What is mudjacking?
Mudjacking is a type of concrete leveling used to lift sunken slabs, like sidewalks or driveways, back into place. A professional typically pumps a slurry mixture underneath the slab, and the pressure from this mixture raises the concrete to its original position. It can be an effective way to repair uneven surfaces without replacing the entire slab.
How do I hire a mudjacking professional?
When looking for a professional to handle your mudjacking project, make sure you complete the following steps:
Verify their license and insurance: A mudjacking pro should have a general contractor's license and general liability insurance to cover any potential damage. Keep in mind that specific requirements vary by region.
Get several estimates: A proper estimate should clearly outline the scope of work, the materials they’ll use for the slurry, labor costs, and a project timeline. Getting at least three quotes is a good way to compare your options.
Read their reviews: Good reviews often mention that the concrete has remained level long after the job was done. Red flags include complaints about the slab sinking again, damage to the surrounding property, or surprise fees.
Look at their portfolios: Check their before-and-after photos. You want to see sunken concrete slabs — like patios, driveways, or walkways — that are level and stable in the “after” shots, with minimal signs of the repair work.
Find out if they have warranties: Many companies offer a warranty guaranteeing their work for a certain period. Ask what the warranty covers and how long it lasts in case the slab settles again.
Ask important questions: Before you hire, ask a few key questions. For example: What materials do you use in your slurry mix? How do you protect the surrounding area during the work? What does your cleanup process involve?
How long does mudjacking last?
A professional mudjacking job can typically last for five to ten years, and sometimes even longer. Its longevity ultimately depends on the underlying soil conditions. If the drainage or soil issues that caused the concrete to sink are fixed, you’ll find it’s a very durable, long-term solution.
What can concrete contractors do?
Concrete contractors can build foundations, structures, driveways, concrete storm drains, raise or level concrete patios and much more. They can handle every step of the process, starting with framing the mold that the concrete is poured into. They then cut, assemble and tie together the rebar, giving the concrete its tensile strength. Finally, they pour the concrete in, mixing and conditioning it to ensure it cures properly. They will also take steps to ensure that no air pockets are trapped within it.

What factors affect the cost of mudjacking?
There are several factors that might impact the cost of this project, including:
Project size and scope: The total square footage of the concrete that needs lifting is a primary cost driver. A small section of sidewalk will naturally cost less than raising an entire sunken driveway.
The extent of the damage: How far the slab has sunk affects the amount of material and time needed. A minor lift is simpler and less expensive than correcting a drop of several inches.
The material used for lifting: Traditional mudjacking uses a slurry of soil and cement. Some pros may also offer polyurethane foam injection (polyjacking), which is a lighter but often more expensive alternative.
Site accessibility: If the area is hard to reach with equipment, it can increase labor time. A front walkway is usually easier to access than a backyard patio with no direct entry.
Labor and project complexity: The number of slabs to lift, the need for extensive cleanup, or drilling through especially thick concrete can all add to the time and effort your project requires.
Can you mudjack yourself?
While it's technically possible, DIY mudjacking can carry risks and errors can cause expensive problems later down the road. The process requires specialized, expensive equipment like a high-pressure hydraulic pump and specific knowledge of slurry mixtures. It's a job best left to experienced professionals.
When does it make sense to hire a mudjacking pro?
Hiring a mudjacking pro makes sense when concrete settling affects safety, drainage, or structural integrity. People often call for mudjacking if they experience the following:
Uneven slabs: Driveways, sidewalks, patios, or garage floors with noticeable sinking or trip hazards.
Pooling water: If poor drainage is causing water to collect near your foundation.
Void formation: Like when soil erosion has created gaps beneath the concrete.
Large areas: Extensive or heavy slabs that require specialized equipment and precise leveling.
Time sensitivity: You need a fast, minimally disruptive repair.
A pro helps ensure proper lift, long-term stability, and avoids overcorrecting or cracking the slab.
