Best Concrete Lifting Contractors Burlington NC

Whether lifting makes sense depends almost entirely on what era of concrete you own. Reinforced slabs — most of Burlington's newer flatwork — lift beautifully: the steel holds the panel as one plate, so raising it under controlled pressure returns the whole surface to plane. The unreinforced concrete common to the city's mill-era neighborhoods is a different patient; once it has broken into independent pieces, lifting moves the pieces around rather than restoring a surface, and we will say so at the estimate rather than after. Candid triage is the value here: lift what lifting can genuinely save, and put replacement money only where replacement is truly the answer.

In Burlington specifically, lifting work runs through neighborhoods like Glencoe Mill Village, Mackintosh on the Lake, Downtown Burlington. Burlington's mill-town heritage is the single biggest driver of concrete work here. That local ground truth — not a generic spec sheet — is what the crew builds against when they form up a Burlington repair call.

Our Lifting & Leveling Services

Slab lifting covers a range of surfaces and settlement patterns, and the right method depends on how much lift is needed, what's under the slab, and how sensitive the surrounding work is to the injection process.

• Driveway apron lift — raising the section of drive that meets the road, a very common failure spot as the apron base loses support
• Full driveway panel lift — bringing a settled panel back to grade with the surrounding panels
• Sidewalk panel lift — fixing trip hazards where a panel has heaved from tree roots or settled after utility work
• Patio slab lift — leveling a settled patio, often at the corner farthest from the house where fill soil compacted over time
• Garage floor lift — raising a garage slab that's separated from the foundation, dropped at the door, or settled toward one wall
• Pool deck lift — restoring level around a pool where the deck has sunk unevenly, protecting the coping and the pool structure
• Porch and stoop lift — raising a settled porch slab back to its original elevation
• Step and stair leveling — correcting settlement in poured concrete step assemblies
• Void filling under slabs — stabilizing a slab that hasn't dropped yet but has voids underneath that will let it drop
• Mud-jacking (cementitious slurry) — the traditional method, heavier material, appropriate for larger open lifts
• Polyurethane foam — modern method, lighter material, faster cure, minimal disruption

Most residential lifts in NC land on either a driveway apron, a sidewalk panel, or a settled corner of a patio or garage floor.

How Lifting Actually Works

Both mud-jacking and polyurethane foam work on the same principle: fill the void that let the slab settle, then use continued injection pressure to lift the slab back to grade. What differs is the material, the hole size, and the cure behavior.

Mud-jacking (cementitious slurry):

• Holes drilled through the slab at roughly 1 to 1.5 inches diameter, typically on a three-to-five-foot grid
• Material pumped through the holes — a slurry of Portland cement, sand, and sometimes fly ash
• Slurry spreads through the void under the slab, fills it, and starts lifting the slab as injection pressure builds
• Cures overnight; slab typically takes traffic within 24 to 48 hours
• Heavier per cubic foot than foam — adds weight the base underneath has to carry
• Older method, well-proven, appropriate for larger fills and driveway apron work

Polyurethane foam (structural expanding foam):

• Holes drilled at roughly 3/8 to 5/8 inch diameter — much smaller and less visible after patching
• Two-part polyurethane injected through the holes as a liquid; it expands and cures into a closed-cell structural foam within minutes
• Lift is controlled by the operator watching the slab elevation in real time
• Cures fast; slab typically takes foot traffic within 15 minutes and vehicle traffic within a few hours
• Very light per cubic foot compared to slurry — adds almost no weight to the base underneath
• Modern method, particularly good for sensitive lifts (near foundations, around pool coping, on floating slabs)

Both methods leave the slab in place. The concrete you have stays; the void underneath gets filled and the slab returns to grade. Cost differs — polyurethane is typically a higher cost per lift but comes back into service faster and disrupts the site less.
