One repair, two methods, and a straight answer on whether your slab should be raised or replaced. Serving Omaha, Bellevue, Papillion, Council Bluffs and the surrounding metro.
Concrete lifting, concrete leveling, concrete raising and slabjacking are four names for the same job. A slab has dropped below where it was poured, and instead of breaking it out and starting again, material is pumped into the space underneath until the slab comes back up. Mudjacking and polyurethane foam are the two ways of doing it. If you have been searching different terms and getting different answers, that is why. It is one repair, and this page covers it.
Concrete in the Omaha metro settles for reasons that are specific to this area. The soil across most of the region is expansive clay, which swells when it takes on water and shrinks back when it dries out. That cycle runs every year and slabs sitting on it move with it. Winters add freeze and thaw, which works on the same joints and the same weak points repeatedly. Then there is fill: patios, stoops, garage floors and aprons are usually poured on backfill that was pushed against the foundation after construction, and backfill keeps consolidating for years.
Water is the accelerator behind almost every job we look at. A downspout emptying beside a driveway, a sump discharge line running under a walk, a joint that opened up and never got resealed. Water moving under a slab carries the fine material out with it, and once there is a void the slab has nothing left to sit on. This is why we spend time at the estimate looking at where water goes, not just at the concrete itself.
There are two methods and they are genuinely different, not marketing variations. Mudjacking pumps a cement based slurry through larger holes and is well suited to exterior slabs where weight is not a concern and cost matters. Polyurethane foam is injected through small holes, expands in place, cures in minutes and weighs a fraction of what slurry weighs, which makes it the better fit for garage floors, pool decks and anywhere the base soil is already weak. We will tell you which one suits your slab and why.
Most residential lifting work falls into a handful of surfaces, and each one behaves differently. Driveways take vehicle load and usually settle at the apron. Sidewalks settle one panel at a time and create trip lips. Patios tip back toward the house and send water at the foundation. Garage floors drop away from the door threshold. Steps and stoops change riser heights, which is the version of this problem people actually trip on. Pool decks settle toward the water and drain runoff into it.
Lifting is not always the right recommendation and we would rather say so at the estimate. A slab that has broken into many pieces, concrete that is spalling and crumbling from years of de-icer, or a surface that has simply reached the end of its service life will be level after lifting and still be failing. Raising a slab restores its position. It does not restore concrete that is worn out. When replacement is the better value we will tell you that rather than sell you a repair that buys two seasons.
The visit itself is not complicated. We walk the area with you first and show you what has actually moved and by how much, because the slab people point at is not always the one that dropped. Then a small pattern of holes is drilled, material is injected while we watch the slab come up against a level reference, and we stop at the right height rather than the highest possible one. Holes are patched, joints are resealed where they need it, and most areas are back in use the same day.
Concrete leveling cost depends on square footage, how far the slab has to come up, how easy the area is to reach and which method suits the job. Lifting is normally a fraction of what removal and replacement costs, and it avoids the disruption of tear-out, disposal and cure time. We give free on-site estimates because there is no honest way to price this over the phone without seeing what is under the slab and where the water is coming from.
One last thing worth saying plainly. A lift lasts as long as the conditions under the slab allow. If the void formed because a downspout was washing soil out from underneath, and that downspout still empties in the same place afterwards, the slab will move again. We will point out what we see and most of it is inexpensive to fix. Dealing with the water source is what turns a repair into a lasting one. If you have been searching concrete leveling near me and comparing Omaha concrete leveling contractors, ask every one of them that question. A concrete leveling company that quotes the lift and never mentions where the water is going is quoting half the job.
Frequently Asked Questions
The questions we get asked most about lifting and leveling settled concrete in Omaha.
Yes. Concrete leveling, concrete lifting, concrete raising and slabjacking all describe the same repair: filling the void under a settled slab so the slab returns toward its original height. Mudjacking and polyurethane foam are the two methods used to do it, not separate services.
Different companies favour different words, which is why searching each term turns up different pages. If your slab has dropped, you are looking at this repair whichever phrase you typed.
There is no single best method. The right one depends on the slab, and any contractor who offers only one option will tell you theirs is best.
The process is the same in outline either way. We work out which slab actually moved and why, drill a planned hole pattern, inject while watching the slab rise against a level reference, stop at the right height rather than the highest possible one, then patch the holes and reseal joints. For a fuller comparison see mudjacking vs polyurethane foam.
We give free on-site estimates rather than phone quotes, because the two things that set the price are the void under the slab and the water source that created it, and neither is visible from a description.
What actually moves the number:
The comparison worth making is not one method against the other. It is lifting against removal and replacement, and lifting normally sits well below replacement for the same area.
Most of the cost is not material. It is the equipment, the injection process and the judgement about where and how far to lift.
