What is Concrete Leveling?

Concrete leveling is the process of bringing sunken concrete slabs back up, so they are level with the other slabs around them. It helps even out sidewalks, driveways, stairs, and more. No matter where your sinking issues occur, we should be able to level your concrete again.

We have a number of tools at our disposal when it comes to concrete leveling. We’ll help you choose the best option for your needs, based on the specifics of your situation and your budget. Then we’ll get to work and get your concrete level again as soon as possible.

How Does Polyjacking Work?

We carry out polyjacking in the following steps:

Step 1: Prepare the Site

We inspect the area to identify uneven sections and any underlying issues. We also check for any cracks or damage on the surface that might need repair. Once we examine the area, we ensure the surface is clean and dry before proceeding with polyjacking.

Step 2: Drill Holes in Concrete

We drill small, precise holes, each about 1 inch in diameter. These holes are strategically spaced to ensure an even distribution of foam under the concrete surface.

Step 3: Inject Polyurethane Foam

Once the drilling is complete, we use specialized tools to inject polyurethane foam under the sinking concrete. The foam is injected evenly in order to fill voids underneath the concrete. We allow it to cure and form a solid base, which lifts the slab back to its original level.

Step 4: Finish Up

Once we properly level the concrete, we finish the repair with a final inspection and cleanup. We inspect your concrete to see if any issues remain unaddressed. If so, we fix them immediately. Then, we remove any debris and leave the site clean and dry.

Mario was super friendly and professional. The job was done quickly. We are very happy with the work and have peace of mind with the warranty provided.
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.
Mario is the best guy they have. Thank you for hearing my concerns and addressing the issue. Appreciate your professionalism.
Great crew (Schylur and Marvin). Very customer focused.
KC Waterproofing and Foundation Repair did an excellent job on my sump pump installation and crack repairs. Gary and Davan were not only skilled but genuinely thoughtful throughout the process. We had a bit of miscommunication early on, and instead of brushing it off, they listened carefully, acknowledged what happened, and adjusted their plan so everything aligned with what I needed.

They brought me in at every step—showing me options for the pump location, explaining the exit pipe decisions, and making sure I felt confident about the work being done. Their friendliness and respect made a stressful home repair feel manageable.

I’m grateful for their care and would absolutely recommend them.
