Mudjacking in Cincinnati, OH
A well-established slab-lifting method that's been used on driveways, sidewalks, and patios for decades.
Mudjacking is the traditional way to lift a sunken concrete slab. A cement-based slurry is pumped beneath the slab through holes drilled into the concrete, filling voids and gradually raising the slab as the mixture builds up underneath.
Compared to polyurethane foam injection, mudjacking generally uses larger access holes and a heavier fill material, and the slurry needs time to cure before the slab can bear full weight again. Some contractors favor it for larger slabs or budget-conscious jobs where the added weight and cure time aren't a concern.
Your contractor can walk you through whether mudjacking or foam injection is the better fit for your specific slab, soil condition, and timeline-both methods aim to solve the same underlying problem in different ways.
Because mudjacking uses a heavier fill material pumped in volume, the number and placement of access holes depends on the slab's size and how unevenly it's settled. A contractor will walk the area with you before drilling begins, and clearing vehicles or furniture from the work area ahead of time helps the job move quickly.
Mudjacking tends to come up most often for larger, older slabs-driveways and patios poured decades ago-where the goal is a durable, well-tested fix rather than the fastest possible turnaround. It's also a common recommendation when a contractor wants extra weight in the fill to help stabilize a slab over loose or previously disturbed soil.
As with any lifting method, mudjacking works on the soil beneath the slab, not on cracks or damage in the concrete itself. If the slab has significant surface damage in addition to settling, your contractor will let you know whether that needs to be addressed separately or whether replacement makes more sense overall.
Because the technique has been in use for so long, most experienced concrete contractors have performed dozens if not hundreds of mudjacking jobs, which means the process itself holds few surprises. The main variables from job to job are the size of the slab, how far it's dropped, and how easy the site is to access-all of which your contractor accounts for in a written estimate rather than a rough guess.
Homeowners occasionally worry that an older, more established method must mean outdated results, but that's not really how concrete lifting works-the underlying physics of filling a void and raising a slab hasn't changed much, even as material formulations have improved over the decades. A well-executed mudjacking job today holds up just as well as the method's long track record would suggest.

Any one of these is worth an on-site evaluation from the contractor we match you with.
- A large slab, like a full driveway or patio, has settled fairly evenly
- You're comparing lifting options and want the traditional, well-established method
- A contractor has confirmed the slab is structurally sound enough to raise as one piece
- Budget and total job size are a bigger factor than same-day cure time
- The soil beneath the slab could benefit from the added weight and density of a cement-based fill
How Mudjacking Works
Every job starts with an on-site evaluation from the contractor we match you with.
A contractor checks the slab and marks where holes need to be drilled to reach the voids beneath it.
Larger holes-typically 1 to 2 inches-are drilled through the slab at the marked points.
A cement-based slurry mixture is pumped beneath the slab, filling voids and building up pressure to lift the concrete.
The contractor monitors the slab as it rises, adjusting the pumping to bring it back to grade evenly.
Holes are patched and the area is left to cure before it's ready for foot or vehicle traffic-your contractor will confirm the timeline.
Benefits of Mudjacking
Mudjacking has been used to lift concrete for decades, and many contractors are experienced with it.
The slurry can be pumped in volume, making it a practical option for wide driveways or patios.
Like foam injection, mudjacking avoids tearing out and repouring the slab.
The heavier slurry can help stabilize soil that's already loose or previously disturbed.
Because it's such an established method, many concrete contractors already offer it.
Typical Scenarios
Every job is different, but these reflect the kind of situations homeowners bring to us.
A property in one of Cincinnati's older east-side neighborhoods had a driveway that had settled evenly over several years. After confirming the slab was still structurally sound, the contractor used mudjacking to raise the full driveway back toward grade over the course of a day, with the surface ready for light use once the slurry had cured.
A homeowner in Norwood had a poured patio that had settled unevenly across three connected panels over several years. The contractor used mudjacking to raise all three sections in a coordinated sequence, restoring a level surface without replacing any of the existing concrete.
What Affects Your Estimate
We can't quote a price without seeing the job, but here's what typically factors into a contractor's written estimate.
- The total square footage being lifted, since slurry is priced by volume
- How far the slab has settled and how much material it takes to fill the void
- Access to the site for the pump truck and hoses
- Whether multiple slabs (driveway, walkway, patio) are being addressed in the same visit
- Any drainage or grading recommendations that come out of the evaluation
Keeping It Level
A few habits that help a repair hold up over time.
- Avoid heavy vehicle traffic on a freshly lifted slab until your contractor confirms it's cured
- Keep an eye on drainage around the slab, since standing water can undermine any fill material over time
- Have new cracking or renewed settling checked promptly rather than waiting for it to worsen
- Ask your contractor about expected lifespan for your specific soil conditions
- Reseal any patched holes if they open up after a freeze-thaw season
Seasonal Considerations
Cincinnati's clay soil expands and contracts with moisture, and that movement is part of what causes slabs to settle unevenly in the first place. Mudjacking's heavier slurry fill is often chosen specifically because it adds density that resists shifting better than lighter fill in some soil conditions.
Cure time for the slurry can run longer in cold or wet weather, so contractors may adjust scheduling in the winter months. If timing matters for your project, ask your contractor how the season is likely to affect your specific timeline.

Frequently Asked Questions
Questions Cincinnati homeowners ask about mudjacking.
Material and labor costs vary by contractor, slab size, and site access, so there's no reliable general answer. Ask your matched contractor for a written estimate comparing both methods for your specific slab.
