Mudjacking is generally rated at 5 to 10 years. Polyurethane foam is rated at 10 to 15. Those are the numbers, and I am giving them to you first because every page that makes you scroll for them is wasting your time.
Here is the part those pages leave out. The organizations that publish those ranges also classify this work as maintenance, and one of them went back and measured slabs two years after a correct repair and found they had moved anyway. Both halves are true. Only the first half gets quoted.
The short answer, with the numbers
| Method | Published lifespan | The condition attached by the source |
|---|---|---|
| Mudjacking, cement slurry | 5 to 10 years or longer | Depends on the soil conditions and drainage |
| Polyurethane foam | 10 to 15 years or longer | When properly installed and maintained |
Those conditions are not my hedge. They are in the source material, and the people who wrote them are selling neither method.
When somebody asks me this on site, I give them that range and then ask a question back: where does the water from your roof end up? The answer to that moves the number further than anything else we could talk about.
Two agencies, the same numbers
Consumer cost research puts a slurry lift at 5 to 10 years depending on soil and drainage, and foam at 10 to 15.
Now look at what a transportation department says. A Missouri DOT technical brief on slab stabilization estimates 5 to 10 years for cementitious stabilization and 10 to 15 years using polyurethane, with Georgia reporting 5 years or more for cementitious grout.
Same ranges. Different people, different slabs, no shared incentive, and one set measured on highway pavement carrying truck traffic rather than a residential patio.
That agreement is unusual in this trade and it is the reason I will quote those numbers without flinching. It is also the last comfortable thing on this page.
And those same agencies call it maintenance
The Missouri brief does not describe stabilization as a repair that ends. It treats it as a maintenance treatment with a service life, one that requires eventual retreatment.
Then there is the study that actually went back and looked. Oregon DOT instrumented injected slabs and tracked them, and they still moved, up to 0.413 inch over two years. The report's conclusion is one sentence long and it is the most honest thing written about this trade: slab jacking, regardless of method, does not guarantee a static slab.
Read those two together. The numbers are real, and the work is still maintenance, and a correct repair by trained crews on engineered roadway still moved.
A lift lasts as long as the conditions under the slab allow. I did not invent that line to get out of answering. It is what the field data says.
What actually decides it
Four things, and I rank them in this order on every job.
Is the water source still running? Missouri names excess free water among the causes of the erosion that makes voids underneath slabs in the first place. If we fill the void and the downspout keeps emptying beside it, we have bought you time rather than sold you a repair. This is the one that decides more outcomes than the other three combined.
Was the void filled, or only bridged? Material that stops near the injection hole leaves a slab supported in patches rather than across its bearing area. It feels solid on the day. It is a different thing two winters later.
Is anything still growing under there? A live root works to its own schedule and does not care what we pumped in. Lifting over one is scheduling a callback and charging you for the privilege.
Was the slab a candidate at all? More on that further down, because it is the failure people most often mislabel.
Only the first of those four is still yours to change after we drive away. That is why I talk about it before I talk about price.
The annual clock
A repair in this metro is not sitting quietly for 10 years. It is going through a freeze and thaw cycle every winter.
Frost action needs three things at once: soil with enough fine material to be frost susceptible, temperatures cold enough to drive freezing into the ground, and available water. When they line up, ice forms and heaves what is above it. Then the thaw arrives and the subgrade loses bearing capacity, and refreezing after a thaw leaves the material looser than it started.
That cycle is the reason the same repair, done the same way by the same crew, lasts differently on two properties four blocks apart. One of them drains, the other one does not.
What I see in April is rarely new. It is what November had already started.
In clay, it is cyclical rather than finished
Omaha sits on expansive clay, and clay does not hold still. A state geological survey puts expansive soils at up to 20% expansion by volume when they take on water, exerting pressures of 20,000 lb per square foot or greater against slabs and other confining structures, and notes that soils do not regain their original dryness after a property is developed.
Those figures describe how expansive clay behaves generally. They are not a measurement of the ground under your house.
The practical meaning is that movement here is seasonal rather than a single event. In that kind of ground a repair is managed, not completed. I would rather tell somebody at the estimate that their property is one I expect to see again eventually than hand them a number and let them find out.
The ceiling nobody mentions
A lift cannot outlast the slab it lifted.
A maintained concrete driveway is generally reckoned to last 30 years or so, longer if it was poured well and looked after. Set the repair against that.
On concrete with 20 years of service left, a lift rated at 10 to 15 is a genuine question worth working through. On concrete with 8 years left, the rating on the repair is not the binding constraint and the honest conversation is about the slab, not the lift.
