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.

Great company and extremely easy to work with. Riley was my point of contact and he explained everything very well. After I denied working with them on one property (due to family issues) Riley happily messaged me back when I needed help with another property. The solution was a hard one to figure out, but Riley constantly made suggestions that would hopefully solve the issue without doing too much work that isn’t needed. Riley clearly explained what I needed and don’t and also gave guidance for other issues I had going on regarding window sealing.

Schylur Oakes and his crew were the ones that came and worked on my property. Schylur was extremely personable and friendly. He constantly ran back and forth from the back of the house (where the work was being done) to the front of the house to ring my doorbell and ask me if I was okay with what they were doing, if I wanted them to change anything etc. One moment he even came and asked if I really need the work to be done since there were sprinklers near my basement window and maybe that was the issue instead, not foundation and rain water. I clarified that I don’t even use my sprinklers and I still have water entering but I was glad he even brought it up and checked with me before proceeding. Schylur ended the day by having his crew clean up after themselves and showed me around and told me everything they did.

Only issue I had was payment processing was a pain. It’s 2026, I shouldn’t have to give my card number over the phone for a deposit, just send me a link to a secure site to enter it. How can I trust some random number and voice over the phone? Then for the final payment, having to manually type out and input my card information in to a tablet while it was raining was a slight nuisance. I have my own small business and use Square tap to pay. It’s not that expensive. Come on guys, if I’m using it for my little business, you can afford it for your long standing company. Just my 2 cents.
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!

Thank you Cam!
Very professional, informative and did a great job cleaning up after the job.
Jeff was very professional and informative. Fortunately we didn't have foundation problems but if we do we know who to call.
Mario was here on time & was very informative about questions I had. A 10 out of 10. Thank you …Mario
This is the second time I've used this company. Great company. They have good employees. Fran did a great job of explaining everything, even the financing. I thought the lending company had great options. When it was time for my French drains to be installed. They came on time and ready. They even did a crawl space protective cover. Great team, they worked well together. Took the whole day but got it all done. Cleaned up well afterwards. The price was reasonable. Jackson explained everything as it went along. Kind, friendly service.
Mario serviced my sump pump today and did a good job. He also replaced tape on my wall shield. He provided excellent customer service and was willing ti come out any time needed or said to call him anytime if I had any questions.
KC Waterproofing and Foundation Repair has taken incredible care of my home through multiple visits. Gary and Davan handled my initial sump pump installation and crack repairs, and they were not only skilled but genuinely thoughtful throughout the process. We had a bit of early miscommunication, and instead of brushing it aside, they listened, acknowledged what happened, and adjusted the plan so everything aligned with what I needed.

They brought me in at every step—walking me through pump location options, explaining the exit pipe decisions, and making sure I felt confident about the work being done. Their friendliness and respect made a stressful repair feel manageable.

Later on, I had some cracks that needed to be reassessed, and Mario came out to take a look. He was incredibly kind, patient, and thorough, and he did an amazing job with the additional repairs. His calm, reassuring approach made me feel completely taken care of.

I also want to highlight Don, the manager, who is just as kind and committed to making sure customers feel heard and supported. It’s clear this team truly values doing right by people.

I’m grateful for their care and would absolutely recommend them for any foundation repair or waterproofing needs.
Mario was professional and courteous. He got the work done on time and as described. I would call for his services again!
Great price, great work! In just 3 days, Jesse’s team added two sump pumps and over 40’ feet of channeling with the full wall systems. No more towels, fans, and dehumidifier after every big rain storm!
