Wichita Concrete Leveling Co
(316) 370-2895Free Wichita quotes for driveways, sidewalks and patios.
Settled driveways, sidewalks and patios lifted back to grade with polyurethane foam injected through 5/8-inch ports, keeping the concrete you already have.
Concrete does not sink because it failed. It sinks because the soil under it moved. Most of Wichita sits on clay-heavy soils that swell when spring storms saturate them and shrink hard during our long, dry Kansas summers. Every cycle, the bearing soil under your driveway, sidewalk, or patio loses a little volume, and the slab follows it down. Add poorly compacted fill around newer foundations in Maize or Goddard, or decades of downspout erosion under an old College Hill walkway, and you get the tilted, cracked flatwork found across Sedgwick County.
Wichita Concrete Leveling Co corrects the problem at its source. We drill 5/8-inch ports through the settled slab, a little smaller than a dime, inject polyurethane foam beneath it, and raise the concrete back to its original grade in controlled stages, checking elevations with a string line or laser level as it rises. The foam is ready for use in about 15 minutes, fills the voids that caused the settlement, and weighs about 4 pounds per cubic foot in Kansas DOT's specification, so it adds little load to the soil below. The math usually favors leveling: Fixr reports that in most cases a new slab costs 50 to 70 percent more than leveling, though HomeGuide notes foam can approach replacement cost on some jobs, which is why every quote starts from measurements. Our working estimates for each kind of job are in the Wichita pricing guide.

A settled driveway slab cracks at the joints, ponds water toward the garage, and scrapes car frames at the apron. We inject polyurethane beneath the low panels and raise them back to grade, restoring drainage and closing the step between sections.
Typical: $700 - $2,200 for most two-car driveways
A raised sidewalk edge of more than half an inch is past what federal ADA guidance accepts as a beveled change in level, and in Kansas the abutting owner keeps the walk in repair. We lift settled walkway sections flush with their neighbors without tearing out serviceable concrete.
Typical: $250 - $800 for most sidewalk and walkway jobs
A patio that settles toward the house sends every rainstorm at your foundation. We lift settled patio slabs back to a slight away-from-house pitch, protecting the basement or slab foundation while making furniture sit flat and doors swing free again.
Typical: $500 - $1,500 for most patios
Garage floors settle at the overhead door line and crack across the middle when the fill beneath them consolidates. We lift the slab back to level, close the gap under the door seal, and fill the voids beneath it so parked vehicles bear on supported concrete again.
Typical: $800 - $2,500 for most garage floors
A settled pool deck creates trip edges beside water, pitches splash-out away from deck drains, and can stress coping and skimmer lines. We lift deck sections back to plane with lightweight foam that will not overload the pool's backfill zone.
Typical: $900 - $2,800 for most pool decks
Not every failing slab has settled yet. Wash-out from broken downspouts, plumbing leaks, or erosion under steps leaves hollow voids that drum when tapped. We pump structural foam into the cavity before the concrete above it cracks and drops.
Typical: $500 - $2,000 for most void-filling work
Every estimate starts with elevations, not guesses. We map the slab's low points with a level and straightedge, state the lift required at each point, and price the job from measured void volume, so you can verify our work against our numbers.
Lifting foam under Kansas DOT's specification weighs about 4 pounds per cubic foot and must be closed-cell and hydro-insensitive; a cement and fly ash slurry runs 90 to 115 pounds per cubic foot in the FHWA's figures. On Wichita's shrink-swell clays, not re-loading the failed soil is the difference between a repair and a repeat.
We quote leveling because it usually wins the math; in Fixr's national figures, a new slab typically runs half again as much as leveling or more. When a slab is beyond saving, crumbling, deeply spalled, or shattered, we say so plainly and you keep your money for the repour.
The ports are 5/8 inch, and the Colorado and Louisiana highway specs give lifting foam 15 minutes to reach 90 percent of its strength. There are no forms, no curing week and no landfill haul.
We measure your slab's elevations, sound for voids, identify the water source driving the settlement, and give you a written price with the target grade stated.
Ports 5/8 inch across go in over the settled area. Two-part polyurethane pumps beneath the slab, expanding in seconds and filling the void from its deepest point outward.
The slab rises in small, controlled stages, with the rise set by the injection rate and watched on a string line or laser level, until it sits flush with adjacent panels and drains the direction it should.
Ports are filled with non-shrink cement, joints get sealant where needed, and we re-check every elevation against the numbers written on your estimate before we leave.
Wichita's housing stock spans many decades, and each era settles its own way. In College Hill, Riverside, and Crown Heights, older homes have walks and stoops sitting on soil that has cycled through a great many Kansas summers, so offset panels and hollowed stoops are common. Mid-century ranches across southeast and west Wichita show driveway and garage-floor settlement as their backfill finishes consolidating. In newer growth areas, Maize, Goddard, northwest Wichita, and Bel Aire, slabs poured on recently graded fill can settle within their first several years, which surprises owners of otherwise new homes.
The engine behind most of this movement is Sedgwick County's clay-rich soil and the climate that works it. Wichita averages 34.31 inches of precipitation a year in the National Weather Service's 1991-2020 normals, concentrated in spring storms and followed by hot, frequently drought-touched summers. Clay swells as it saturates and shrinks as it dries, and that annual volume change pumps slabs downward a little at a time, while freeze-thaw cycles pry open every joint that water reached. Dry stretches sharpen it: the City entered Stage 1 of its drought response plan in January 2023 and still had Stage 1 in effect in October 2026. It is a soil problem on a schedule, and it rewards owners who correct slabs early.
