Diagnose Your Concrete Issue
What's Wrong With Your Concrete?
Most homeowners don't search for "concrete lifting" — they search for the problem. Find your symptom below, learn what's causing it, and see how Knoxville Concrete Lifting fixes it in hours.
Sinking Driveway
Driveway dropped at the garage apron or street? Water pooling where it shouldn't? Learn why Knoxville driveways sink and how to fix them without replacement.
Uneven Sidewalk & Trip Hazards
Sidewalk slabs lifted by tree roots or dropped by clay settlement create dangerous lips. Here's how to make sidewalks safe and ADA-compliant again.
Sunken Patio or Pool Deck
A pitched patio sends water toward your foundation. A dropped pool deck creates a stub-toe hazard. Both can be leveled in hours with polyurethane foam.
Garage Floor Settling
Garage floors that slope toward the house let rainwater inside. Polyurethane lifting re-levels the slab and stops the leak at the source.
Why Concrete Sinks
Understand the soil, drainage, and weather conditions that cause concrete to settle across Knoxville and East Tennessee — and what actually fixes it.
Leveling vs Replacement
Compare cost, downtime, and long-term results of lifting your existing concrete versus tearing it out and pouring new.
Not Sure What to Call Your Problem?
That's normal. Most people don't know terms like "polyjacking" or "slab leveling" until they start researching. What they know is that their driveway has a low spot, their sidewalk has a lip, or their patio tilts toward the house. Those symptoms all point to the same underlying issue: the soil under your concrete has failed, and the slab has followed it down.
East Tennessee makes this especially common. Our red clay expands when wet and shrinks when dry. Our karst limestone hides voids. Our freeze-thaw cycles stress slabs every winter. And decades of poor compaction in subdivisions from Farragut to Sevierville have left thousands of driveways and patios sitting on soil that was never ready to hold them.
The good news is that most settled concrete can be lifted — not torn out. Polyurethane concrete lifting fills the voids, densifies the soil, and raises the slab back to a safe, level position. The work takes hours, not days, and you can walk on it immediately.

FAQ
Concrete Problem FAQ
Why is my concrete sinking?+
Concrete sinks when the soil beneath it compresses, washes out, or develops voids. In East Tennessee, the main culprits are expansive red clay, karst limestone, poor original compaction, heavy rain, and freeze-thaw cycles.
Can sunken concrete be lifted without replacing it?+
Yes. Polyurethane concrete lifting injects high-density foam beneath the slab through small holes, raising it back to grade without tear-out, new concrete, or long cure times.
How do I know if my concrete problem needs lifting or replacement?+
If the slab is structurally sound — no severe crumbling or widespread cracking — lifting is usually the better choice. It costs less, finishes in hours, and addresses the soil problem that caused the settlement.
What does concrete lifting cost in Knoxville?+
Knoxville Concrete Lifting has a $1,500 minimum for all jobs. Most residential lifts fall between $1,500 and $2,400, though larger driveways, pool decks, and multi-slab projects can run higher. We provide flat-rate written quotes.
