A sunken driveway, tilted patio, or dropped garage floor does not always mean starting over. We lift and level settled concrete slabs at a fraction of the cost of full replacement.
Foundation raising in Champaign lifts settled concrete slabs back to their original level by pumping material into the voids underneath - most residential jobs are completed in a single day, with the slab accessible again within 24 to 48 hours.
In Champaign, the heavy clay soil expands when wet and shrinks when dry. Over years of seasonal movement, that creates gaps beneath slabs - driveways, patios, garage floors, and porch pads - and the concrete gradually settles or tilts. The result is uneven surfaces, cracks, and drainage problems that get worse every winter. Before committing to full replacement, many homeowners find that lifting the existing slab is the more practical answer.
Foundation raising pairs naturally with concrete cutting when a section needs to be removed before lifting work can begin, or when drainage improvements require cutting a channel in the adjacent slab.
Stand at one end of your driveway, patio, or garage floor and look down its length. If it looks like a ramp or one side is noticeably lower, the slab has settled unevenly. In Champaign, this often happens after a wet spring followed by a dry summer as the clay soil goes through a full shrink-and-swell cycle.
If standing water collects against your home after rain, the ground has likely shifted enough to redirect drainage toward the house. Champaign's flat terrain makes this especially common, and it is both a sign of existing settlement and a warning that more is coming if drainage is not corrected.
When a foundation shifts, door and window frames shift with it. If a door that used to swing freely now drags on the floor, or a window no longer latches, that is worth having a contractor look at. This is especially relevant in older central Champaign neighborhoods where homes have had decades of freeze-thaw cycles.
Small hairline cracks are normal, but if you run your hand across a crack and feel a lip - one side sitting higher than the other - the slab has settled unevenly. That step is a trip hazard and a structural concern. Diagonal cracks or cracks wider than a quarter-inch are also signs of meaningful movement.
We assess each job before recommending a method. For most residential slabs in Champaign, mudjacking - pumping a cement-and-soil slurry beneath the slab - is a reliable and cost-effective approach. For jobs where curing speed matters or the slab is in a high-traffic area, polyurethane foam injection is the better choice. Foam cures within an hour rather than 24 to 48 hours, and it weighs far less, reducing future stress on the soil. When a slab is too far gone to raise effectively, we will say so directly and point you toward foundation installation as the next step.
Every project includes a full assessment of the drainage around the slab, not just the lifting itself. Champaign's flat terrain and clay soil mean that if water keeps pooling in the same spot, the repair is likely to be temporary unless the drainage issue is addressed at the same time. We walk you through both problems and give you a written price for the full scope before any work begins.
Best for large residential slabs where cost efficiency matters and overnight curing is not an obstacle.
Ideal for driveways or garage floors where same-day access is needed, or where minimizing added weight on the soil matters.
For slabs that are level but have hollow spots underneath - filling the void prevents future settlement before it becomes a visible problem.
After lifting, holes are patched and visible cracks are addressed so the finished surface is clean and ready to use.
The Drummer and Flanagan soil series that run through much of Champaign County are among the most clay-heavy in Illinois. Clay soil absorbs moisture and swells, then shrinks back as conditions dry out. That repeated movement beneath slabs is the primary reason foundation settling is so common here - and it does not stop after one cycle. Champaign also sees frost depths of 30 to 40 inches in a cold winter, which means water that works its way under a slab can freeze, expand, and push the slab upward - then drop it unevenly when the ground thaws. Both forces are working against your concrete year after year.
Homeowners in Urbana and Savoy face the same soil conditions as Champaign proper, and we handle foundation raising across the entire service area. Homes built in the 1940s through 1970s - a large share of the central Champaign housing stock - are now old enough that original slabs have gone through many seasons of movement. The good news is that most of these slabs are still structurally sound enough to raise rather than replace, which saves a significant amount of money and keeps the project to a single day. For more information on permitting requirements, the City of Champaign Building Safety Division is the right place to start.
We ask a few basic questions about where the problem is and roughly how large the affected area is. You will hear back within one business day to schedule your on-site assessment - no commitment required at this stage.
We walk the affected slab with you, check the slope, look for cracks, and assess how water drains around the foundation - because drainage is often part of the problem. This visit takes 30 to 60 minutes.
You receive a written price before any work begins. If the City of Champaign requires a structural permit for your job, we pull it and include the cost in the estimate - no surprise fees after the fact.
The crew drills small holes, pumps material under the slab, and patches the holes before leaving. Most residential jobs finish in two to four hours. We walk the finished area with you before we go.
We will come to your home, assess the situation, and give you a written price - no obligation, no sales pitch.

The clay-heavy Drummer and Flanagan soils of Champaign County behave differently from soils in other parts of Illinois. We account for seasonal movement patterns and drainage in every assessment - not just the slab itself - so the lift lasts as long as possible.
Foundation work has a reputation for vague estimates that grow once the crew arrives. We give you a written price after the on-site assessment, and that price does not change unless the scope of work changes - and if it does, we tell you before we proceed.
Some contractors lift slabs that should have been replaced. We will tell you when raising is the right fix and when replacement makes more sense - so you spend your money on the solution that actually holds, not the cheaper option that fails again in two years. The Concrete Foundations Association outlines the standards we follow for this kind of work.
Champaign Concrete has worked on homes across central Champaign's older neighborhoods and the newer subdivisions on the south and west sides - two very different housing situations that both present foundation raising needs. Whatever your home's age or location, we show up with the right approach for your specific slab.
When a section of slab needs to be removed before lifting work can begin, or a drain channel needs to be cut nearby, our cutting crew handles it first.
