Concrete leveling vs. replacement
I'm Devon. A sunken driveway, sidewalk, or patio slab gives you two options: lift it back into place, or tear it out and pour new. Leveling costs 50–70% less — but it's not always the right call. Here's the honest breakdown.
2026 cost comparison
| Repair / service | Cost range | Unit | When it applies |
|---|---|---|---|
| Mudjacking / slabjacking | $500–$1,500 | Per section | Sunken slabs, 1–4 inches of lift |
| Polyurethane foam leveling | $1,000–$3,000 | Per project | Lighter, longer-lasting lift |
| Concrete crack repair | $250–$800 | Per repair | Non-structural cracks in slabs |
| Tear-out and replacement | $3,000–$8,000+ | Per project | Failed slabs (get a local quote) |
Leveling ranges from the Woogoro 2026 cost guide. Replacement varies widely by area, thickness, and access — always get a local quote for the comparison.
How leveling works
Mudjacking pumps a cement-based slurry under the slab through small holes, lifting it back to grade. Proven, affordable, heavier material. Polyurethane foam injects expanding foam — lighter, cures in minutes instead of days, less invasive, but pricier. Both beat replacement on cost and downtime when the slab itself is sound.
When leveling wins
- The slab is structurally sound — just settled unevenly
- Settlement is 1–4 inches (deeper can still work; ask)
- The soil cause is stable — not actively washing out
- You want it done in hours, not days — foam cures fast, mudjacking in a day or two
When replacement wins
- The concrete is crumbling, spalling, or extensively cracked — leveling can't fix disintegrating concrete
- Drainage pitches toward your foundation — this is a regrade/repour job, and it matters more than the slab
- Soil is actively eroding underneath — lifted slabs will just sink again
- The slab has no reinforcement and heavy vehicle loads — a proper repour with rebar outlasts any lift
Mudjacking vs. poly foam: the real trade-offs
- Cost: mudjacking is cheaper, often by half.
- Weight: foam is dramatically lighter — matters on soft or questionable soil.
- Cure time: foam in minutes; mudjacking needs a day or two before heavy loads.
- Longevity: foam generally lasts longer and resists washout better.
- For driveways: ask which the contractor warranties under vehicle loads — that's the answer that matters, not the brochure.
The trip-hazard math
A sidewalk lip over 3/4 inch is a trip hazard and, in many places, a liability issue. Leveling a settled sidewalk section ($500–$1,500) vs. replacing it — and vs. the cost of someone getting hurt — is one of the clearest wins in this whole category.

Frequently asked questions
How much does it cost to level a concrete driveway in Indianapolis?
Mudjacking runs $500–$1,500 per section; polyurethane foam runs $1,000–$3,000 per project. Both are typically 50–70% cheaper than tearing out and replacing.
How long does concrete leveling last?
If the underlying soil is stable, many years — often a decade or more. If soil keeps settling or washing out, any leveling is temporary. A good contractor tells you which situation you're in before quoting.
Can all sunken concrete be leveled?
No. Sound slabs that have settled: yes. Crumbling, spalling, or extensively cracked slabs: no — those need replacement. Drainage problems need regrading regardless.
Will leveling fix water pooling toward my foundation?
It can restore proper pitch if settlement caused the problem. But if the original grade was wrong, you need regrading or replacement — lifting a badly graded slab just gives you a level slab that still drains the wrong way.
