The proven, budget-friendly way to lift sunken concrete — cement slurry pumped under the slab, raising driveways, sidewalks, and patios back to level in hours.
Small holes (about 1–2 inches) are drilled through the sunken slab in a grid pattern.
A cement-based slurry — water, soil, and cement — is pumped under the slab, filling voids and hydraulically lifting the concrete.
The crew levels the slab as it rises, then patches the drill holes. You keep your existing concrete — no color mismatch.
The slurry sets up in about 24 hours. Foot traffic sooner; vehicles the next day.
| Project | Typical range |
|---|---|
| Sidewalk section (~120 sq ft) | $350–$700 |
| Patio / porch (~200 sq ft) | $500–$1,000 |
| Driveway section (~220 sq ft) | $650–$1,300 |
| Full driveway (~500 sq ft) | $1,500–$2,900 |
Around $3–$8 per square foot. A sidewalk section runs $350–$700; a full driveway $1,500–$2,900. See the full cost guide.
Typically 5–10 years. The slurry is heavy and can settle over time, especially if the underlying drainage issue isn't fixed. It's still far cheaper than replacement even if redone once.
Most residential jobs take a few hours. The slurry needs about 24 hours to cure before heavy use — plan to keep cars off the driveway overnight.
Holes are typically 1–2 inches wide and get patched with concrete. You'll see them if you look closely, especially on decorative concrete — one reason foam (with smaller holes) is popular for visible areas.
It can lift a cracked slab, but it can't un-crack it. If the concrete is crumbling or shattered, replacement is the honest answer — a good contractor will tell you which one you're looking at.
