Phoenix driveways sink. Between expansive clay soils, irrigation water tracking under the slab, poor compaction during the housing boom, and 100°+ summers that dry the soil into shrinkable blocks — settlement is more the rule than the exception in the Valley.
What we see most
- The garage-to-driveway transition has dropped — water now pools at the door
- The driveway sloped toward the house instead of away from it
- Sections near the street settled where the soil was disturbed for utilities
- One side dropped lower than the other — usually where irrigation runs along the foundation
- The driveway is splitting along a control joint with one side dropping
How driveway leveling works
We use polyurethane foam injection — the same lift technology departments of transportation use on highway slabs. The process is straightforward:
- We drill — penny-sized injection holes (≈5/8") through the slab at strategic points
- We inject — a specialized gun pumps high-density polyurethane foam through the holes
- It expands — the foam expands ~20× its liquid volume, fills voids, compacts loose soil, and lifts the slab
- We measure — laser-level monitoring stops the lift exactly at grade
- We patch — holes patched flush, ready for foot traffic in 15–30 minutes
- You drive on it — same day, full load. No 7–28 day cure
Why foam beats mudjacking and replacement
Mudjacking pumps a heavy slurry of cement and dirt under the slab — it works, but the holes are two inches across, the cure is 24–48 hours, and the slurry can erode or shrink over time. Tear-out and replacement is exactly what it sounds like: jackhammers, debris, days of curing, damaged landscaping, and a brand-new slab that may settle the same way the old one did because nothing was done about the soil underneath.

Driveway leveling cost in Phoenix
Most driveway lifts run $1,200 to $3,500 depending on:
- Square footage of the affected area
- How much settlement needs to be corrected (¼" vs. 2"+)
- Whether voids need to be filled before the lift
- Whether crack repair is needed afterward
Replacement of a typical two-car driveway in Phoenix runs $8,000 to $15,000 — and adds days of cure time before you can use it. Foam injection generally saves 70–80% and is done the same day.
What about the crack?
Lifting the slab does not close existing cracks — but it stops them from getting worse, and lets us do crack repair on a stable surface. Read more about crack repair →
