Concrete leveling Project in Action

What is Concrete Leveling (aka PolyLift?)

Look at your property in Kansas City across KS and MO. Do you see uneven concrete slabs that have sunk or risen over time? Your sidewalks, driveway, or porch slabs are the usual suspects. In Kansas City across KS and MO, concrete leveling or lifting, also known as PolyLift, is a solution used to correct an uneven concrete surface by altering the surface’s foundation.

Along with not looking as nice as they used to, raised concrete points, like uneven sidewalk slabs, become a tripping hazard to all who cross them. There’s a solution. In most cases for Kansas City, KS, and MO properties, concrete leveling or PolyLift is the smartest option for uneven concrete slabs.

Utilizing updated technology for your PolyLift project

At KC Waterproofing and Foundation Repair, we use a state-of-the-art polyurethane product called PolyLift. PolyLift is an expanding foam that will permanently fix your concrete problem and weigh less than the original mud or new concrete so that it won’t compound the sinking problem.

We drill a series of holes in your sunken concrete and add the PolyLift until it is brought back up to the original level. It’s important to note that the setting time of a concrete leveling project is important, so you need to avoid the rain. We always put our customers first, so we schedule your concrete leveling project around the weather to ensure your solution gets done right the first time. We are more than basement waterproofing. Let us help with your concrete leveling projects in Kansas City.

Causes of Slab Settlement

Slab settlement can be caused by soil that was not properly compacted, expansive soils, or soil erosion, among other factors. As time goes on, the ground beneath the concrete slab may experience a lack of moisture that will cause it to compress as it dries out, or it may receive too much moisture, causing it to expand. If the soil isn’t compacted during construction, the weight of the concrete can cause the soil to sink, which allows the slab to sink as well. When the soil beneath the slab erodes, it will leave pockets beneath the slab, which also causes slab settlement. Any of these situations can cause sinking and foundation cracks on your Kansas City property.

Professional Concrete Repair in Kansas City

Unlevel and cracked concrete isn’t only unsightly, but it can be hazardous. Fortunately, with the help of our team in Kansas City, MO, uneven slabs can be quickly and permanently addressed with an innovative technique called PolyLift. We will drill small holes into the concrete to inject a polyurethane foam that quickly expands and hardens, lifting the slab into its proper position. The foam is lightweight and won’t contribute to further sinking of the soil. PolyLift is a cost-effective solution to concrete repair in Kansas City and can be performed quickly and with minimal disruption to your property.

What Is Interior Slab Leveling?

Slab leveling is an efficient and effective method that uses a polyurethane foam called PolyLift™ to lift and level uneven concrete surfaces. Our crew uses this state-of-the-art solution to level interior concrete slabs by injecting PolyLift foam through tiny holes that are drilled into the slab. The foam quickly expands and hardens, restoring the concrete slab to its correct, level position and providing permanent support beneath the slab.

The Importance of Leveling Interior Slabs

Mario came out to seal a crack on my stairs and fill a settlement crack in the basement. He was very professional and friendly. He did an amazing job and I was very impressed.
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.
