Last February I got a call from a Regent Park homeowner off Johnston Rd whose front walkway had settled a full two inches over about eight feet — from the porch step down to the driveway. She had tripped over the lip twice and was tired of pointing it out to guests. She had also gotten a quote from one of the big regional franchises to rip the walkway out and replace it — a five-figure job that would have taken a week and left her front yard torn up through spring. She wanted to know if there was a way to just lift the existing concrete back up. I met her at the front porch, checked the slab condition, probed the soil around the edges, and told her yes — this is a straight poly-injection lift.
Two days later I was there with a truck and a set of TerraThane 24024 canisters and lifted the walkway back to grade in about an hour and a half. Total on-site time including drilling, injection, and patch-and-seal was under three hours. She walked back and forth on it before we left. That job is the argument for poly lift versus tear-out and replace on a huge percentage of the Pineville subdivision stock — 90s and 2000s houses off Johnston Rd, Nations Ford Rd, and Park Rd where the front walks, driveways, garage aprons, patios, and pool decks were poured over compacted fill that has settled unevenly over two decades of Piedmont freeze-thaw and heavy Charlotte rainfall.
Historic Downtown Pineville is a different animal for concrete lifting because most of the pre-1930s houses on Main St and Polk St do not have concrete flatwork of any real size — the sidewalks are municipal, the walkways to the front porch are often original stone or brick pavers, and the driveways when they exist are short gravel or asphalt approaches to a detached garage. The concrete lifting work in Historic Downtown is almost entirely municipal sidewalk sections where a homeowner wants a trip hazard resolved on the walk in front of their property, or an accessory building slab like a garage apron where a mid-century pour has settled. The main event in Pineville concrete lifting is the subdivision belt — Regent Park, Providence Trace, and the newer builds off Johnston Rd where two decades of fill settlement have dropped walkways, driveways, garage aprons, and pool decks anywhere from a quarter inch to three inches out of plane.
What follows is what poly lift can and cannot do under Pineville concrete, when I recommend it over tear-out and replace, and when I tell an owner to bite the bullet and just replace the slab. Free on-site inspection with a level check and soil probe, fixed written quote before any drilling happens, no dollar surprises after we start injecting.
Inspection in Pineville is a fifteen-minute walk with a 6-foot straightedge, a laser level, and a soil probe. I put the straightedge across the settled area, measure the drop to the low point, check the transition points where the settled slab meets an adjacent structure — a porch step, a garage wall, a driveway approach — and probe the soil around the perimeter to get a sense of whether the fill under the slab is dry compacted material or wet clay that has been washing out through a drainage problem. That last one matters. If the settlement is being caused by an ongoing wash-out — a downspout dumping under the walkway, a broken irrigation line, a French drain that failed and is now steering water under the slab — poly lift will hold for a season or two and then the same slab will settle again. The drainage problem has to be fixed first or the lift is a temporary bandage.
On a Regent Park front walkway settlement job the sequence is: measure the drop at each pad joint, mark drilling locations on the slab surface (typically one hole per 4-foot by 4-foot section, offset from joints and edges), drill 5/8-inch injection ports through the slab, inject HMI TerraThane 24024 in controlled shots monitoring the slab with a laser level, walk the slab back to grade in overlapping passes, patch the injection ports with a color-matched concrete patch, and let the polyurethane cure. TerraThane 24024 reaches 90 percent of design strength in 15 minutes and full cure in 24 hours. Owner can walk the slab immediately, can drive on it after a few hours if it is a driveway, can put pool furniture back on a pool deck the next day.
Driveway lifting in the Regent Park and Providence Trace subdivisions off Johnston Rd is a bigger sequence because the pours are larger and the load requirement is higher. A residential driveway carries a car and sometimes a small truck, so the injection pattern is denser — one port per 4-foot by 4-foot section minimum, sometimes tighter along the tire tracks where the load concentrates. Sequence is the same but the material volume is higher and the lift takes longer to get right because the slab is heavier and more forgiving to over-lift correction than a walkway is.
Historic Downtown Pineville municipal sidewalk work — Main St, Polk St — requires town of Pineville permission and coordination because the sidewalks themselves are public right-of-way even when the homeowner is paying for the repair. We handle the coordination with the town. Accessory building slabs like a garage apron on a mid-century Nations Ford Rd property are straightforward homeowner work with no permit required as long as we are not modifying the structure above the slab.
