Concrete lifting in Belmont is a smaller share of my work than crawlspace and drainage — most of Belmont's building stock is frame on brick or block foundation, not slab-on-grade — but when it comes up it is almost always driven by the same two things: fill-dirt settlement in the 2000s-era subdivisions off S Point Rd, or long-term erosion along the Catawba River side of downtown. Last May I got called out to a 2006 house in McLean where the homeowner had a driveway approach that had settled a solid inch and a half over four years, right where it meets the garage slab. Every time she pulled the SUV in, the front tires would drop off the lip and it was starting to crack the driveway concrete a foot back from the joint. That is a fill-dirt settlement job. The developer had brought in fill to level the lot when they built the house, the fill compacted differentially over the decade, and the driveway approach dropped with the fill because it was poured over the disturbed dirt while the garage slab sat on the original grade.
Poly foam injection — HMI TerraThane 24024 is the material we spec — was the right call there. Drilled 5/8-inch injection ports every 18 inches along the settled section, staged three separate lifts to avoid over-injecting on any one shot, brought the approach back to level within a quarter inch of the garage slab, patched the ports with matching color-tinted mortar. Same afternoon, drivable in two hours, and the fill underneath is now stabilized with a rigid foam matrix that will not re-settle the way raw dirt will. That is the McLean and Reflection Pointe story on repeat — 2000s builds where fill dirt was part of the original construction and settlement is showing up now.
The other Belmont concrete lifting job I get is stoops, sidewalks, and porch slabs on the mill village houses downtown where a century of tree root pressure, freeze-thaw at the 6-to-8-inch depth, and adjacent foundation settlement has moved a slab an inch or two off level. Those are mostly cosmetic and safety fixes — trip hazards on the front walk, a porch stoop that has tilted enough to shed water back toward the house instead of away from it. Poly injection is the right tool for most of them too, though occasionally on a small porch stoop the honest answer is demo and repour rather than lift, and I will tell you that on the inspection.

Every Belmont concrete lifting inspection starts with figuring out what actually caused the settlement, because the answer changes whether poly injection is the right tool or whether we should be doing something else first. On the 2000s subdivision side — McLean, Reflection Pointe, the newer builds off S Point Rd toward the Cramerton line — fill-dirt settlement is the default assumption and I confirm it by looking at the settlement pattern. Fill settlement gives you a clean drop right where the fill area meets the original grade, usually along a driveway approach, a garage slab-to-driveway transition, or a walkway where it leaves the porch. If the drop is at a specific transition and the rest of the slab is level, that is fill.
On the mill village side downtown — Main St, Central Ave, Woodlawn Ave, Catawba St — the settlement pattern is different. Century-old walks and porch stoops were poured directly on grade with minimal or no base prep, and they have moved for three separate reasons over the decades. Root pressure from mature oaks and maples in the historic core is the biggest one. Freeze-thaw cycling at the 6 to 8 inch depth is the second. Adjacent foundation settlement is the third, especially where a walk runs along the front of a mill house and the porch stoop has dropped as the house corner has moved. I look at all three on the inspection and I tell you which one is driving the specific slab we are looking at, because the fix depends on it.
The Catawba River proximity story shows up in concrete lifting through a specific pathway — chronic soil moisture on the flatter blocks east of Central Ave and along Wilkinson Blvd keeps the subgrade soft, and that means poly injection has to be sequenced carefully because you do not want to inject foam into wet soil that will migrate the material sideways instead of lifting the slab. I check moisture with a soil probe before drilling any ports, and if the subgrade is genuinely saturated we address the drainage first — regrading, downspout extensions, sometimes a French drain along the affected edge — and let it dry out for a couple of weeks before we come back to lift.
Gaston County does not require a permit for slab lifting itself — poly injection is not a permitted trade any more than it is in Mecklenburg. Where a permit shows up is if the scope includes any structural work adjacent to the lift, like footing repair on a stoop that has settled because the footing itself moved. That pulls a building permit through Gaston County Building Inspections. For a straight approach or walkway lift on stable subgrade, no permit is needed. If the slab we are lifting is on a Belmont Abbey-adjacent address or one of the historic-designated properties along Main St, we check any easement or historic considerations before we drill — mostly a non-issue on residential walkways and driveways, but occasionally a factor on a specific site.
Turnaround is typically same-day for a straightforward driveway or walkway lift. On the McLean fill-dirt job I opened with we were on-site three and a half hours from arrival to cleanup. Bigger jobs with multiple slabs or where we need to stage lifts across multiple visits run one to two working days. Cure and full drivability is two hours after the last injection, which is the poly foam's biggest advantage over old-school mudjacking — you can be back on the driveway the same afternoon instead of waiting overnight for slurry to set.
