If the slab is sound, lift it — do not replace it
When a slab has settled but is still in one structurally sound piece, tearing it out and repouring is often the most expensive way to solve a problem that leveling can fix in an afternoon. Leveling — also called slab jacking or mudjacking — raises the settled slab back to grade by filling the void beneath it, restoring drainage and removing the trip hazard without the cost, downtime, and cure time of replacement.
We level commercial slabs, sidewalks, approaches, and pads across Hamilton County, and we are straight about when lifting is the right call versus when a slab is too far gone to save.
Why slabs settle here in the first place
Central Indiana's clay soils shrink and swell with moisture, and that movement — combined with poorly compacted backfill, eroded base, or water washing fines out from under a slab — leaves voids the slab eventually drops into. Settlement concentrates where water collects: at downspout discharges, along curb lines, at approach slabs, and where utility trenches were backfilled. Lifting the slab without filling and stabilizing that void just invites it to settle again, so we treat the void, not only the surface.
Mudjacking or polyurethane foam
We offer both lifting methods because each fits different situations:
- Mudjacking pumps a cementitious slurry beneath the slab — proven, economical, and well suited to heavy slabs
- Polyurethane foam injects a lightweight expanding resin — fast-setting, minimal weight added, smaller injection holes, quick return to service
- Foam's light weight is an advantage over weak soils; slurry's mass and economy suit large, heavy slabs
- Either way, the void is filled and the slab is supported, not just nudged up
Where leveling works — and where it does not
Leveling is the right tool for a sound slab that has settled as a unit. It is the wrong tool for a slab that has broken into multiple pieces, lost large sections, or deteriorated through spalling and cracking — lifting a broken slab just produces an uneven, broken, lifted slab. We assess the slab honestly: if it can be saved by lifting, that is the low-cost answer; if it cannot, we will tell you replacement is the better spend rather than sell you a lift that will not hold.
Faster, cheaper, and far less disruptive
The case for leveling is straightforward: it is typically a fraction of replacement cost, leaves no demolition or haul-off, and returns the surface to service quickly — often the same day with polyurethane. For a property manager weighing a trip-hazard correction or a drainage fix against a tight budget, leveling frequently turns a capital-level problem into a maintenance-level one.
What leveling costs depend on
Leveling pricing is set by the area lifted, how much void has to be filled, the method, and access. Polyurethane foam costs more per hole than mudjacking slurry but uses smaller holes, sets in minutes, and returns the area to service fast; slurry is more economical on large, heavy slabs. The cost almost always lands well below replacing the same slab — which is the entire point — as long as the slab is sound enough to lift.
We line-item the slabs by area and method and are explicit about which are leveling candidates and which are not, because lifting a broken slab wastes your money. The assessment is free, and it tells you plainly whether leveling defers a replacement by years or whether the slab is genuinely past saving. For trip-hazard and drainage fixes on a budget, leveling frequently turns a capital problem into a maintenance one.
