Slab Repair & Concrete Leveling in Mobile, AL
Concrete doesn't sink because the concrete failed — it sinks because the ground under it did. Washed-out fill, poorly compacted soil, and years of Gulf Coast rain leave voids, and the slab settles into them: a driveway section drops at the garage, a sidewalk panel becomes a trip hazard, a patio tilts toward the house and sends rainwater at the foundation.
We lift settled concrete back into place by pumping expanding polyurethane foam through dime-sized holes. It fills the void, raises the slab within minutes, and cures the same day — at a fraction of the cost of tearing out and repouring. We also repair and stabilize cracked interior slab floors and can tell you honestly when a slab is too far gone and replacement is the better spend.

How it works
Send a photo or describe it
A picture of the settled section usually gets you a ballpark on the first call.
On-site measure
We check how far it's dropped, probe for voids, and confirm foam lifting is the right fix.
Exact written price
Priced by the job, not by surprise. Approve it before we schedule.
Drill, pump, done same day
Small holes, foam injection, controlled lift, holes patched. Drive on it the same day.
Why concrete sinks so fast here
Mobile's rain does two things to the ground under concrete: it washes fine soil out from under slab edges, and it saturates fill until it compresses under load. Downspouts that discharge next to a driveway, gutters that overflow onto a patio, an irrigation leak under a walkway — give any of them a few seasons and the slab above starts to drop.
Foam lifting fits this climate for a practical reason: it's waterproof. The old mudjacking slurry could wash out again in the same conditions that caused the settlement; cured polyurethane doesn't. Pair the lift with fixing the water source — often a simple downspout extension — and the repair holds.
Slab & Concrete Leveling questions
How much does concrete leveling cost?
Most residential lifting jobs — a couple of driveway or sidewalk sections — run $500–$1,500 here, larger multi-slab jobs more. That's typically a third to half the cost of tear-out and repour, and there's no week of curing or ruined landscaping.
Foam lifting vs. mudjacking — which do you use?
Polyurethane foam. It lifts with smaller holes, cures in minutes instead of days, weighs almost nothing so it doesn't re-compress the soil, and doesn't wash out in our rain. Mudjacking is cheaper per job but doesn't hold up as well in this climate.
My interior slab floor dropped — is that the same repair?
Often yes: interior slabs over settled fill can be foam-lifted the same way, working through the finished floor with small penetrations. If the drop is caused by foundation-level settlement rather than a local void, we'll tell you — that's a pier job, and we do those too.
