Concrete Leveling & Slab Lifting in Winston-Salem, NC
Levelling lifts a sunken slab back into position instead of tearing it out, and where the concrete itself is still sound it costs well under a full replacement of the same section. It is also faster by a wide margin: most jobs are done in a day, and you can drive or walk on the slab within about an hour of the last injection instead of waiting a week for new concrete to cure.
It only works when the concrete itself is still sound. If a slab has settled as one piece because the fill underneath washed out, lifting it is the cheaper and faster answer. If it has cracked into several pieces that move independently, there is nothing solid left to lift and replacement is the honest recommendation.
What Moves the Price of Concrete Leveling & Lifting in Winston-Salem, NC
What changes
Effect on your price
Number and size of sunken sections
Levelling is priced by the area being lifted, so one settled walkway panel and a whole sunken garage floor are very different jobs.
How far it has to lift
The void under the slab is what gets filled. A deeper void takes more material, and the material is most of the cost.
Method
Polyurethane foam injection and traditional mudjacking price differently. Foam is lighter, cures in minutes and uses smaller holes; mudjacking uses cheaper material in larger volume.
Why it settled
Washed-out fill, a leaking downspout or a broken drain line all have to be dealt with or the slab will sink again. That correction is priced on top.
Whether the slab is still sound
Levelling only makes sense on concrete that is intact. A slab that is badly broken up gets replaced instead, and we will tell you which one you have.
Access to drill and inject
Interior slabs, tight crawl spaces and finished areas take longer to set up and protect.
Every job is priced on site. We measure, check the base and the grade, and put a written price in your hand before any concrete is ordered.

Common Questions
Is concrete leveling cheaper than replacement?⌄
Usually much cheaper. Lifting a sunken section commonly costs a fraction of removing and repouring it, and it can often be done in a single visit with the surface usable the same day.
How long does a lifted slab stay level?⌄
It depends on why it sank. If the void was a one-off from a washout or poor backfill, the repair is durable. If water is still actively moving soil underneath, the drainage has to be fixed too or it will settle again.
When is leveling not the right answer?⌄
When the slab has broken into multiple pieces that move independently, when it is badly spalled or crumbling, or when the base has failed across a wide area. In those cases replacement lasts longer.
