Knoxville's Trusted Concrete Lifting Company
Raise sunken driveways, sidewalks, patios, and pool decks in hours — not days. Polyurethane foam injection and mudjacking from a locally owned East Tennessee crew.
Concrete Leveling Done Right
Sunken concrete is a problem. We're the fix.
East Tennessee's red clay, karst limestone, and freeze-thaw cycles drop tens of thousands of slabs every year. Replacing them costs four times more, takes a week, and doesn't fix the soil that caused the failure in the first place.
Knoxville Concrete Lifting raises your concrete back to grade with high-density polyurethane foam — engineered for our soils, ready for traffic in 15 minutes, and backed by a lifetime materials warranty.

What We Do
Concrete Lifting Services Across East Tennessee
Polyurethane Concrete Lifting
Polyurethane concrete lifting — often called polyjacking or foam jacking — is the modern, engineered solution for raising sunken concrete around your Knoxville home or business. By injecting a high-density, closed-cell polymer foam through dime-sized holes, we restore your slabs to a safe, level position in a matter of hours, not days.
Learn moreMudjacking
Mudjacking — also called slabjacking, slab jacking, or concrete raising — is the traditional method of lifting sunken concrete by pumping a cement-and-aggregate slurry beneath the slab. For decades, mudjacking has been the go-to fix for Knoxville driveways, sidewalks, and patios that have settled into the soft red clay common across East Tennessee.
Learn moreDriveway Leveling
A sunken driveway isn't just unsightly — it sends water toward your foundation, damages your vehicle, and quietly drops your home's value. Knoxville Concrete Lifting levels residential and commercial concrete driveways across Knox, Blount, and Sevier Counties using high-density polyurethane foam.
Learn moreSidewalk Leveling
Uneven sidewalks are the #1 cause of slip-and-fall liability claims for Knoxville homeowners, HOAs, and small businesses. We level concrete sidewalks with polyurethane foam, eliminating trip hazards and restoring ADA-compliant surfaces — usually in under an hour per panel.
Learn morePatio Leveling
A sunken patio sends rainwater toward your home's foundation, ruins outdoor furniture leveling, and turns weekend cookouts into wobbling-table frustration. Knoxville Concrete Lifting raises pitched, settled, and gapped patios across Knox, Blount, and Sevier Counties — without tearing out your hardscape.
Learn morePool Deck Leveling
A sunken pool deck is more than ugly — it's a safety hazard for bare feet and a structural risk for the pool itself. Knoxville Concrete Lifting raises concrete pool decks using polyurethane foam that's waterproof, chemically resistant to chlorine, and ready for swim use the same day.
Learn moreGarage Floor Leveling
When a garage floor sinks, rainwater stops draining out and starts seeping in — under the apron, under your stored boxes, and into your drywall. We level garage floors across the Knoxville area with polyurethane foam, restoring proper pitch and protecting everything you keep inside.
Learn moreConcrete Crack Repair
Cracks in concrete are more than cosmetic — they're entry points for water, road salt, and soil erosion that accelerate slab failure. Knoxville Concrete Lifting seals and stabilizes cracks in driveways, sidewalks, patios, and foundations using polyurethane and epoxy injection systems.
Learn moreVoid Filling & Soil Stabilization
When soil washes out from beneath a slab or foundation, the void it leaves behind is a ticking clock. Knoxville Concrete Lifting fills subsurface voids and stabilizes weak soils with structural polyurethane foam — a permanent solution that compacts loose soil and provides long-term load support.
Learn moreCommercial Concrete Lifting
Downtime is expensive. Knoxville Concrete Lifting performs commercial polyurethane lifting and mudjacking on warehouse floors, loading docks, parking lots, retail walkways, school sidewalks, church properties, and municipal infrastructure across Knox, Blount, and Sevier Counties — with after-hours and weekend availability so your operation never stops.

FAQ
Frequently Asked Questions
What is polyurethane concrete lifting?+
Polyurethane concrete lifting (also called polyjacking) is a modern method of raising sunken concrete by injecting a high-density, closed-cell polymer foam through dime-sized holes. The foam expands beneath the slab, fills voids, and lifts the concrete back to grade in under an hour.
How much does concrete lifting cost in Knoxville?+
Most residential lifts in the Knoxville area run $850–$2,400. Single-panel sidewalk repairs start around $300. We provide flat-rate written quotes with no surprise charges.
How long does it take?+
Most residential jobs are completed in 1–4 hours, and the lifted concrete is ready for foot traffic immediately and full vehicle loads within 15 minutes.
What areas do you serve?+
Every Knoxville neighborhood plus all of Blount County (Maryville, Alcoa, Townsend, Walland) and Sevier County (Sevierville, Pigeon Forge, Gatlinburg, Seymour, Kodak).
Is polyjacking better than mudjacking?+
Polyjacking is lighter, faster-curing, and uses smaller holes — making it the better choice in East Tennessee's unstable clay and karst soils. We also offer traditional mudjacking when it's the right fit.
Do you offer a warranty?+
Yes — our polyurethane lifts carry a written lifetime materials warranty against re-settlement of the lifted slab.
