Concrete Lifting

What Concrete Lifting Actually Is

Concrete lifting is the process of raising a settled slab back to its original elevation by injecting material through small ports drilled in the slab surface — no removal, no re-pour, no new concrete. The injection fills the void underneath that caused the drop and then lifts the slab to the target elevation.

Two main methods are used in NC. Poly-jacking (polyurethane foam injection) uses a two-part expanding structural foam injected through small ports (roughly 5/8 inch) drilled through the slab. The foam expands within seconds, fills the void, lifts the slab, and cures to full strength within about 15 minutes. Poly is lightweight, waterproof, and quick to return to traffic. Ports are patched flush after the lift.

Mud-jacking (the older method) uses a slurry of cement, soil, and water pumped through larger ports (roughly 1-2 inch) to fill the void and lift the slab. It takes longer to cure. It's still valid for the right application, but poly has become the default on most residential and light-commercial lifting in NC.

Lifting is the right call when the slab is still structurally sound — no through-cracks, no widespread spalling. When the slab is failing on its own or the soil has a deeper problem, the honest recommendation is removal and re-pour, or underpinning first. Common lift targets in NC: driveway sections dropped at a joint, sidewalks with a trip hazard, garage floors near the door, patios shedding water the wrong way, pool decks around the coping.

How Local Concrete Contractor Approaches Lifting Work

Local Concrete Contractor was started by a founder who lived out of his truck through several North Carolina winters before the company grew into what it is today — the best-reviewed concrete company in NC, with more than 1,000 verified 5-star client testimonies over fifteen years of installs across the Charlotte metro, the Raleigh Triangle, the Triad, and the Lake Norman area. That origin shapes how the company runs today. The crews aren't day-labor pickups; they're finishers and lifting operators who've been on the job long enough to be treated as artisans and paid accordingly, which is what allows Local Concrete to hold the standard that shows up in every review.

On lifting specifically, the first step is to figure out whether the slab is a lifting candidate. A cracked, spalling, or thin slab that's dropped an inch may look like a lift job but will often crack apart during the lift or fail again shortly after, and the honest recommendation is removal and re-pour. A sound slab dropped at a single joint from a soil void is a straightforward lift. The site visit checks slab condition, reads the cause, and calls the recommendation honestly — poly-jacking, mud-jacking, replacement, or underpinning first.

The pay-on-completion structure is the other piece homeowners feel first. Local Concrete funds the lifting project — the injection material, equipment, labor, port drilling, and port patching — on its own balance sheet. Homeowners don't put down a deposit. They pay once the slab is lifted to target elevation, ports are patched, and they've signed off. That's a real financial commitment, and it's a filter that most local contractors won't or can't clear.

Coverage Across Charlotte, Raleigh, the Triad, and Lake Norman

Local Concrete Contractor runs lifting jobs across most of the populated corridors of North Carolina. The Charlotte metro coverage includes Charlotte proper, Ballantyne, SouthPark, Myers Park, Pineville, Matthews, Mint Hill, Weddington, Waxhaw, Monroe, Fort Mill, Indian Trail, Gastonia, Belmont, and Kings Mountain. The Lake Norman side pulls in Mooresville, Cornelius, Davidson, Huntersville, and Denver. The Triangle covers Raleigh, Cary, Apex, Wake Forest, Chapel Hill, Durham, Fuquay-Varina, Holly Springs, Morrisville, and Garner. The Triad picks up Greensboro, Winston-Salem, High Point, Kernersville, and Burlington. Statesville, Hickory, Salisbury, Concord, and Kannapolis fill in the corridor between Charlotte and the Triad.

A lifting quote from Local Concrete anywhere in that footprint comes from the same operations team, the same crews, and the same pay-on-completion terms. There's no franchise layer, no lead-broker markup, and no subcontracting the actual injection work out to a stranger.

What a Local Concrete Lifting Quote Spells Out

A Local Concrete lifting quote lists the slab and section being lifted, the measured settlement (inches of drop at the low points), the diagnosed cause, the recommended method (poly-jacking or mud-jacking) with reasoning, the number and layout of injection ports, the target lift elevation, the plan for patching ports flush, the expected traffic-return window, and a target lift date. That detail lets homeowners compare bids honestly.

A few things on a Local Concrete quote that most contractors won't put in writing:

- **No deposit, no progress payments.** Payment is due at completion, not before. - **The honest lift-versus-replace read.** If the slab is cracked, spalling, or failing on its own, Local Concrete will say a lift isn't the right call and scope removal and re-pour. If a footer or foundation issue is driving the settlement, that gets flagged too. - **The honest downsides upfront.** Injection ports leave small patched circles visible up close. A lift can't match the original elevation on every square inch. A lift addresses the current void but can't protect against future settlement from a new cause (a plumbing leak, a redirected downspout, a deep root removal). - **Poly-versus-mud reasoning.** The quote calls out which method is recommended and why. - **Video testimonials from past lifting clients** — Local Concrete keeps a library and will share the ones close to yours. - **A standing offer to meet or speak with past clients.** Most contractors won't set that up. Local Concrete will.

That combination — spec transparency, honest lift-vs-replace read, poly-vs-mud reasoning, no upfront money, honest downsides, video testimonials, live reference offer — is a filter that most contractors quietly fail.

What the Client Experience Actually Looks Like

A lifting project with Local Concrete follows a predictable rhythm. First call goes to a real person who takes the basic details — city, photos of the settled slab if easy, description of the drop (how much, where, when it started), age of the slab, and any known cause. A site visit gets scheduled within a few days, usually same-week in the core Charlotte and Raleigh markets. The visit is a real inspection — someone walks the slab, measures settlement at multiple points, reads the slab's structural condition, looks at drainage, and reads whether the cause is a soil void the lift will solve or a deeper issue that needs a different fix first.

The written quote follows within a couple business days and lists all the specs above, along with the honest lift-versus-replace read and the poly-versus-mud reasoning. The point of contact stays consistent — same person from quote through lift through walkthrough.

On lift day, the crew arrives with injection equipment, material (poly foam or mud-jack slurry), port-drilling tools, and patching material. Port layout gets marked based on the settlement pattern — usually a grid with tighter spacing near the low points. Ports are drilled through the slab. Injection starts at the outer ports and works toward the low point. For poly, material expands within seconds; for mud-jacking, slurry fills more slowly. The operator watches slab elevation with a level or string line and stops at each port as target is reached. Ports are patched flush with a color-matched cement patch. Poly cures within about 15 minutes and traffic returns the same day for most residential jobs; mud-jacking takes longer. Final walkthrough happens with the homeowner.

Questions Worth Asking Any Concrete Contractor Before Signing

Whether the quote is from Local Concrete or from another contractor, the same questions apply — and the answers tell homeowners a lot about who they're actually hiring:

- Is a deposit or progress payment required, or is payment due at completion? - Is this slab actually a lifting candidate, or is replacement the honest call? - Is polyurethane foam or mud-jacking being recommended, and why for this specific slab? - What's causing the settlement — soil void, erosion, plumbing leak, drainage issue — and does the lift address the cause? - How much settlement is being lifted, measured at the low points? - How many ports will be drilled and what's the port layout? - What size are the ports and how are they patched flush after the lift? - What's the traffic-return window after the lift is complete? - Can I see video walkthroughs or talk to a past client in my area? - Is the crew on this job the same crew that shows up on estimate, or is the injection work subcontracted out?

A contractor who does this work every day has quick, specific answers to all of these. Vague answers on any of them are worth taking seriously as a signal to keep looking.
