fix your sunken concrete with mudjacking
June 9, 2021

Take a look at your sidewalks and driveway. Do they look as beautiful as they once did or have they sunk or raised over time? In many cases, sidewalks and driveways will buckle and cause raised edges that become a trip hazard. If this is taking place on your driveway, it can make it harder to shovel and a bumpy and uneven ride for anyone driving on the slab. Mudjacking is an easy solution that will make your sidewalks and driveway safer and more attractive.

What is Mudjacking?

Mudjacking is the process of injecting concrete beneath a slab (like the sidewalk or driveway) to raise that portion and make it even with the rest of the slab. It is also used to fill voids beneath cement that can be a major safety hazard. The basic process does involve a little mess, but it will be cleaned up before we leave the job site and your cement slabs will be good as new by the time we’re done. This method of repair can be used on all kinds of concrete slabs.

Is Mudjacking Right for My Property?

Most likely! In most cases, mudjacking is the most common option for concrete slab raising and leveling. It’s a tried and tested method that will help you make your sidewalk, driveway, patio, garage, or other surfaces safe and attractive again. The biggest reason you may not be interested in mudjacking is that it does take time to set and it will depend on the weather when it can be done (i.e. not in the rain). If you have a job that needs to be done immediately, this may not be the option for you. However, if this is a regular repair, then mudjacking is most likely the best option for your concrete leveling project!

Are There Any Other Options?

There are lots of other options, depending on your situation. If the concrete is cracked, there may be deeper issues. This is especially true in the case of a slab foundation. It’s very important to get this checked out by a professional, like those at KC Waterproofing and Foundation Repair, because your home’s structural integrity is depending on the stability of that foundation slab.

In cases like this, we may recommend another method to support, stabilize, and level out your foundation. This could include pier systems including slab piers, push piers, or helical piers. Whichever method is chosen will be based on your specific problem and the root cause of that problem. Each case is different, so it’s difficult to say what the exact solution will be without an estimate. Luckily, we offer free estimates that you can take advantage of right now!

How Can I Tell If I Need Mudjacking?

Have you noticed signs of unstable concrete on your property? Sunken concrete in your sidewalks or driveway. Mudjacking can help to stabilize these weak or uneven surfaces to get the concrete level and back to normal. Here are some of the common reasons that mudjacking may be required.

Wet or Dehydrated Soil

Concrete settling occurs when the foundation below the concrete shifts because it can no longer support the weight of the concrete. This typically occurs when the soil expands due to moisture. It can also happen when the soil is dehydrated. Both of these situations can lead to concrete sinking. When this happens, cavities below the slabs cause it to crack or shift.’

Mudjacking, in this circumstance, fills these voids. Holes are drilled into the concrete to access the cavities in the soil, and then the holes are filled by concrete repair contractors with a compound such as a limestone aggregate. They use this material to level the foundation and eliminate faults in the pavement.

Washing Away of Soil

It’s no secret that Kansas City gets its share of serious weather. Significant rainfall, and plumbing leaks, can cause the soil to wash away. When this happens, the ground beneath the concrete shifts, leading to sunken concrete. This lack of support relocates the pavement, causing it to move out of place. The result is a tripping hazard due to unleveled slabs.

An option to consider is completely lifting the slab, smoothing the surface, and re-adding the soil. However, this can be quite costly. Mudjacking offers a very affordable and practical solution.

Instead of lifting and replacing the slabs, it enables you to fill the voids beneath while maintaining the integrity of the existing concrete. In many instances, it is not the concrete that is the issue but rather the foundation.’

Soil That Was Improperly Compacted

Its foundation must be smooth to achieve the ideal surface for patios, pathways, or driveways. The soil must be evenly distributed. Only then, will concrete slabs settle accurately? Poorly compacted soil that is not at its correct grade level will lead to breaks. Over time, the loose soil will form voids in the earth, causing slabs of concrete to crack and shift.’

Concrete repair in Kansas City, particularly mudjacking, can correct the holes caused by loose soil. Adding a suitable compound, like Polypier from Earth Contact Products, to these voids will help to fill the dirt by re-establishing strength in the foundation. With concrete leveling, the appearance of your pathway can be restored.’

Satisfied Customer Reviews

Didn't waste any time. I have a big problem and he told me from the beginning that they couldn't handle it. He helped give me some advice and direction... and did not try to sell me on something he knew they couldn't deliver. I appreciated his upfront honesty and advice.
They are a fantastic company and really went above and beyond to make sure we got the information we needed.
Mario was great! He very informative and helpful! I would highly recommend him!
Mario came out to check the sump pump. After cleaning the pit out and checking both the main and backup pump he wiped everything done and left the area cleaner than when he got there. Very friendly and knowledgeable guy!
Don Derry with KC Waterproofing has been our "go-to" foundation repair specialist since 2005! We have had him to our homes multiple times. The project always wraps up with us having peace of mind. This past time with 14 piers installed, was no exception. His crew was polite and respectful. They cleaned up our property perfectly at the conclusion of the project. I highly recommend this foundation repair company.
Tech was on time completed the repair as necessary, and the experience was great.
We recently had KC Waterproofing out at our home in North Kansas City, and I cannot say enough great things about Ryan Marshall and his team (Austin & Jacob). They worked at our property over the week of July 17/2025 - and absolutely blew us away with their professionalism, work ethic, and transparency.

Ryan took the time to thoroughly explain the problems we were facing, what caused them, and exactly how they were going to fix them. His honesty and willingness to go the extra mile truly set him apart.

Ryan and his assistant worked hard, were respectful of our home, and made sure everything was done right the first time. It's rare these days to find that level of care and craftsmanship. Because of professionals like Ryan, we’ll continue to turn to KC Waterproofing for future needs.

Highly recommend this company—especially if you get the chance to work with Ryan and his crew! When it comes to foundation issues we will always recommend KC Waterproofing. They have been in the business, are trusted, and will do the job correctly.
I recommend KC Waterproofing. They kept me informed as the job went along. They started and ended as they had said. Cleaned up each day before they left. Price was fair and they were able to stabilize walls without excavation which was good so I didn’t have to deal with landscaping. Fran and Julian were professional and easy to work with.
Inspection completed throughly and efficiently. Technician was professional and pleasant.
Mario did great work on our house. Answered any questions we had, was efficient, and courteous. Would definitely recommend.
