What concrete leveling costs in Lexington
Planning ranges compiled from published sources, what pushes a quote up or down, and the questions that make two bids actually comparable. These are budgeting figures for Lexington, not a quote for your property.
Budgeting
Typical ranges
Mudjacking runs about $3 to $6 per square foot; polyurethane foam $5 to $25, and can reach roughly four times mudjacking at the top of the range. Foam is lighter, cures in minutes, and uses smaller holes; mudjacking is cheaper and uses heavier material. Small single-slab jobs usually carry a minimum charge that dominates the per-foot figure.
| Scope | Typical range | Most common |
|---|---|---|
| Mudjacking, straightforward slab | $3 – $6 | $4 |
| Polyurethane foam, straightforward slab | $5 – $15 | $9 |
| Foam, deep settlement or large void | $10 – $25 | $16 |
Variables
What moves the price
Two quotes on the same property can differ by a wide margin and both be honest. These are usually why.
Method chosen
The dominant variable. Foam costs substantially more per square foot but is lighter, sets in minutes, uses smaller ports and does not add significant weight to already weak soil.
Void volume
How far the slab has dropped and how much empty space is underneath determines material consumed. A slab that has sunk two inches over a large area is a very different quantity from a corner that has dipped.
Slab type and thickness
A reinforced garage floor or driveway behaves differently from a thin patio or walkway. Thicker slabs resist cracking during lift but need more injection points.
Minimum charges
Mobilising equipment for a single sunken step or one panel means the job is priced near a minimum rather than by area. Combining several areas into one visit is markedly better value.
Cause of settlement
If a leaking pipe or an eroding downspout line is the cause, fixing it is a separate cost and a necessary one. Lifting over an unresolved cause buys a season or two.
Access
Equipment needs to reach the slab. Rear patios behind narrow gates, interior floors, and slabs in confined spaces all add handling time and sometimes different equipment.
Comparing quotes
Questions worth asking anyone who bids
Ask every bidder the same list. The differences in the answers are the real difference between the numbers.
- Why do you think this slab settled, and what happens if that cause is not addressed?
- Foam or mudjacking for my situation, and what is the reasoning?
- How large are the injection holes and how visible will the patches be?
- Is joint and crack sealing included, or quoted separately?
- How long before I can drive on or use the slab?
- What is the warranty, and does it cover re-settlement or only workmanship?
- At what point would you tell me to replace this slab instead of lifting it?
Pitfalls
Where people lose money
Lifting without fixing the water
By far the most common failure. If a downspout is discharging alongside the slab or a drain is broken, the soil washes out again and the slab settles again, usually within a couple of seasons.
Lifting a slab that has structurally failed
A slab broken into several rocking pieces cannot be restored by lifting. Injecting under it produces a temporarily level surface made of independent fragments that will move apart again.
Choosing on price alone between methods
Mudjacking is cheaper but adds real weight to soil that has already proven unable to support load. On weak or saturated soils that can accelerate the next settlement, which is exactly the case foam exists to address.
Skipping joint sealing
Open joints let surface water run straight back under the slab. Sealing is a small line item that protects the whole repair, and leaving it out is a false economy.

What this site is
Lexington Concrete Lifting is a referral site, not a contractor. We do not hold a license, own a truck, or send a crew. We research concrete leveling pricing and practice, publish what we find, and hand your request to a vetted local company in Lexington.
That company quotes, schedules, and stands behind its own work, and it contracts with you directly. We do not mark up the price, and you pay us nothing.
More questions
How much does concrete leveling cost?
Mudjacking runs roughly $3 to $6 per square foot and polyurethane foam roughly $5 to $25, with foam reaching about four times mudjacking at the top of its range. Small jobs are usually priced against a minimum charge rather than by area, so a single sunken step can cost more per foot than a whole driveway. Combining areas into one visit is the main way to improve value.
Is polyurethane foam better than mudjacking?
It is better in specific ways rather than universally. Foam is far lighter, so it does not add load to soil that has already failed; it cures in minutes so you can use the surface almost immediately; and its injection ports are much smaller. Mudjacking costs considerably less and is perfectly appropriate on stable soils and utility slabs where hole size does not matter.
How long does concrete leveling last?
If the underlying cause was addressed, a properly executed lift can last many years, effectively as long as the slab itself. If the cause was not addressed, expect it to settle again, sometimes within a single wet season. The durability question is almost entirely about drainage and soil rather than about which injection product was used.
Can any sunken concrete be lifted?
No. Lifting works on slabs that are still structurally sound, even if cracked in one or two places. A slab that has broken into multiple pieces that move independently, or one that is severely spalled and deteriorated, is a replacement candidate. A contractor willing to lift anything regardless of condition is worth a second opinion.
How long does the work take?
Most residential jobs are completed in a few hours to a day. With polyurethane foam the material cures within minutes, so a driveway can often take traffic the same day. Mudjacking uses a heavier slurry that needs longer before full load, commonly a day or so. Both are dramatically faster than removal and replacement, which involves cure time measured in days to weeks.
Will the holes be visible afterwards?
Yes, on close inspection. Foam ports are around five-eighths of an inch and mudjacking holes one to two inches; both are patched, and both remain discernible on a weathered slab because the patch material will not match aged concrete exactly. On a utility surface this is irrelevant; on a decorative or stamped surface it is worth discussing before you commit.
Is leveling cheaper than replacing the concrete?
Substantially, usually by a wide margin, and it is also much faster and less disruptive. Replacement means demolition, disposal, forming, pouring and cure time, plus a new slab that will not match the color and finish of the surrounding concrete. Replacement becomes the right answer when the slab itself has failed rather than merely settled.
What causes concrete to settle in the first place?
Almost always movement in the soil underneath rather than a defect in the concrete. Common causes are water washing out fines along a downspout or drainage path, backfill that was never properly compacted when the structure was built, erosion, drought-related soil shrinkage, and leaking supply or drain pipes. Identifying which one applies is the difference between a repair and a recurring expense.
