Concrete Leveling in Fort Wayne, IN
A sunken slab is usually sound concrete sitting on ground that settled or washed out. Lifting it takes a few hours and costs a fraction of tearing it out. It is also the wrong call when the slab is broken up or the surface is gone, and you should hear that before anyone drills a hole.
Typical range: $3 to $7 per square foot for mudjacking, $6 to $16 for foam concrete lifting. Small jobs carry a minimum charge.

How does concrete leveling work?
The first job is finding out why the slab moved, since the lift will not last if the cause is still there. Then:
- Mark the pattern. Holes are laid out a few feet apart, starting at the low point and staying back from the edges, where a slab can snap.
- Drill. About the size of a dime for foam, one to two inches for mudjacking.
- Fill the void. Material goes in until it meets resistance. A slab can have more empty space under it than the drop at the surface suggests.
- Lift in short shots. The operator moves from hole to hole while a second person watches the joint with a level.
- Stop at grade. Over-lifting cannot be undone, so good operators stop a hair low.
- Patch and seal. Holes are grouted, and the joints around the panel are caulked so water stays out of the base.
Leveling is also called concrete lifting, slab jacking or concrete raising. They are the same service.

Is foam concrete lifting or mudjacking better?
Weight is the real difference. Slurry weighs about as much as the soil it replaces, so on soft fill it adds to the load that caused the sinking. Foam weighs a few pounds per cubic foot. On the other side, foam is priced by the pound, and a deep washout under a stoop swallows a lot of it.
Either method needs a slab still in one or two solid pieces.
| Factor | Foam concrete lifting | Mudjacking | Tear out and replace |
|---|---|---|---|
| Hole size | About 5/8 inch | 1 to 2 inches | None, new slab |
| Material weight | Very light | Heavy, like soil | New stone base and concrete |
| Ready for traffic | Often within the hour | Usually the next day | About 7 days for cars |
| Relative cost | Middle | Lowest | Highest |
| Fixes surface damage | No | No | Yes |
| Best for | Soft soil, garage and basement floors | Large voids under sound slabs | Broken, scaled or thin slabs |

How much does concrete leveling cost in Fort Wayne, IN?
Lifting is priced on the slab area and on how much material the void takes, which nobody knows exactly until the first hole is drilled. A fair estimate gives a price for the expected amount and a unit price if the void turns out larger. Ask for both.
| Work | Typical range | What it covers |
|---|---|---|
| Mudjacking | $3 – $7 per sq ft | Drilling, slurry, hole patching |
| Foam concrete lifting | $6 – $16 per sq ft | Drilling, polyurethane foam, hole patching |
| Typical residential job | $600 – $2,000 | A few driveway or sidewalk panels, or a stoop |
| Void fill without lifting | Priced by the job | Foam or slurry under a slab that has not dropped yet |
| Joint and crack sealing | Priced by the job | Backer rod and flexible sealant |
| Panel replacement | $10 – $17 per sq ft | Saw cut, tear-out, new base, new concrete |

Why do concrete slabs sink in Fort Wayne?
Look at where the low spot is and the cause is usually close by:
- Against the house. The soil dug out for the basement was pushed back loose. Walks, stoops and the end of the driveway by the garage sit on it and follow it down.
- Beside a downspout. Roof water runs under the slab edge and carries fine soil away with it.
- Over an old trench. A sewer, water or gas line was dug in and the trench was never compacted.
- At a joint that rocks. Water gets in through the open joint, freezes, and pumps soil out a little more each time a car crosses it.
A slab tipped toward the foundation matters for more than tripping. It sends every rain straight to the basement wall. A fair number of wet basements in Allen County are fixed, or at least much improved, by raising one walk so it drains the right way. The rest of that subject is under basement waterproofing in Fort Wayne.

When should a sunken slab be replaced, not lifted?
Some honest limits. A lifted slab is still the old slab: the color, the cracks and the worn surface come up with it. Cracks that were tight may open slightly as the panel moves, and they get sealed afterward. If what bothers you is how the concrete looks, lifting will not change that.
A drop of half an inch at a sidewalk joint can be ground flush for less than a lift. A drop of four inches at a stoop can still be lifted if the stoop is solid. Size of the drop matters less than the condition of the concrete.
Interior floors need a second look. A basement or garage floor that has sunk along the wall is usually loose backfill and lifts well with foam. A floor that slopes because the whole foundation is settling is a different problem, and filling under the slab hides it without fixing it. That is sorted out at the inspection. See foundation crack and wall repair, sump pumps and French drains for the water side, or the Fort Wayne foundation repair home page.
What else do Fort Wayne homeowners ask about concrete leveling?
Is there concrete leveling near me in Allen County?
Yes. Concrete leveling is done in Fort Wayne, New Haven, Huntertown, Leo-Cedarville, Aboite and Waynedale, and in Auburn. Text a photo of the low spot with a tape measure showing the drop and you can usually get a ballpark before the visit.
How long does concrete leveling last?
Often many years when the cause is fixed along with it. Extend the downspouts, regrade so water runs away from the slab, and keep the joints caulked. If water keeps washing out the base, any lift is temporary.
Is concrete leveling done in winter?
Not outdoors on frozen ground. Frost holds the slab at a false height, and it settles again in spring. Most exterior lifting around Fort Wayne is done from April through November. Basement and heated garage floors can be done any time.
Will the patched holes show?
A little. Foam leaves patches about the size of a dime and mudjacking about the size of a golf ball. They are filled with gray grout that weathers closer to the slab color over a season or two.
Can a sunken garage floor be lifted?
Usually, if it is in large sound pieces. Foam is the common choice in a garage because the holes are small and the car can go back in the same day. A floor that has dropped along the foundation wall is checked for a void under the whole edge.
