Concrete Leveling
Concrete Leveling and Polyjacking in Columbia, SC
Have uneven or settled concrete?
Concrete Leveling Without Replacing the Slab
A sunken slab is more than an eyesore. It can cause trips and falls, let water run toward the house, and crack more over time. Often the slab itself is fine. The soil under it is the problem.
Foundation Pros of Columbia lifts settled slabs and fills the voids beneath them. If a slab is tied to a larger foundation issue, see foundation repair and piering in Columbia, SC.
Signs a slab needs lifting
- Sunken sections of a driveway or walkway
- Trip hazards at slab joints
- Gaps between a slab and the garage door
- Water pooling on a patio or slab
- A slab that tilts toward the house
- A hollow sound when you tap the concrete
Polyjacking, Mudjacking, or Replacement?
All three fix a sunken slab. They differ in weight, hole size, and disruption.
| Feature | Polyurethane foam | Mudjacking | Replacement |
|---|---|---|---|
| How it works | Expanding foam fills voids and lifts | Cement slurry is pumped under the slab | The slab is broken out and re-poured |
| Hole size | Small | Larger | Not applicable |
| Weight added | Light | Heavy | New slab |
| Disruption | Low | Moderate | High |
The right choice depends on the slab, the soil, and the cause. We explain which fits before work starts.
Our 5-Step Concrete Leveling Process
Every job follows the same path. The details change with your home.
- AssessmentWe check the slab and find the voids. We look for the water source behind the settling.
- DrillingWe drill small holes at planned points across the slab.
- InjectionWe inject foam and watch the slab rise. We stop when it is level.
- SealingWe fill the holes and clean the surface.
- Final QAWe check level and drainage and review the work with you.
What Affects the Cost of Concrete Leveling?
We do not quote prices without seeing the slab. These factors move the price the most.
- Slab size: More area means more holes and more foam.
- Drop depth: A larger drop needs more material.
- Void depth: Deep voids take more foam to fill.
- Cause: Water sources may need a fix. See basement waterproofing and drainage in Columbia, SC.

Why Concrete Sinks in Columbia
Sandy soils on the south and east side drain fast. When rain runs across a slab or a downspout dumps at its edge, the water can carry fine sand out from under it. That leaves a void, and the slab drops.
On the clay side, wet soil can soften. New neighborhoods may have fill that was not packed well. Heavy summer storms then test every weak spot.
We do concrete leveling in Columbia and nearby towns, including Lexington, Irmo, West Columbia, Cayce, Forest Acres, Blythewood, and Chapin. See our concrete leveling and foundation service areas near Columbia, SC.
Concrete Leveling Questions in Columbia, SC
What is polyjacking?
Polyjacking lifts a sunken concrete slab. We drill small holes and inject expanding polyurethane foam under it. The foam fills voids and raises the slab to the right level.
How long before I can use the driveway?
Foam cures quickly. We tell you when the slab is ready. Many jobs are done in a single visit.
Will the slab sink again?
It can if water keeps washing soil out from under it. We look for the cause. Fixing gutters, downspouts, and grading helps the lift last.
How much does concrete leveling cost in Columbia?
Other cost guides report about $630 to $1,900 for a typical job, or $5 to $25 per square foot for foam. Your price depends on slab size, drop, void depth, and access. We give you a free estimate and a written scope after a site visit.
Why do slabs sink in Columbia?
Sandy soil can wash out under a slab when water runs across it. Wet clay can soften. Fill under new construction can settle. Heavy summer storms speed this up.
What is concrete leveling?
Concrete leveling raises a sunken slab to the right height. We do it with polyjacking, which injects expanding polyurethane foam under the slab. Mudjacking does the same job with cement slurry.
Is concrete leveling better than replacing a slab?
Often it is less disruptive, because the slab stays in place. A slab that is badly broken may still need replacement. We tell you which one fits.