Primary material is HMI TerraThane 24024 two-component polyurethane, the workhorse for most Belmont exterior slab jobs — driveways, approaches, walkways, garage floor edges, porch stoops. Density is around 4 pounds per cubic foot after full expansion, compressive strength runs 40 to 60 psi at 24 hours which is well above what any residential slab is asking of it. Injection ports are 5/8-inch drilled through the slab at 18-inch spacing along the settled edge, staged in three separate lift passes so we can control final elevation to within a quarter inch instead of over-injecting on a single shot and having to trim material off the top.
For interior partial-slab work — which comes up occasionally on Belmont houses that have a slab-on-grade addition attached to an original crawlspace footprint, or on some of the newer builds in McLean that have finished basement-slab-and-crawlspace hybrids — we use the same TerraThane 24024 or step down to HMI TerraThane 15012 for smaller void-fill applications where lift precision matters more than raw strength. Injection ports on interior slabs are patched with color-matched grout or mortar rather than the exterior-grade patching we use outdoors.
The lift itself uses a pneumatic delivery system pushing metered A-side and B-side components into the port simultaneously. Reaction happens inside the substrate, foam expands under the slab and hydraulically lifts against the concrete above. We monitor elevation with a laser level running from a reference point on the adjacent stable slab or foundation, and we stop each injection pass at the target elevation rather than trying to hit final grade on the first shot. Cleanup is standard — cured foam trimmed flush with the port, port patched, work area swept and reviewed with the homeowner before we roll.
Yes — Belmont is a regular concrete lifting route. Free on-site inspection anywhere in Belmont, fixed written quote before we touch anything.
Belmont concrete lifting splits between two very specific job types — 2000s subdivision fill-dirt settlement in McLean and Reflection Pointe off S Point Rd, and century-old sidewalk-and-stoop settlement in the mill village downtown — and neither one behaves like a typical Charlotte suburban slab settlement, which is usually driven by drainage rather than fill or tree roots.

Classic fill-dirt settlement pattern. When the developer built the neighborhood in the mid-2000s they brought in fill to level the lots — that's normal for hillside subdivisions like McLean and Reflection Pointe off S Point Rd. The garage slab sat on original grade because it was poured on undisturbed soil where the foundation footprint was excavated, but the driveway approach sits on top of the fill that was placed around the foundation. Fill compacts over time. Undisturbed original grade does not. So you get differential settlement right at the transition — the approach drops an inch or two while the garage slab stays put. Poly foam injection is the right fix because it stabilizes the fill matrix at the same time it lifts the slab, so you do not get the same settlement again in another decade.
Depends on the slab condition. If the concrete itself is sound — no through-cracks that break the slab into multiple pieces, no severe spalling on the surface — then yes, we can lift a 1920s or 1930s Belmont sidewalk with poly foam and get it back to level. On mill village front walks along Main St, Woodlawn Ave, or Central Ave I have lifted plenty of original concrete that was poured when the mills were running. Where lifting is not the right call is when the slab has broken into three or four separate pieces because a mature oak root pushed it apart, or when the surface has spalled so badly that the concrete is losing material at the injection port. Those get demo and repour instead. I tell you which one applies on the inspection.
Yes, and this is a common mill house Belmont job. Century-old porch stoops on brick pier houses in the historic core have settled toward the foundation over the decades because the soil right against the house was disturbed during original construction and never fully re-consolidated, while the outer edge of the stoop sits on more stable grade further out. That gives you the classic tilt back toward the house. Poly injection at the settled edge — the side closest to the foundation — brings the stoop back to level or even to a slight positive slope away from the house so water sheds off instead of pooling against the sill. On some very small stoops where the total slab area is under 12 square feet, demo and repour is honestly the smarter scope than lifting, and I will tell you that if it applies.
Not directly. The injection is done through the slab from above, the foam expands under the concrete only, and there is no excavation and no material disruption to the surrounding soil beyond the immediate lift zone. Plantings immediately adjacent to a walkway or stoop we are lifting stay in the ground. On older Belmont properties where mature landscape lines the front walk — boxwoods, azaleas, hollies typical of the historic core — the roots that are actually pressing against the underside of the slab and causing settlement do get displaced when the foam expands, but the plant itself is not being cut or dug up. If a specific plant has grown in such a way that its trunk is against the slab edge, we work around it and place ports to avoid the immediate root zone.
