage is cosmetic (spalling, discoloration, rough texture)
- The slab is less than 20 years old with good structural integrity
- The sub-base is stable (no ongoing soil movement or tree root issues)
Replacement is recommended when:
- Large sections are broken into multiple pieces
- Settling exceeds 2 inches or is caused by ongoing soil issues
- Tree roots have lifted and cracked the slab extensively
- The concrete is over 30 years old and deteriorating throughout
- Drainage problems require regrading beneath the slab

Our Repair Process
- Inspection: We assess the type, location, and cause of damage. Understanding why the concrete failed prevents the repair from failing too.
- Root Cause: If tree roots, drainage issues, or soil settlement caused the damage, we address the underlying problem first.
- Preparation: Cracks are routed, surfaces are ground or shotblasted, and areas are cleaned for proper bonding.
- Repair: Materials are applied per manufacturer specifications with proper curing times between coats.
- Finishing: Repairs are color-matched and textured to blend with surrounding concrete as closely as possible.
- Protection: Sealer is applied over repaired areas for UV and moisture protection.
Frequently Asked Questions
Will the repair match my existing concrete color?
We use tinted repair materials and stains to match as closely as possible. An exact match is difficult because existing concrete has weathered over time, but with proper technique the repair blends well.
How long do concrete repairs last?
Properly done repairs last 10 to 15 years. Slab leveling typically lasts the remaining life of the slab. Resurfacing overlays last 8 to 15 years.
Can you fix concrete that has been previously repaired poorly?
Yes. We often correct failed DIY repairs and substandard contractor work. We remove the bad repair material, properly prepare the substrate, and redo it correctly.
