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.

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.

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!
We were very pleased with KC Waterproofing and Foundation Repair. The foundation specialist, Camden Bales, explained the process we would need to fix our foundation. We felt very confident in the work that was going to be completed. The crew, headed by Jackson Kleeman, worked very hard every day and kept us well informed of their progress. They arrived on time every day and cleaned up before leaving each night. They were polite, friendly, and knowledgeable. Overall, we are completely satisfied with the job that they did. When they finished, you couldn’t tell that work had been done. Great job!
Sump pump backup pump activated an alarm so I scheduled a checkup to make sure everything was fine. Mario called before coming and was very polite. He showed up on time and got straight to work, I was not home at the time and asked him to call me with the results. He diagnosed the problem and then called me to run through results and also provide some more info on the pump operation. Very easy to work with, good communication, smart guy. Would use him for service again.
Mario did a great job, he was very professional and nice.
KC Waterproofing did a great job installing a new sump pump and other water mitigation items. Friendly crew, arrived each day as planned and finished in just 2.5 days!
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.