We work throughout the Wichita metro. Inside the city, that means everything from Delano and Historic Midtown to the newer plats past 135th Street West. Around it, we serve Derby, Andover, Haysville, Park City, Bel Aire, Kechi, Maize, Goddard, Valley Center, Mulvane, Rose Hill, and Clearwater, plus Eastborough tucked inside the city itself, and Newton, the Harvey County seat to the north. In the suburbs, settlement tends to show up in driveways and garage floors on subdivision fill; in town, it shows up more often in sidewalks, patios, and stoops. If you are inside Sedgwick County, or in Andover or Newton beyond its line, you are inside our normal service radius and the estimate is free.
Our working estimates for residential concrete leveling in Wichita run $500 to $2,500 for most jobs, from about $250 for a small sidewalk lift to about $3,500 for a large multi-slab project. National cost guides land in the same area: Fixr puts most leveling jobs at $500 to $1,700, and HomeGuide at $700 to $5,000. Replacement is the comparison that matters, and HomeGuide prices a new concrete slab at $6 to $15 per square foot. Pricing follows measured void volume and lift height more than slab size alone, which is why the quote comes from elevations taken on site rather than over the phone.
| Service | Our working estimate |
|---|---|
| Sidewalk section (1-2 panels) | $250 - $600 |
| Front steps or stoop | $300 - $900 |
| Patio (up to ~200 sq ft) | $500 - $1,500 |
| Two-car driveway | $700 - $2,200 |
Our working estimates put most Wichita jobs at $500 to $2,500, with single sidewalk panels from about $250 and large driveways or pool decks up to about $2,800. Fixr's national range for concrete leveling is $500 to $1,700, with most homeowners paying around $1,500. Price follows lift height and void volume, so the quote comes from on-site measurements, free, rather than a guess by square footage over the phone. The pricing guide breaks the ranges out by job.
Both are forms of concrete leveling that lift slabs through drilled ports; the material is the difference. Mudjacking pumps a cement or soil slurry through 1- to 2-inch holes, and the FHWA's flowable fill guide puts slurries like it at about 90 to 145 pounds per cubic foot, depending on the filler; HomeGuide allows 24 hours before light foot traffic after mudjacking. Polyurethane goes in through 5/8-inch ports, weighs about 4 pounds per cubic foot in Kansas DOT's specification, is ready for use in about 15 minutes, and does not re-load the weak soil that caused the settlement.
Sedgwick County's clay-heavy soils swell in our wet springs and shrink hard in dry summers, and that annual volume cycle slowly lowers whatever sits on top. Add compacting backfill around foundations, downspout wash-out, and freeze-thaw working every joint, and slabs settle on a schedule. Dry stretches sharpen the cycle, and Wichita has been in a stage of its drought plan since January 2023.
Oregon DOT's two-year field study found no loss in the foam's compressive strength underground, and the foam does not wash out the way slurry can, so the lift holds as long as the soil beneath it stays put. The honest variable is water: if a downspout keeps eroding the base, settlement can continue around any repair. That is why every estimate we write identifies the water source and the correction that protects the work.
Usually. Foam lifting does not need the warm, dry curing weather a new pour does: the two components are pressurized through a mixing nozzle, and Missouri DOT's slab stabilization brief puts them at 120 degrees F as they combine. Snow cover is the main winter limit, since the slab surface has to be clear to measure elevations accurately before and during the lift. On a hard-freeze day, ask about frozen ground and the product's own temperature limits.
Slab-lifting foam is the same class of material state highway departments put under pavement. Kansas DOT specifies "a high density, closed cell, hydro-insensitive polyurethane material," and Louisiana's specification defines hydrophobic foam as losing no more than 10 percent of its density or strength when injected into water. For the specifics of a given product, ask for its technical data sheet before the work starts. The injection itself goes through the slab and leaves the landscaping beside it alone.
That depends on how many panels move and how far. The bigger schedule difference is the wait afterward. Colorado and Louisiana write 90 percent strength within 15 minutes into their highway foam specifications, while HomeGuide puts light foot traffic at 24 hours and full vehicle use at 2 to 3 days after mudjacking. A new pour waits longer still, a week or more before Wichita's cement contractor guide lets vehicles onto it.
Not if the cause is corrected, and correcting it is part of our scope. The foam fills the void with a closed-cell material that does not wash out the way slurry can, so re-settlement usually traces to water still moving under the slab. We identify that path, downspout, grade, or leak, on every estimate, and we recommend joint sealing so storm water stops re-entering the base. Where water has already hollowed out the base, void filling packs the cavity before it turns into settlement.
Usually, within limits. Slabs cracked into a few large, sound sections lift well; we raise each section to plane and the crack lines tighten. Concrete that is crumbling, deeply spalled, or broken into small pieces has lost its structural integrity, and we will tell you plainly that replacement is the better spend.
Yes. We lift warehouse floors, dock aprons, storefront walks, and parking areas across the Wichita metro, and the trip-hazard math is sharper for a business that invites the public onto its walks. Commercial lifts can be scheduled around business hours so the surface is back in service before customers or freight arrive.
The owner of the abutting property, under K.S.A. 12-1808. Wichita runs sidewalk repairs as an annual City program, and the City's 2021 council briefing says owners get a minimum of 30 days to have a licensed contractor make the repair before the City's on-call contractor does it at the owner's cost. The sidewalk repair guide walks through the notice, the costs and the federal lip thresholds, and sidewalk leveling often clears a cited panel for less than a replacement.
