Overview
Mudjacking, sometimes called slabjacking, is the original way to raise a sunken concrete slab. A crew drills holes through the concrete and pumps a mix of water, cement, and fine sand or soil into the space beneath. As the slurry fills the void and builds pressure, it pushes the slab upward until it sits at the right height again.
Compared with polyurethane foam, mudjacking uses larger holes and a much heavier material, and the mix needs time to cure before the slab carries its full load. The trade is availability and efficiency: it is a widely offered method that moves a lot of material quickly, which suits wide, older slabs where a little extra cure time is no obstacle.
In northeast Indiana, the reasons slabs need lifting are well known. Heavy clay holds water, a high water table keeps the ground damp, and freezing and thawing repeat every winter. Those cycles compact soil, open voids, and leave concrete bridging gaps it was never meant to span. Mudjacking fills the gaps and restores support.
Your contractor can help you weigh mudjacking against foam or replacement for your own slab. Both lifting methods target the same problem, filling the space under the concrete, and the better choice depends on the slab's size, condition, access, and how soon you need to use it again.
The number and pattern of holes depends on how big the slab is and how unevenly it has dropped. A good crew walks the concrete with you before drilling. Moving cars, planters, and furniture out of the way beforehand keeps the appointment on schedule.
Mudjacking comes up most on larger, older slabs, such as a long driveway to a rear garage, a wide patio, a barn apron, or a parking pad, where the goal is a reliable, well-tested fix. The density of the slurry can also help where the ground below is loose or was disturbed years ago.
As with any lifting approach, mudjacking works on the soil beneath the slab, not on damage in the concrete itself. If the surface is scaling from road salt or split by many cracks in addition to sinking, the contractor may recommend addressing that separately or replacing the slab.
An older method is not an outdated one. The principle of filling a void and raising a slab has not changed, and a well-run mudjacking job today can perform for many years.
Signs you need mudjacking
Any one of these is worth an on-site evaluation from the contractor we match you with.
- A large slab, such as a full driveway or wide patio, has dropped fairly evenly
- You want a traditional, widely used method for a big job
- A contractor has confirmed the concrete is strong enough to lift as one piece
- Overall project size matters more to you than same-day cure time
- The soil below might benefit from the added density of a cement-based fill
How mudjacking works
Every job starts with an on-site evaluation from the contractor we match you with.
- Step 01Evaluate and plan
The contractor inspects the slab and marks where holes are needed to reach the voids underneath.
- Step 02Drill the holes
Holes roughly one to two inches across are drilled through the slab at each mark.
- Step 03Pump the slurry
A cement-based mixture is pumped beneath the slab, filling gaps and gradually lifting the concrete.
- Step 04Monitor the rise
The crew watches the slab as it moves and adjusts pumping to bring it level.
- Step 05Patch and cure
Holes are patched, and the surface is left to cure before it takes regular foot or vehicle traffic.
Why homeowners choose it
- Decades of track record
- Mudjacking has been used for a very long time, so most concrete contractors know it well.
- Built for big slabs
- Slurry can be pumped in volume, which suits long driveways, wide patios, and farm-style aprons.
- No demolition
- Like foam, it lifts the slab you already have instead of breaking it out and repouring.
- Dense fill
- The heavier mixture can help stabilize ground that is loose or has been disturbed.
- Widely offered
- Because it is so established, many crews across Indiana already offer it.
Typical scenarios
Illustrative examples of the situations homeowners bring to us. They are not specific customer jobs.
Consider a Yoder homeowner whose long driveway has slowly sunk toward the road over a decade. After confirming the slab is sound, a crew pumps slurry through a series of holes and brings the whole driveway back to grade in one working day.
Imagine a Grabill patio made of several connected sections that have dropped by different amounts. The contractor lifts them in sequence so the seams line up, restoring a flat surface without replacing any concrete.
What affects your estimate
We cannot quote a price without seeing the job, but this is what typically goes into a contractor's written estimate.
- 01The total area to be lifted, since slurry is used by volume
- 02How far the slab has dropped and how much material it takes to fill the void
- 03Room for the pump truck and hoses to reach the work area, especially on long driveways
- 04Whether several slabs, like a driveway, walk, and patio, are done in one visit
- 05Drainage or grading recommendations that come out of the evaluation
Keeping it level
A few habits that help a repair hold up over time.
- Keep heavy vehicles off a fresh lift until the contractor says it has cured
- Watch drainage near the slab, because standing water can undermine any fill over time
- Have new cracks or renewed dips checked early instead of waiting
- Ask what lifespan to expect for the soil on your particular lot
- Reseal patched holes if they open up after a hard winter
Fort Wayne weather and your slab
Fort Wayne's clay swells with moisture and shrinks as it dries, and freezing makes wet soil push upward before it settles back unevenly. The extra density of mudjacking slurry is often chosen because it resists some of that movement in soft, damp ground.
Cure time can stretch in cold or wet weather, and freezing temperatures require care with any water-based mix. Contractors may adjust their schedules in winter, so ask how the season will affect your job before you book.
Myths vs. facts
Mudjacking is outdated and nobody does it anymore.
It remains a common, respected method, especially for large slabs where its record and material efficiency matter.
You cannot use the slab for days afterward.
Cure time varies with the mix and the weather, but many jobs are ready for light use well before several days pass. Your contractor will give you a specific timeline.
Mudjacking will crack a slab that is already weak.
A qualified crew evaluates strength first. If the slab cannot be lifted safely, they should recommend a different approach rather than risk more damage.
Mudjacking and foam always cost about the same.
Cost depends on the contractor, slab size, and site conditions for either method. No single answer applies to every job.

Other concrete leveling services
- Polyurethane Foam LiftingA lightweight expanding foam is injected through dime-sized holes to raise a sunken slab, usually in one visit and with very little mess.
- Driveway LevelingSunken driveway panels and garage aprons are lifted back into line, closing lips and low spots without repouring the whole drive.
- Sidewalk LevelingTrip-hazard lips between sidewalk panels are lifted or ground down, so you do not have to replace the whole walk.
- Pool Deck, Patio & Porch LevelingSettled pool decks, patios, and porch slabs are lifted back to level and re-sealed against the house, coping, or steps.
- Garage Floor LevelingLow spots, slopes toward the door, and split slabs inside the garage are lifted back into position with minimal disruption.
