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.

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

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!
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.
