What is Mudjacking? (Definition, Process, and Cost)

Mudjacking is an excellent solution for solving uneven concrete sidewalks and other surrounding concrete areas of the home. Mudjacking is also a cost-effective way to fix a problem with your sidewalk. 

Anchor Foundation has been repairing foundations and concrete around homes for over 30 years. Through experience, we have found methods to improve our customers’ lives while fixing the problem completely. 

Mudjacking is one of those repairs. Simple, fast, and relatively clean mudjacking is a great way to repair your home’s concrete. Mudjacking is versatile and can be used to repair different types of damage. 

Understanding what mudjacking is and how it can be an important repair in your home;s future is the first place to start. 

What is Mudjacking?

Mudjacking is the process of drilling a series of holes into the uneven concrete and pumping slurry into the hole to raise the concrete back to the intended height. There are a few different things to discuss when talking about mudjacking. 

When do I need mudjacking?

Mudjacking can be used at several different times throughout a home’s lifetime. Oftentimes mudjacking will be needed on any concrete surrounding the home. Such as patios, stairs, sidewalks etc. 

All of these problems can be handled with mudjacking and are commonly a quick and easy process.Mudjacking is recommended for several issues because of the versatility and speed at which the repair can be done. 

Trip hazards with uneven concrete

One of the most common signs that mudjacking is needed is trip hazards around the property. From sidewalks to patios, when concrete pathways become uneven, tripping hazards occur. These tripping hazards usually are the first thing a homeowner will notice. 

Drainage issues around the house

Another common sign that mudjacking may be needed is a drainage problem. A trip hazard may not be visible in some cases because it is too close to the home wall. Often this will lead to a build-up of water, and a noticeable drainage problem can occur. 

Inspecting around your home when there has not been rained can also show where drainage problems may be. These low drainage areas can be seen without water by looking at the concrete surfaces around the home. When a drainage problem occurs, the concrete surface will likely be stained and possibly moldy from the standing water previously. 

How does Mudjacking work?

The first part of mudjacking is drilling the holes into the concrete, as stated above. When arriving at the foundation repair team will begin accessing the area of damage. Determining how many spots need to be drilled will vary from job to job. 

Hardly ever will a repair team come out, and only one hole needs to be drilled. Typically holes will be drilled in a series of three to five holes and are two inches in diameter spread across the area that needs to be raised. While holes are being drilled, the topsoil used in the slurry mixture is being sifted. 

What Is Slurry?

The slurry is the mixture that is used in the process of mudjacking.The slurry is what allows the repair to happen and is what is pumped into the pre-drilled holes to raise the concrete.

 The mix of slurry typically is a 3-part mixture. Sifted topsoil, portland cement, and water are the most commonly used materials. 

When the topsoil arrives, there are bits of clay and larger chunks intermixed with the soil. This means that the crew must sift it on-site to ensure the mixture is smooth for the injection process. Making the slurry on-site is standard and allows for more control of the consistency of the mix. 

When mixing the slurry controlling the consistency is the key to the repair, and different types of consistency are needed throughout the repair. This is controlled through the amount of water that is added. 

Water is essential to the mixture process, and the job cannot be done without it. This is why we ask that at all jobs that require mudjacking, water be accessible to the repair team. 

How is the concrete raised?

After mixing the slurry, which has a consistency similar to cookie dough, the slurry is then pumped into the hole drilled earlier. Slowly the concrete will start to rise and then settle again. 

 The process of allowing the concrete to settle continues until the concrete returns to level with no settling after. Although the concrete is raised to the proper elevation (or level), the job is not entirely done. 

While the concrete appears to level outside, the slurry underneath would have small air bubbles that would cause future settling. To prevent this, the slurry is once again pumped into the pre-drilled holes, now with a thinner consistency, similar to pancake batter. 

This high-pressure injection of slurry allows the air bubbles to be filled and a solid slurry base underneath the concrete. After completing this, the holes are filled and cleaned, completing the repair in no more than a day in most cases. 

How much will mudjacking cost?

The cost of mudjacking depends on the size of the job and the time needed to repair it. Add in the materials used in the slurry, and that is the cost. Unfortunately, that number changes from job to job and location to location. However, on average, you can expect to pay between $900-$2,000. 

What can’t Mudjacking fix?

Unfortunately, mudjacking cannot fix everything wrong with a home’s concrete or foundation. 


Potholes are one of those things. Potholes cannot be fixed through mudjacking because slowly, the pothole will come back due to the ground’s resettling in that small area. 


Pools and the foundation of a home are the other two main things that mudjacking cannot fix. For pools, mudjacking is not controllable enough to correctly fix the problem. Something like polyjacking, with foam instead of slurry, would be a better fit. 

Home foundation issues

A home’s foundation cannot be repaired through mudjacking either. This comes from the weight of the home on the concrete. The slurry would not be able to hold the home’s weight, never allowing the home to rise. 

Bell-bottom piers are a better fit for repairing a home’s foundation. Common signs of foundation repair are different than signs that mudjacking is needed, making this fairly easy to tell apart. 

Need to fix your uneven concrete?

Mudjacking is an excellent and affordable way to fix most concrete problems found around your home. A quick and straightforward process that, once complete, will last for years to come. Mudjacking issues around the house add longevity to the home’s surrounding concrete.
