Concrete Leveling and Mudjacking in Champaign, Decatur, Springfield, IL, and Surrounding Areas
Jack-A-Slab Construction, Inc. raises sunken concrete in Champaign-Urbana, Decatur, Springfield, and the counties around them. The method is concrete leveling, also called mudjacking or slabjacking: we pump grout through small holes drilled in the slab to fill the void underneath and lift the concrete back to its original grade. We work on homes and light commercial properties; most jobs take a few hours, and you can use the surface almost immediately.

What We Raise and Level
A sunken slab is a tripping hazard first and a drainage problem second. We lift:
- Residential: driveways, sidewalks and city walks, patios, steps and entranceways, garage floors, pool decks, and decks.
- Light commercial: parking lot low spots, entrances, sidewalks, garage floors, pool concrete, and foundations.
We also straighten bowed basement walls and install egress windows.

Why Concrete Sinks in Central Illinois
Most settling traces back to the soil, not the concrete. Clay-rich soil in this part of Illinois swells when it’s wet and shrinks when it dries, and winter freeze-thaw cycles keep it moving. Downspouts that discharge next to a slab, poor grading, and leaking water lines wash soil out from underneath, leaving a void the slab eventually drops into.
That’s why one sidewalk panel can sink while the next one stays level. If water is the cause, we’ll tell you during the estimate so the repair holds.
How Concrete Leveling Works
1. Free On-Site Estimate
We inspect the slab at a time that suits you, whether or not you’re home, and send a detailed quote. We can split the quote into sections so you can decide which areas to do first.
2. Drill Small Holes
Holes go through the sunken slab in a pattern set by where the void sits underneath.
3. Pump Grout and Lift
A specialized grout mixture goes under the slab, fills the void, and raises the concrete back to grade.
4. Fill the Holes and Clean Up
We fill the holes and clean up the work area. You can use the surface almost right away.

Mudjacking or Replacement?
Replacing a slab means demolition, hauling, new forms, and a cure period before you can use it. Raising the existing concrete takes a few hours, leaves your landscaping alone, and keeps old concrete out of the landfill. It also costs a fraction of replacement.
Replacement still makes sense when a slab has cracked into pieces or is crumbling. If that’s what we find, we’ll say so.

Frequently Asked Questions About Concrete Leveling in Champaign, IL
How Much Does Concrete Leveling Cost in Central Illinois?
Concrete leveling typically costs a fraction of what it takes to tear out and replace a slab, and the final price depends on the slab’s size, how far it has sunk, and how much grout the void takes. Jack-A-Slab provides a detailed quote after an on-site inspection.
How Long Does Mudjacking Last?
A mudjacked slab can stay level for many years when the soil underneath stays stable. The cause matters most: if water keeps washing soil out from under the concrete, the slab can settle again, so redirecting downspouts and fixing the grading near the slab helps the repair last.
How Long Does Concrete Leveling Take?
Most concrete leveling jobs take a few hours, and the surface is ready to use almost immediately. Larger commercial projects and jobs with several areas take longer.
Is Mudjacking Better Than Replacing Concrete?
Mudjacking is the better choice when the slab is intact and has simply sunk. It costs less, takes hours instead of days, and doesn’t tear up your landscaping. If the concrete is broken into pieces or crumbling, replacement is the better call.
