How Much Does Mudjacking Cost?
How much does mudjacking cost? The honest answer depends on three things: how far your concrete has sunk, how big the slab is, and how easy it is for a crew to reach it. Anyone who quotes you a firm number without seeing your driveway or sidewalk is guessing. This guide walks through what actually moves the price up or down, so you can look at your own slab and know which side of each factor you're on. By the end, you'll know exactly how to get a real number instead of an internet estimate.
What Drives the Cost of Mudjacking
Mudjacking works by pumping a slurry of sand, cement, and water under a sunken slab to lift it back into place. The price mostly reflects how much material goes under your concrete and how long the crew spends getting it there. Here are the factors that matter.
How far the slab has sunk
A slab that has dropped an inch needs far less slurry than one that has dropped four inches. More drop means more material pumped underneath, and material is a big part of the bill. You can check this yourself with a tape measure at the joint where the sunken section meets a level one. A small lip you can barely trip over sits at the cheap end. A step-down you notice every time you walk it sits at the expensive end.
The size of the slab
A single sidewalk square is a small job. A two-car driveway is not. Bigger slabs need more injection holes, more slurry, and more time on site. Measure the sunken area in rough square feet before you call anyone. That one number does more to shape your quote than anything else you can tell a contractor over the phone.
Why the concrete settled in the first place
Central Iowa sits on expansive clay soil. It swells when wet and shrinks when dry, and that movement is what drops most slabs around Des Moines. If your slab settled because the soil compacted and is now stable, a straight lift usually solves it. If water is washing soil out from underneath, say from a downspout dumping next to the slab, the contractor may need to fix the drainage too or the concrete will sink again. Solving the cause adds to the price now but saves you from paying for the same lift twice.
Condition of the concrete itself
Mudjacking lifts slabs. It cannot rebuild them. A slab with one or two clean cracks can usually be lifted and then repaired with crack filling. A slab that has crumbled into small pieces cannot be lifted as one unit, and you may be looking at replacement instead. Walk your concrete and count the cracks. A few long cracks are workable. A spiderweb of them across the whole surface pushes the job toward the expensive end, or off the mudjacking menu entirely.
Access for the equipment
Crews need to get a pump and hose to the slab. A driveway facing the street is easy. A backyard patio behind a narrow gate, a fence, and a garden is not. Harder access means more setup time and more labor, and that shows up in the price. Look at the path from the street to your sunken concrete and picture dragging equipment along it. If you can't picture it, expect the quote to reflect that.
Mudjacking versus polyurethane foam
We do both, and they price differently. Mudjacking slurry is a cheaper material, so it often costs less on larger slabs. Polyurethane foam injection uses smaller holes and cures fast, which matters for a garage floor you need to park on soon or a slab carrying heavy loads. Neither is always the right answer. The honest move is to have a contractor look at your slab's condition, the load it carries, and how fast you need it back in service, then price both where both fit.
Cost Factor Table
| Factor | Pushes the price down when… | Pushes it up when… |
|---|---|---|
| Amount of settling | The slab dropped a small amount, under an inch or so | The slab dropped several inches and needs a lot of material |
| Slab size | It's one sidewalk square or a small stoop | It's a full driveway, patio, or garage floor |
| Cause of settling | The soil compacted once and is now stable | Water is washing soil out and drainage needs fixing too |
| Concrete condition | The slab is solid with few cracks | The slab is cracked into many pieces or crumbling |
| Access | The slab sits right off the street or driveway | Equipment must pass gates, fences, or tight side yards |
| Method fit | Standard mudjacking slurry handles the lift | The job needs foam for fast cure time or heavy loads |
How to Get an Accurate Mudjacking Estimate
The fastest path to a real price is a short site visit, but you can speed it up and sharpen it before anyone shows up.
Have this ready when you call:
- Rough measurements. Length and width of the sunken slab, and how far it has dropped at the worst spot.
- Photos. A few shots of the slab, the cracks, and the path a crew would take to reach it.
- The history. How long it's been sinking, whether it's getting worse, and where your downspouts and grading send water.
A good quote should spell out the area being lifted, the method (mudjacking slurry or polyurethane foam), how the injection holes get patched, what happens to existing cracks, and whether any drainage work is included. If a quote is just one number on a page, ask what it covers. Crack repair and drainage fixes left out of a quote have a way of appearing later as extras.
Estimates differ between providers for real reasons. Some companies only offer foam, so every job gets priced as a foam job. Some quote the lift alone and leave crack filling as an add-on. Additionally, some build travel time into the number. Getting two or three quotes isn't about finding the lowest number; it's about seeing which contractor actually explains what your slab needs and prices the whole fix.
Ways to Keep the Cost Down
You can't control the clay under your driveway, but you can control a few things that shape the final price.
- Fix it early. A slab that has dropped an inch costs less to lift than the same slab after two more Iowa freeze-thaw cycles have dropped it three inches. Settling doesn't reverse itself.
- Fix the water problem yourself. Extending a downspout or regrading a small strip of soil next to the slab is a weekend job. Doing it before the lift can keep the contractor's scope smaller and keep the slab from sinking again.
- Lift only what's a problem. You don't have to level every slab on the property at once. Prioritize the tripping hazard on the front walk and the driveway section pushing water toward the garage. The stable patio can wait.
- Compare mudjacking against foam for your specific slab. On some jobs slurry is the budget-friendly option. On others, foam's smaller holes and durability make it the better spend. Ask any contractor to price the method that fits, not just the one they sell.
- Get two or three quotes. Concrete leveling prices vary between companies for the reasons above. A second opinion costs you a phone call and can catch both overpriced quotes and underscoped ones.
Cost Questions People Ask
How does concrete leveling cost compare to replacing the slab?
Leveling almost always costs less than tearing out and pouring new concrete, because you're reusing the slab you already paid for. Replacement adds demolition, hauling, forming, and new concrete to the bill. Leveling only stops making sense when the slab is too broken to lift as one piece.
How much does polyurethane concrete lifting cost compared to mudjacking?
Foam material costs more per job than cement slurry, so polyurethane lifting often carries a higher price on the same slab. What you get for that is smaller injection holes, a lighter material that doesn't add weight to weak soil, and a cure time measured in minutes instead of hours. Whether that's worth the difference depends on your slab, its load, and how soon you need to use it. We'll tell you plainly which one fits.
Is polyjacking cost worth it for a driveway?
Polyjacking is just another name for polyurethane foam lifting, and for driveways it's often a strong fit. Driveways carry vehicle weight, and foam holds up well under load without adding much weight to the soil below. If budget is the deciding factor and the slab is a good candidate, mudjacking can still do the job for less. Get both priced and compare.
Will my homeowner's insurance pay for concrete leveling?
Usually not. Most policies treat settling as normal wear, not sudden damage, so leveling a sunken driveway or walkway typically comes out of pocket. Read your policy or ask your agent before counting on coverage, and budget as if you're paying the full price yourself.
The Bottom Line
The price of lifting sunken concrete comes down to how far it dropped, how big the slab is, why it settled, and how hard it is to reach. No honest number exists until someone measures your slab. Take your measurements and photos, get two or three quotes from local concrete leveling companies, and pick the one that explains the fix, not just the price.
