When your concrete is out of level around your home, it can create tripping/falling hazards and look unsightly. While these problems can be frustrating, they are actually quite common, and there are a number of ways to address them.

If you need concrete leveling, reach out to us at KC Waterproofing and Foundation Repair today. We’ll work with you to fix your concrete as soon as possible, so you won’t have to worry about it anymore.

What is Concrete Leveling?

Concrete leveling is exactly what it sounds like. It’s the process of bringing your concrete all back to the same level, so you have smooth transitions between the separate pieces once again.

There are a number of ways to achieve concrete leveling, and our experts will use the very best method for your needs. If you have options, we’ll let you know what they are so you can choose the one that is best for your home, your budget, and your needs.

How Does Polyjacking Work?

Here is how we carry out polyjacking repairs:

Step 1: Prepare the Site

We begin the process by assessing the damaged concrete to determine any underlying problems. To prepare the site, we remove obstacles that may cause interruptions during the repair process.

Step 2: Drill Holes in the Concrete

Our repair experts will drill holes in the sinking concrete surface. The holes are usually less than 1 inch in diameter and are strategically drilled across the sinking slab. These small holes allow the polyurethane foam to be injected underneath the surface.

Step 3: Inject Polyurethane Foam

After drilling, we inject polyurethane foam into the void beneath the sinking slab through the drilled holes. Our repair technicians use specialized tools to inject the foam precisely. Since the foam hardens quickly and forms a solid base, we carefully monitor the injection process to avoid any damage. Once the foam solidifies, it brings the concrete slab back to its original, level position.

Step 4: Finish Up

We finish the repair process with a post-repair inspection. We examine the site thoroughly to check for any issues that remain unaddressed. Once the final site inspection is complete, we clean up and remove any debris that was generated during the repair.

Satisfied Customers

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!!!!

Satisfied Customer Reviews

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.