A lift that is rushed or placed badly can crack a slab, raise the wrong panel, or push material out through an open joint. Doing it in controlled increments while checking height as the slab moves takes time, and that time is most of what you are paying for.
Set against replacement, though, leveling is usually the cheaper path. Replacement means breaking out the slab, hauling it away, disposal, forming, pouring and then waiting out cure time before you can use the area again. Leveling skips all of that and most areas go back into service the same day.
It is worth it when the slab itself is still sound and the only thing wrong with it is its position. In that situation you are correcting height on concrete that has years of service left, at a fraction of replacement cost.
It is not worth it when the concrete has reached the end of its life. A slab that is spalling through to the aggregate, crumbling at the surface or broken into several pieces will be level after lifting and still be failing. We would rather tell you that at the estimate than take the job.
The honest test is simple: is the concrete in good condition and sitting too low, or is the concrete itself worn out? The first is a leveling job. The second is a replacement.
Three worth knowing about before you book.
First, the injection holes are permanent. They get patched, but new patch material never matches concrete that has weathered for years, so the marks stay visible on close inspection. Foam uses smaller holes than mudjacking, which reduces this but does not remove it.
Second, leveling does not repair the concrete. Cracks, spalling and worn surfaces are still there afterwards. Lifting changes where the slab sits, not what condition it is in.
Third, it does not fix the cause. If water is still washing material out from under the slab, the void will reform. That is why we look at downspouts, sump discharge and open joints during the estimate rather than just quoting the lift.
Not realistically for a structural slab. The consumer foam kits sold for this are designed for small voids and light loads, and they give you no control over how far a slab rises or where the material travels.
The failure modes are expensive. Too much pressure in one spot cracks the slab. Material finding an open joint escapes instead of lifting. Raising the wrong panel makes a trip edge worse rather than better. None of that is recoverable without professional equipment.
What you can usefully do yourself is the part that decides whether the repair lasts: extend downspouts past the slab, redirect sump discharge, and keep control joints sealed so water stops carrying fines out from underneath.
That depends far more on why the slab settled than on which method was used.
If the void formed because fill was still consolidating and the material properly fills it, the correction holds well and there is no reason to expect the slab to drop again. If water is still running under the slab and carrying soil away, a new void will form and the slab will follow it down, regardless of method.
This is the single most useful thing to understand about the repair. The lift addresses today. Dealing with where the water goes decides how long today lasts, and it is usually the cheaper half of the job.
We carry General Liability and Workers' Compensation insurance and hold a Nebraska contractor registration. You are protected against job-site accidents and unfinished work, and you are dealing with a local business, not a crew passing through.
Omaha's clay soils swell when wet, shrink in drought, and heave during freeze-thaw cycles. Our crews know where subsurface water collects in your neighborhood, so we treat the cause, not just the symptom.
Every job starts with a free, no-pressure inspection and a line-item quote. If the slab is too deteriorated or the base is washed out, we say so. We recommend replacement when lifting is not the right call, because a short-term patch wastes your money.
Most residential lifts are finished in one day. We inject lightweight polyurethane foam that cures fast and leaves no ruts from heavy equipment. You can park or walk on the slab within hours of completion.
Concrete lifting and leveling in Omaha is regulated by the City of Omaha Permits and Inspections Division. Most residential driveway, patio, and walkway repairs require a building permit. Work touching the public sidewalk or curb line also requires a right-of-way permit. Permit fees for minor flatwork typically run from $50 to $100 depending on project size and location, and simple residential reviews usually take 1 to 5 business days. We check your exact scope, prepare the application, and pull the required permit before work begins.
Omaha averages about 30.6 inches of precipitation per year, and winter lows often reach 13 degrees F. Repeated freeze-thaw cycles and clay soil expansion cause slabs to move, crack, and lose support. Wet springs add water to voids under concrete, while dry summers shrink the soil and make leveling less predictable when drainage is poor.
We find April, May, early June, September, and October to be the most reliable windows for polyurethane foam lifting. Soil is workable and not saturated during those months. Lifting is possible in summer, but dry clay may require more material. We will tell you if waiting or replacing is the better value for your situation.

Customer Reviews
Nobody could tell me over the phone if our front slab was worth lifting. Dale came out, tapped the panels, looked at the joints, and had an answer in about ten minutes. Two panels up, one coming out. He was specific about which and why. That specificity was worth more than any quote.
We had basement water after every hard rain for two years. Waterproofing company wanted $8,000. Slabsmith looked at the patio slope and said the grade was sending water straight at the foundation. Lifted it in one visit. Basement has been dry through three rain seasons since.
My husband was convinced we needed full replacement. I called Slabsmith for a second opinion. They assessed every panel separately and said four of the seven could be lifted. We saved close to $4,000. My husband has since recommended them to two people at his office.
