Why Choose Our Crack Repair
We diagnose the cause of cracking before recommending repairs. Understanding whether cracks result from settling, heaving, overloading, or shrinkage determines the correct repair method.
Our crack repair methods are matched to the crack type — structural cracks get epoxy injection for strength, moving cracks get flexible sealant, surface cracks get routing and filling.
Early crack repair prevents expensive problems. A $300 crack repair today can prevent a $5,000+ slab replacement next year.
Signs You Need Crack Repair
1. Cracks wider than hairline
Cracks that you can fit a credit card into are wide enough to allow significant water infiltration and will worsen with freeze-thaw cycles.
2. Water leaking through foundation cracks
Active water leaks through basement wall or floor cracks need injection repair to stop water entry and prevent further deterioration.
3. Cracks with vertical displacement
When one side of a crack is higher than the other, it indicates structural movement that needs evaluation and repair.
Our Crack Repair Process
Step 1 — Crack Assessment
Measure crack width, depth, and direction. Determine if the crack is structural, shrinkage, or settlement-related.
Step 2 — Surface Preparation
Clean the crack of debris, dirt, and loose material. For injection: install injection ports along the crack.
Step 3 — Repair Application
For injection: pump epoxy or polyurethane under pressure to fill the crack. For routing: widen the crack and fill with sealant.
Step 4 — Surface Restoration
Smooth and blend the repair to match surrounding concrete as closely as possible.

FAQs About Crack Repair
Can cracked concrete be repaired or does it need replacement?
Most cracks can be effectively repaired if caught early. Replacement is recommended when cracks are extensive (covering 30%+ of the surface), show severe displacement, or the concrete is heavily deteriorated with spalling and delamination.
Will the crack come back after repair?
Properly repaired cracks typically stay sealed. Epoxy injection creates a bond stronger than the original concrete. If the underlying cause (settling, drainage, tree roots) isn't addressed, new cracks may develop nearby.