So one of the first things I ask is how old the concrete is. If you are trying to work out whether it is worth lifting at all, that question comes before this one does.
About the word permanent
This trade uses that word. Our site does not, neither transportation agency does, and one of them measured slabs moving after a repair that was done correctly.
Nothing under a slab is permanent. Neither is the slab.
I have been asked to put a guarantee in writing more than once and I have said no every time. Not because I doubt the work, but because the part that decides the outcome is the ground, and I do not own the ground. What I will put in writing is what we filled, how far it came up, and what I told you about the water.
Sometimes it was not a short repair, it was the wrong repair
When a lift disappoints, the cause is often that lifting was never the right answer for that slab.
If the surface is flaking, pitting and shedding grit, that is a surface problem the ready-mix industry calls scaling, peeling of the finished surface from freezing and thawing, driven by too little entrained air in the original mix, heavy de-icer on concrete that was not cured properly, or finishing while bleed water was still on it. Resurfacing addresses it. Lifting does not.
Raising a slab restores its position. It does not restore concrete that is worn out.
Same for a panel broken into several pieces, which has stopped behaving like a slab and cannot be raised as one. Neither of those is a lifespan story. They are jobs that should have been sorted differently at the estimate.
I turn down work on both of those most months. It costs me the job and it saves the customer from paying twice, and I would rather have the second conversation than the first. Which is also why which method fits your slab is a separate question from whether it should be lifted at all.
What to do to make yours last
This is the short, cheap, unglamorous section, and it matters more than everything above it.
Get the roof water away from the concrete. Federal guidance puts downspout discharge at least 5 feet from the foundation, or into an underground catchment at least 10 feet out, with lateral pipe pitched at a minimum of 5/8 inch per foot and buried drain pipe at half an inch per foot or steeper for at least 10 feet.
Then reseal the joints so water stops running straight down them, and keep the grade beside the slab running away from it rather than toward it.
Most of that is a Saturday, a tape measure and a tube of sealant. Dealing with the water source is what turns a repair into a lasting one, and I point it out at every estimate whether or not it is work I am being paid for, because the alternative is standing on the same slab with you in three years. If you want the mechanism rather than the checklist, we covered why it settled in the first place separately.
Cost per year, briefly
You can divide the job by the years and get a number. Slurry at $4 to $9 per square foot over 5 to 10 years, foam at $8 to $25 over 10 to 15.
I do not lead with that arithmetic, because dividing a real price by a range that is explicitly conditional produces false precision. It looks like a fact and it is an assumption with a decimal point on it. The full pricing picture is in what it costs per square foot.
Getting a realistic answer for your slab
The honest lifespan answer comes from two things I have to look at: where the water goes, and how much life is left in the concrete itself. Neither is visible from a phone call.
We walk the slab together, I tell you what I see, and if the answer is that the drainage has to change before any of this is worth doing, you will hear that before you hear a price. We would rather say that at the estimate.

FAQ
How long does concrete leveling last?
Published ranges are 5 to 10 years or longer for a cement slurry lift and 10 to 15 or longer for polyurethane foam, and state transportation agencies publish the same ranges for the equivalent roadway work. Both figures come with soil and drainage conditions attached by the sources themselves, so the honest answer is that the range is real and your position within it depends on what is under the slab.
Is concrete leveling permanent?
No, and nobody with data calls it that. Transportation agencies classify slab stabilization as a maintenance treatment with a service life that requires eventual retreatment. A field study that tracked injected slabs found they still moved after two years and concluded that slab jacking of either kind does not guarantee a static slab.
Does polyurethane foam last longer than mudjacking?
Foam carries a longer published range, 10 to 15 years against 5 to 10. That is a published range rather than a verdict, because the conditions under the slab move the result further than the material does. Foam is the right call where weight or cure time decides the job, not because it automatically outlives slurry.
Will my concrete sink again after it is lifted?
It can, and whether it does depends mostly on whether the cause was dealt with. If water is still washing material out from underneath, the slab will move again regardless of method. If the void is filled and the drainage is corrected, the repair holds well. A lift lasts as long as the conditions under the slab allow.
What makes a concrete lift fail early?
Four things, in order: a water source nobody addressed, a void that was bridged rather than filled, an active growing root under the slab, and a slab that was not a good lifting candidate to begin with. The first one causes more early failures than the other three together.
How long does mudjacking last on a driveway?
The same 5 to 10 year range applies, with two driveway-specific factors. Vehicle loading works the base harder than foot traffic does, and driveways usually sit where roof and surface water concentrates. A driveway with corrected drainage will generally sit at the upper end of the range, and one still taking a downspout discharge at the low end.
