Concrete
Lifting
Let's get your concrete back to level
Lift your concrete instead of replacing it. The Dwyer Company’s concrete lifting process (also called slabjacking or mudjacking) raises sunken driveways, patios, walkways and garage floors back to their original level, often in just a few hours. We pump a cement-based grout under the slab to fill the gaps left by settling soil and lift it back into place. The process is fast, clean, affordable and permanent. Start with a free inspection and a clear written estimate, with no obligation or pressure.
Signs your concrete is sinking
- A driveway that dips or leaves a lip at the garage door
- Sidewalk or walkway sections that no longer line up
- A patio that slopes toward the house and sends rainwater toward the foundation. If water is getting into the basement, see basement waterproofing.
- A garage floor that has sunk or cracked along a joint
- A gap opening where a slab meets the house. If the house itself is moving, see foundation repair.
- Higher humidity, condensation, or mold spots in one corner
How Dwyer lifts sunken concrete
The right approach depends on the slab and on why it settled. For most homes, the fix is concrete lifting with a cement-based grout, also called slabjacking or mudjacking. Ahead of any work, Dwyer will explain what we recommend and why.
When a slab has sunk but is still in one piece.
We drill small holes through the slab and pump a cement-based grout underneath. The grout fills empty spaces and firms up loose soil first, then gently raises the slab back toward its original level. Once the slab is set, we patch each hole.
When a slab tips water toward the house.
A patio or driveway that has sunk toward the house can send rainwater toward the foundation. Lifting it back to a slope that drains away helps keep water out of your basement. If water is already getting in, we’ll talk through basement waterproofing, too.
When a slab can't be lifted.
Concrete that has dropped 6 inches or more, or that is badly broken up, may need to be replaced. We’ll tell you plainly if your slab falls in that group.
When the house is part of the problem.
A sinking garage floor or a gap where a slab meets the house can point to movement in the foundation itself. In that case, we’ll look at foundation repair first, so the slab has something stable to meet.
What concrete lifting costs
Honest answer: it depends on how much concrete has settled and how big the voids are underneath. The only way to give you a real number is to look.
For most homes, lifting costs a fraction of what tearing out and pouring new concrete would. Our pricing is fixed up front, so there are no surprises when the job is done.
Two things make this easier to plan for:
- The inspection and written estimate are free, so you’ll know your number ahead of any commitment.
- Financing is available if you’d rather spread the cost out. See financing options here.
What the repair does to your home and yard
We drill small holes about 1 to 2 inches across. Most residential jobs need 3 to 5 of them. Our crew pumps the grout, watches the slab rise and then patches each hole. The patches may still show. They’re small and clean. Most residential projects take 2 to 6 hours. Our own Dwyer crew does the work, never subcontractors.

Why concrete sinks across the region
Where your home sits has a lot to do with why its concrete settles. Here’s what tends to be behind it where you live.
The clay hillsides hold water and shift slowly downhill, pulling soil out from under driveways and walks built on the slopes.
Much of Dayton sits over the Great Miami Buried Valley Aquifer, where a high water table softens the soil under slabs in the wet months.
The Bluegrass sits on karst limestone, where water moves fast underground and can carry soil away from under a slab.
In the Ohio River floodplain, the water table often sits close to the surface. Soil that stays wet under a patio or driveway tends to settle.
Older homes in the river towns sit on steep clay hillsides, where slope runoff washes soil out from under walks and steps.
Where the river bottoms rise into the Knobs, runoff collects around the homes below and wears away the soil under their slabs.
