Sunken on the sand? Often it lifts back. Cracked through? We'll tell you
Foam lifting puts a sunken driveway apron, walk panel or pool deck section back where it was for a fraction of replacement — when the slab is sound. When it isn't, we say so.
Concrete on the Grand Strand sinks more than it cracks. The sand under a slab washes out over the utility trench, the ditch backfill or the pool backfill, and the slab follows it down — a dropped apron at the street, a walk panel with a lip, a pool deck corner that tips toward the house, a garage floor that's settled at the door. If the concrete itself is sound, the fix is to lift it: we drill a pattern of small holes, inject a two-part polyurethane foam that expands under the slab, fill the void and raise the slab back to grade in minutes, then patch the holes. It's done in a morning, you can drive on it the same day, and the foam doesn't wash out the way the sand did. It's a fraction of the cost of replacement and it's what most 1970s–90s driveways in the city need.
What lifting can't fix: a slab that's cracked into pieces (the pieces lift separately), a slab that's spalling from rusting steel inside it (the rust keeps going), a slab that's too thin or was poured badly, or an apron inside the City of Myrtle Beach that's below the current six-inch spec. Those get replaced. Cracks get sorted the same way — hairline shrinkage cracks are cosmetic and get sealed; working cracks that are moving or offset mean the slab is settling and get lifted or replaced; spalling and scaling get patched with a polymer-modified mortar if the cause is surface wear, or replaced if the cause is rust. Steps, stoops and curbs get formed and patched. We'll give you the honest side of the line on every one.
What's included
Foam lifting
Polyurethane injected under the slab to fill the void and lift it to grade; drive on it the same day.
Sound-the-slab honesty
Cracked-through, rust-spalling or under-spec slabs get a replacement price, not a lift that won't hold.
Crack repair
Routed and sealed with a flexible filler; epoxy injection for structural cracks on a slab worth saving.
Spall and scale patching
Polymer-modified mortar for worn surfaces, steps, stoops and curbs.
Trip-hazard grinding
Small lips between panels ground flush when lifting isn't warranted.
Drainage fixed too
The downspout or the ditch that caused the washout gets addressed so the slab stays up.

Questions we get about concrete repair and leveling
How much does it cost to level a driveway in Myrtle Beach?
Foam lifting a sunken apron or a section typically runs $600–$1,800, and a whole driveway with several low spots $1,500–$3,500 — against $4,000–$6,500 to replace a two-car driveway. If the slab is sound, lifting wins; if it's cracked through, replacement does.
Will the slab sink again?
Not for the same reason — the foam fills the void and doesn't wash out like sand. If the cause was a leaking downspout or a failed ditch pipe and that's not fixed, water will find a new path, which is why we address the drainage too.
Can you lift a pool deck without damaging the pool?
Yes — the injection holes are in the deck, not the shell, and the lift is controlled in small increments. A deck that's tipped toward the pool because the backfill settled is the classic foam-lift job.
Can you fix a cracked slab without replacing it?
If the crack isn't moving and the slab is level, sealing it is fine and the slab will last. If one side is higher than the other or the crack is widening, the slab is settling and sealing it just hides the symptom; it needs lifting or replacement.
