How foam lifting works
- The crew drills small 5/8-inch holes in the sunken slab. That is about the size of a penny.
- They inject expanding polyurethane foam under the slab. The foam fills the empty space and lifts the slab back toward level.
- The foam weighs only 2 to 4 pounds per cubic foot, so it adds very little weight to clay soil.
- The holes are patched. The foam cures in 15 minutes, and you can walk or drive on it.
Pool and irrigation lines matter here. Holes go where the foam can reach the empty space without hitting a pipe. If a line is leaking, it should be fixed first so the soil stops washing out.
When does a lip become a trip hazard?
Move the slider to match the height of the lip between two slabs. Measure from the top of the low slab to the top of the high slab.
Trip hazard
This is general guidance, not a legal ruling. Rules and deadlines vary by HOA. Check your community documents or ask your HOA management company.
Drawing exaggerates height so small lips are easy to see.
2026 comparison: foam vs mudjacking vs replacement
Weight matters on Southeast Valley clay. Heavy slurry adds load to soil that has already settled once. Light foam adds very little.

Why concrete sinks in Queen Creek and San Tan Valley
Most slabs here sink because the soil under them moves. The house stays put, so you see a lip or gap where the two meet. Four local causes come up again and again.
Loose builder backfill
Builders often fill around post-tension foundations with soil that was never packed down. Over time it settles, and the driveway or patio on top of it drops.
Clay that shrinks in summer heat
Expansive clay swells when wet and shrinks when it dries out. Long hot summers pull moisture out and leave gaps under slabs.
Monsoon runoff
Heavy monsoon rain runs along slab edges and washes soil out from underneath. The slab loses support and starts to tip or sink.
Leaking PVC lines
Leaking Schedule-40 PVC irrigation or pool lines soften and wash out the soil below. Fix the leak before a lift so the slab stays up.
Service areas
The same 2026 rates apply everywhere we cover: $6 to $12 per sq ft with a $650 minimum.

Frequently asked questions
How much does concrete leveling cost in Queen Creek in 2026?
Foam concrete leveling, also called polyjacking, costs $6 to $12 per square foot in Queen Creek and San Tan Valley in 2026. Every job has a $650 minimum charge. Tearing out and replacing the same slab usually costs $18 to $28 or more per square foot.
Why is there a $650 minimum charge?
The crew, truck, and foam rig come out for every job, no matter how small. So every job has a $650 minimum charge. If you have more than one sunken area, fixing them in the same visit spreads that minimum across more work and usually saves money.
How soon can I walk or drive on the slab?
The foam cures in about 15 minutes. After that you can walk or drive on the slab. Most sidewalk jobs take about 1 hour on site. Driveway aprons and patios take about 2 hours, and pool decks take 2 to 3 hours.
Will foam lifting damage my pool or irrigation lines?
A careful crew finds pool and irrigation lines before drilling and places the small 5/8-inch holes away from them. The foam fills the empty space under the slab and does not need to touch the pipes. If a PVC line is leaking, fix it before the lift.
Is polyjacking better than mudjacking on clay soil?
For most slabs here, yes. Foam weighs 2 to 4 pounds per cubic foot and goes in through a 5/8-inch hole. Mudjacking slurry weighs 100 or more pounds per cubic foot and needs a 2-inch hole. Heavy slurry adds load to clay soil that already settled.
Can a sunken driveway apron at the garage door be lifted?
Yes. The apron often sits on loose builder backfill next to a post-tension foundation. When that soil settles, the apron drops and leaves a lip at the garage. A 2-car or 3-car apron of 120 to 240 square feet typically costs $950 to $1,850.
What should I do if my HOA sent a trip hazard letter?
Note the deadline, take photos, and measure the area in square feet. Then get a written estimate and ask your HOA whether a scheduled repair date meets the deadline. Sidewalk jobs of 50 to 100 square feet typically cost $650 to $950. Rules vary by HOA.
