Repair Methods
Foundation Crack Repair in Austin
The short answer
Foundation crack repair seals cracks with epoxy or polyurethane injection to stop water and air intrusion, typically costing $500–$1,500 per crack. Injection fixes the crack itself but not underlying movement — wide, growing, or horizontal cracks signal structural settlement that needs piers, not just sealant.

Not all cracks are equal
A crack is a symptom, not a diagnosis. The job of crack repair is twofold: seal the crack so water and air stay out, and figure out whether something bigger is moving underneath.
When sealing is the right call
If the crack is cosmetic — a thin vertical line from normal concrete curing or minor settling — injection is a clean, affordable fix. Epoxy bonds the concrete back together; polyurethane stays flexible to keep water out.
When it isn’t
Wide, horizontal, or stair-step cracks in brick usually mean active settlement. Sealing those without addressing the movement just delays the real repair. See the warning signs guide to tell the difference, and the cost guide for what a full correction runs.
Frequently asked questions
Which cracks are serious?
Horizontal cracks, stair-step cracks in brick or block, cracks wider than about 1/4 inch, and any crack that keeps growing are the ones to worry about — they usually mean active movement. Thin vertical cracks are often just curing or minor settling.
Does crack injection fix my foundation?
It fixes the crack, not necessarily the foundation. If settlement is pushing the foundation around, sealing the crack is a bandage — the movement will open it (or a new one) again. That's why diagnosis comes first.
