Mudjacking in Sioux City, IA
The old, proven, cheap way to put a slab back where it belongs. $4 to $9 per square foot regionally — the reason most Siouxland jobs never need a new pour.
Method
What goes under the slab
Mudjacking — also called slabjacking or concrete raising — pumps a slurry of sand, portland cement and water beneath a settled slab. Ports roughly an inch across are drilled through the concrete in a pattern that spreads the lift. The slurry travels along the underside, fills the void that the settlement left, and then pressure begins to raise the slab.
The operator works the slab up in stages, watching a reference line at the joint, so the panel returns to grade as one plane. Once it is there, pumping stops, the ports are packed with grout, and the joints get sealed.
Cure time is one to three days. The material is heavy — that is the trade-off. On ordinary, reasonably firm ground the added weight is a non-issue and the price advantage is real. Over deeply washed-out or collapse-prone soil, polyurethane foam is often the smarter buy even though it costs more.

Where it fits
Good candidates for slurry
Yes, mudjack it
- • Driveway and approach panels on stable ground
- • Public walk panels with a three-quarter-inch lip
- • Patios, stoops and steps where a day or two of cure is fine
- • Garage floors in older homes with sound concrete
- • Any job where the budget is the deciding factor
Look at foam instead
- • Ground that has washed out badly under the slab
- • Slabs that must carry traffic the same day
- • Very soft or repeatedly saturated soil where weight is the enemy
- • Tight lifts where precise control at small increments matters
Honest version: mudjacking handles the majority of Siouxland residential slabs at the lower price, and we will say so when it does.

Mudjacking questions
- What is mudjacking, exactly?
- A sand-and-cement slurry is pumped under a settled slab through holes drilled in the surface. The slurry fills the void and hydraulic pressure raises the concrete back to grade. It is also called slabjacking or concrete raising — same method, different names.
- How much does mudjacking cost?
- Typically $4 to $9 per square foot as a national and regional range, with most residential jobs landing between $600 and $2,500 and small single-slab work meeting a $300 to $700 minimum call-out.
- How long before I can use the slab?
- Foot traffic is generally fine right away. The slurry cures over one to three days, so vehicles and heavy loads wait until then.
- How long does a mudjacked slab stay level?
- As long as the ground under it stays stable. That is why fixing the water source — the downspout, the grade, the unsealed joint — is part of the job rather than an upsell. A slab lifted over ground that keeps washing out will move again.
