concrete leveling
January 5, 2022

Whether it’s on your sidewalk or your driveway, a sunken section of concrete can look unsightly and create a major tripping hazard. There are a number of ways to perform a sinking concrete repair. Here are the best ones we’ve found.

Replacing or Repairing Concrete

If you don’t want to bother with one of the repairs below, or if the concrete is cracked or otherwise damaged, the best option might be to repair or replace it. Our experts, who all know how to fix sinking concrete, can make a patch that brings the concrete back to level.

On the positive side, patches take away the tripping hazard quickly and cheaply. However, they don’t look much better than simply leaving the concrete out of level. While our team will blend your patch as much as we can, there’s no way to make it identical to the concrete you already have.

If the concrete has suffered cracking or other damage, you may want to replace it. All of our experts know how to repair sunken concrete in this way. We will help you get the best concrete product for your needs and make sure all is level before we leave.

Mudjacking

Another way of performing a sinking concrete repair is to use mudjacking. In this process, we will drill small holes into your concrete. We’ll inject a “mud” – usually a mixture of sand, water, and slurry – under your sunken concrete. This fills in empty spaces below the concrete, and we keep injecting it until it raises the sunken parts.

Our professionals who know how to fix sinking concrete recommend letting this mud dry and harden for at least 2 days before you drive or walk on it. The minimum cost for bringing out our rig may be more than you want to pay to fix a small patch of sunken concrete. You can always split the cost among neighbors with similar problems, though this takes some effort to organize.

Polyurethane Foam

Finally, we can also inject closed-cell polyurethane foam under your sunken concrete. This foam performs your sinking concrete repair in a way that is similar to mudjacking, but it hardens much faster.

The process for injecting the foam is much the same as with mudjacking. Our team will drill small holes in your concrete, then inject the foam. It will expand and harden, raising your concrete. The closed-cell nature of the foam means that it should not be susceptible to breakdown by water.

Satisfied Customer Reviews

KC Waterproofing sent Mario out to my home to give me an estimate on a new sump pump. Mario was great and answered all my questions. I especially like how transparent he was about all the services they have and what they could do to help improve my system. Would definitely recommend him to others.
He checked everything and was very nice. No problem with the work that was done last winter. Thank you
Mario came and re-checked our foundation numbers from previous piering. He was very knowledgeable, reassuring, and professional. He made sure we got our results quickly and was very responsive to communication. I appreciate Mario’s effort!
KC Waterproofing is a highly professional organization. Their staff is friendly and helpful. Not surprising they’ve been in business for many years.
Hal was professional, courteous, and efficient. When he arrived he said what he planned on doing, how long it would take, and was able to evaluate my basement in an hour, providing several good options for waterproofing, with details on the costs and benefits of each. I highly recommend KC Waterproofing when you look for options.
We called about a crack in the basement wall that would leak after heavy rains. Mario came out and went above and beyond on the repair to where I’ve got complete piece of mind knowing I won’t have any further issues with leaks.
Pleasant experience. Competent and nice crew. I’ll definitely use their services again for any foundation needs
Mario was very helpful on his visit to my home. I was concerned about one of the anchors that was installed this summer. He assured me that all was intact and doing like it is supposed to be doing. Thank you Mario!
Mario and Angel did an outstanding job on my outside drainage problem. Mario also does a great job on keeping my sump pump operating.
