Do you have slabs of concrete around your home that have sunk and are out of level? It’s easy to get worried and frustrated about these or to just let them get worse until they become tripping hazards or even bigger problems.

However, it’s easy to level out your concrete, so you won’t have to worry about it (or even think about it) any more! Stop wondering if today is the day when someone trips over that raised crack in your sidewalk and gets your concrete back to normal fast when you call us at KC Waterproofing and Foundation Repair and ask about concrete leveling. We provide professional concrete leveling in Olathe, KS.

What is Concrete Leveling?

Concrete leaving is precisely what it sounds like it is. It’s the process of bringing slabs of concrete back up to the level when they have sunk down. It makes all of your concrete flat and straight again, so you don’t have to be concerned about it becoming an eyesore or someone tripping.

There are a few methods we can use when it comes to concrete leveling. We’ll make sure we use the one that is best for you, given your concrete, the earth below it, and your budget.

What Causes Concrete Slab Settlement?

A concrete slab can experience settlement for a wide range of reasons. Here are some of the most common causes of settling or sinking in concrete slabs.

Soil Erosion

When the soil underneath your concrete slab is washed away by water, this can cause voids underneath the slab that allow it to settle. This usually occurs when there is a lot of water runoff in an area due to rainfall, melting snow, or overflowing gutters. If there are cracks and holes in your concrete slab, water can run underneath the slab and cause erosion.

Changes in Soil Moisture

Dry periods can cause soil to shrink, especially if your soil has a lot of clay. However, periods of rainfall will cause the soil to absorb water and expand. These changes in soil moisture can trigger constant movement in the soil, causing settlement and shifting.

Tree Roots

If your property has trees around it, your concrete slab is more likely to shift. As the tree roots grow, they can move the soil beneath the concrete slab, causing it to shift. Tree roots also take up moisture from the nearby soil, which leads to changes in the soil moisture, leading the concrete to settle over time.

Natural Settlement

Soil gets loosened up when it is excavated during the construction process. It can take a couple of years for the soil around your foundation to settle again, especially if it’s not compacted properly during construction.

Do you have concrete panels that have shifted or moved over time? Even a small shift can turn a regular sidewalk or a driveway into a safety hazard. Reach out to us at KC Waterproofing and Foundation Repair to find out how you can get all of your concrete at the same level again with expert concrete leveling services in Olathe, KS.

Most of the time, our concrete levelers in Olathe will use polyjacking to raise concrete panels that have fallen. By pumping earth back under them, we can raise them so they aren’t tripping hazards anymore.

How Does the Polyjacking Process Work?

Polyjacking is a reliable concrete leveling method. It raises and levels uneven or settling concrete surfaces by injecting polyurethane foam underneath the surface. Here’s how it works:

Step 1: Prepare the Site

The first step is preparing the site where the polyjacking process will take place. We will clean the surrounding area and remove any debris to make the concrete easily accessible.

Step 2: Drill Holes in the Concrete

The next step is to drill holes in the concrete. If there are no concerning cracks that require repair, we will drill holes in several places on the concrete surface. The number, size, and placement of holes will depend on your slab.

Step 3: Inject Polyurethane Foam

We will inject polyurethane foam into the holes we drilled in the concrete slab. The polyurethane foam will reach the voids underneath the slab and expand, applying pressure on the slab above. That way, the slab will be lifted and leveled.

Step 4: Finish Up

Once the process is finished, we conduct a post-repair evaluation to make sure your concrete slab is level and stable. We clean all the excess foam and leave behind a clean, even concrete surface.

Fast and good!
A sump pump was installed very quickly.
Gerry and Davan were excellent. They protected the house and basement from extra dust and just going in and out to get the tools.
Digging up the yard to install the pipe...they replaced the sod and cleared the extra yard waste. Also they were very friendly with our dog.

Gerry, Davan, and Mario came to check the new installed sump pump. Made sure everything was working.
I'd give everyone 10 stars if I could!!!!

Camden came and did a thorough inspection of our foundation and explained the findings well. I felt he was honest with his recommendations and did not try to convince us to do something that wasn't necessary.
Will use KC Waterproofing and Foundation Repair again and highly recommend.
Thank you Cam!
We recently had foundation repairs with multiple piers and poly-fill. Not only were they professional on-site, but one of the employees even noticed a package sitting outside starting to get rained on so they placed it in my mudroom. They kept me informed through the process and ensured I understood each repair prior to commencing.
Fran was incredible! He was prompt and very knowledgeable about our questions regarding our foundation. He showed us that we already had a bracing system and our foundation was secure. I would recommend him to anyone!
Fran Heisinger came out and gave a detailed and thorough inspection of our foundation. His experience, service and expertise assured us if we needed additional work, his crew and company could do the job. Highly recommend.
We recently used KC Waterproofing to do our foundation, put in an IBeam and jack post, multiple piers. When I say these guys did an excellent job from start to finish… I can’t even express it enough. Very professional. Very clean work. They cleaned up so well you can’t even tell we just had major work done. This was a week and a half project. The entire crew has just been so amazing in this hard time. I will forever recommend and be using them for future projects. I don’t quite remember every one’s name but the ones I do, Cam, Kyle, Jacob, Jesse, Gerry, Connor, you all were amazing and fantastic job. Start to finish!
The team showed up exactly when they were supposed to. They kept us informed with everything they were doing! The entire experience was excellent‼️
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!
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.
We are very happy with the service we received from KC Waterproofing.
We had a very good experience with KC Waterproofing foundation repair on our house in south Kansas City in February and highly recommend you give them an opportunity to look at your foundation for an estimate and any work to be done.
