Charleston concrete leveling and slab-lift jobs typically invoice $600 to $6,500, with downtown peninsula tidal-shift voids and large pool-deck lifts in Mount-Pleasant-adjacent neighborhoods pushing toward the high end. SCConcreteLift is a South Carolina scheduled-inspection directory for polyjacking and mudjacking — call PHONE to book an on-site assessment with a licensed SC LLR-credentialed contractor serving the Charleston peninsula, West Ashley, James Island, Johns Island, Daniel Island, and Folly Beach across ZIPs 29401, 29403, 29407, and 29412.
How the referral works in Charleston
SCConcreteLift does not pump foam, drill injection holes, or pour cement slurry. We do not employ pumping crews and we do not hold any SC LLR Residential Builder or General Contractor license. We operate a pay-per-call dispatch directory. When a Charleston homeowner calls the number on this page, the call routes through our affiliate network to an independent contractor licensed under SC Code Title 40 to perform residential concrete leveling work in Charleston County. The contractor schedules a daytime on-site inspection — usually within five business days — and provides a written quote before any work begins; you pay the contractor directly. South Carolina is a one-party consent state for call recording under SC Code Ann. § 17-30-30, but our network’s IVR provides recording disclosure at call connection as standard policy.
What our Charleston network contractors handle
- Sunken driveway and walkway slabs on the West Ashley and James Island sandy substrate where downspout washout has carried fines out from under the slab
- Pool deck settling on the saltwater-side coping at homes facing the Ashley and Cooper Rivers, where tidal water-table rise and fall accelerates fines migration
- Stoop and front-porch separation on the historic peninsula where pier-and-grade-beam foundations sit alongside post-1950 slab additions
- Garage floor pitch correction on West Ashley and Mount Pleasant ranches where the slab has dropped 1–3 inches toward the foundation, sending water into the wall plate
- Trip-hazard offset at sidewalk and patio joints in older neighborhoods such as Wagener Terrace, Hampton Park Terrace, and Old Village
- Polyjacking under HVAC condenser pads that have settled out of level, threatening line-set integrity
- Void-fill under interior slab-on-grade where a leaking copper supply line has eroded base material before being detected
- Pre-listing trip-hazard correction on Charleston peninsula short-term-rental properties where ADA-style threshold offsets surface during inspection
Typical cost in Charleston
A Charleston concrete lift project typically runs $600 to $6,500. A single 4’×4’ driveway slab polyjack runs $400–$900. A two-car driveway lift runs $1,200–$2,800 depending on void volume. Pool-deck lift on Daniel Island or Mount-Pleasant-adjacent properties is $1,800–$5,500 depending on coping detail. Garage-floor pitch correction averages $1,500–$3,500. Mudjacking (cement slurry) for the same projects runs roughly 25–35% lower per cubic foot but requires a 24-hour cure and leaves a moisture-sensitive grout that the Charleston coastal humidity does not flatter. Polyjacking (closed-cell polyurethane foam) typically wins on smaller residential jobs because the foam is waterproof, walkable in 15 minutes, and drivable in 30. Cost figures aggregated from HomeAdvisor and regional Carolinas franchise published price ranges.
Charleston soils and why slabs settle here
The Charleston peninsula and the surrounding tidewater communities sit on a layered profile of marine-terrace sand, organic peat lenses, and re-deposited fill from centuries of waterfront construction. Three things drive Charleston slab settling: tidal groundwater rise and fall that flushes fines out of the bedding, downspout and irrigation discharge that scours base material, and old plumbing leaks under interior slabs that void out before the homeowner notices. Polyjacking is preferred over mudjacking in Charleston because the polyurethane foam doesn’t absorb moisture and doesn’t add weight to substrate that’s already marginal. For settlement greater than 3 inches, or where the slab is structurally tied to the home’s foundation rather than free-floating, a licensed SC professional engineer should be involved before lifting begins.
How to choose a Charleston concrete contractor
- Verify the contractor’s SC LLR license at verify.llr.sc.gov (Residential Builder for residential work, General Contractor for larger commercial)
- Confirm general liability insurance ($1M minimum) and workers’ compensation; ask for a current certificate of insurance
- Ask whether the bid is polyfoam or mudjacking, and why — both have legitimate uses; a contractor who only offers one method may not be giving you the right answer
- Get a written flat-rate or per-square-foot quote before injection holes are drilled
- For pool decks, ask whether the contractor patches and color-matches the injection holes, or whether you need a separate concrete finisher
- Save before-and-after elevation measurements and dated photos for the SC residential property condition disclosure if you sell within 24 months
