Do you have uneven concrete slabs? KC Waterproofing of Grandview can help! If you notice uneven concrete on your property, it is not a problem you should ignore. Uneven concrete is not only unsightly but it can also be a hazard. The problem tends to get worse over time and can lead to costly repair bills down the road if ignored. For concrete leveling in Grandview, MO, trust the experts at KC Waterproofing and Foundation Repair.

What Is Concrete Leveling and Repair?

Concrete repair is the process of lifting and leveling a concrete slab that has sunk and cracked. Weather conditions and other factors can cause the supporting soil beneath the slab to settle or erode. Expansive soil will expand and contract during wet and dry weather patterns, causing the slab to shift, crack, and sink. If the soil beneath the slab wasn’t properly compacted during construction, this can also cause the soil to settle and allow the slab to sink. Soil erosion will leave empty spaces beneath the concrete, which allows the slab to sink as well. Concrete leveling, also known as PolyLift, is a process used to correct an uneven concrete surface by addressing the surface’s foundation. In many cases, concrete leveling or PolyLift is the best option to get the concrete surface back in good condition.

When is Concrete Leveling or Repair Needed?

If you have cracked or unlevel concrete slabs in need of repair on your Grandview property, it poses a tripping hazard and should be repaired right away. Our concrete repair team in Grandview uses an innovative technique called PolyLift to quickly and permanently repair sinking concrete slabs, with little disruption to the surrounding area. PolyLift uses an expanding polyurethane foam, which is injected through small holes drilled into the concrete slab. As the foam expands and hardens, it lifts the slab back into place. The foam is lightweight and will not create further settlement.

Using Technology to Fix Your Concrete

At KC Waterproofing and Foundation Repair, we use the latest technology for concrete leveling in Grandview, MO. We use a state-of-the-art polyurethane product called PolyLift. PolyLift is a foam that expands when applied and permanently fixes the concrete problem. It weighs less than the original mud or new concrete, so it won’t make any sinking problems worse.

To apply this solution, we drill holes in the sunken concrete and add PolyLift until it is raised back to its original level. We use the PolyLift material and method instead of mudjacking because it lasts longer and does not deteriorate over time.

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.