What poly lift cannot do: crack repair. If the slab has structural cracks with vertical displacement, lifting the low side back to grade will not close the crack — the crack stays and now it is a lifted crack instead of a settled crack. On cracked slabs I recommend replacement, not lift. Poly lift also cannot fix a slab that is fundamentally too thin for its load — a 2-inch driveway pour that has cracked into a puzzle needs to come out and be replaced, not injected. Inspection tells us which situation we are in.
Material spec in Pineville is HMI TerraThane 24024 for residential walkway, driveway, garage apron, and patio lifting. TerraThane 24024 is a two-component structural polyurethane, closed-cell density around 4 pounds per cubic foot, compressive strength above 7,000 psf, reaches 90 percent design strength in 15 minutes, full cure in 24 hours. Injection through 5/8-inch ports drilled through the slab, patched with SikaCrete color-matched concrete patch after the lift. On pool decks around Regent Park and Providence Trace houses we use the same material but with tighter port spacing because the deck is thinner than a driveway and needs finer control on the lift. Injection guns are Alchemy-Spetec RH200 rigs pulling from 4-gallon canisters. Monitoring is a Leica L2P5G laser level set up on a tripod outside the work area with the receiver on a magnetic mount attached to the slab we are lifting. Real-time elevation readout so we know exactly when to stop injecting at each port.
On Historic Downtown sidewalk sections along Main St or Polk St, we coordinate with the town of Pineville public works before drilling because the sidewalks are municipal right-of-way. Material spec is the same TerraThane 24024. Patch material for municipal work uses a broom-finish concrete patch matched to the existing sidewalk texture so the repaired section blends. Accessory building slabs — mid-century garage aprons in the 1970s-80s Nations Ford Rd stock — same TerraThane spec, no permit required as long as we are not modifying the structure. If a slab has structural cracking with vertical displacement, we do not spec poly lift — we scope replacement because lifting a cracked slab does not close the crack. The compressive strength and cure time make TerraThane the right material for controlled residential lifting; other systems like sand-cement mudjacking work but are slower to cure and less controllable on tight lifts, which is why we do not use mudjacking on the Pineville subdivision stock.
Yes — Pineville is a regular concrete lifting route. Free on-site inspection anywhere in Pineville, fixed written quote before we touch anything.
Pineville concrete lifting is 80 percent Regent Park and Providence Trace subdivision flatwork — walks, driveways, garage aprons, pool decks poured over fill in the 90s and 2000s that has settled unevenly. Historic Downtown has almost no residential flatwork of significant size; the lifting work there is municipal sidewalk sections and accessory building slabs.

Lift it, most likely. Two inches of settlement on a walkway pour is squarely in the range where HMI TerraThane 24024 poly injection is the right call. Job is a couple hours on site — drill 5/8-inch injection ports, inject in controlled shots while a laser level monitors the slab elevation, walk the slab back to grade, patch the ports. You can walk on it immediately, full cure in 24 hours. Costs a fraction of tear-out and replacement and there is no torn-up yard to regrow. Free on-site inspection with a level check and soil probe to confirm the settlement is not being driven by an ongoing drainage problem — if it is, we fix that first.
No. Poly lift injects under the settled slab, not against the foundation wall. TerraThane 24024 expands controllably in the void under the slab and lifts the slab back to grade without applying lateral pressure to the foundation. The garage door threshold gets back to level, the water-runoff pattern at the garage door goes back to where it was designed to be, and the foundation is untouched. If your settlement is being caused by fill washing out under the slab through a drainage problem, we address the drainage at the same time — otherwise the fill keeps moving and the same slab will settle again in a few years.
Pool decks lift fine with poly. The slab is thinner than a driveway so the injection pattern is tighter — more ports, smaller volume per shot, slower monitoring — but the technique is the same. TerraThane 24024 works on pool decks specifically because it does not require excavation, does not put water or mud on the surrounding coping, and cures fast enough that pool furniture can go back on the deck the next day. Free on-site inspection to check the deck for cracks first — if the deck is already cracked with vertical displacement, we replace it instead of lifting because lifting a cracked slab does not close the crack.
Yes. Municipal sidewalks in Historic Downtown Pineville along Main St, Polk St, and the surrounding grid are public right-of-way, so the work requires coordination with the town of Pineville public works before we drill. We handle the coordination. The lift itself is the same TerraThane 24024 poly injection we use on residential flatwork. Municipal jobs get a broom-finish concrete patch on the injection ports matched to the existing sidewalk texture so the repair is not visible. Turnaround from inspection to on-site work is typically about a week factoring the town coordination step.
