What is Slab Settlement?

The foundation of your home supports the structure and ensures that it stays stable and safe. When the foundation is damaged, it can cause major problems throughout the home.

It’s important to note that many of us don’t think about our foundation until we notice a problem. One of the most common problems for slab-on-grade foundations that our team here in Kansas City sees is foundation slab settlement.

Slab settlement occurs in a few specific cases, all involving changes in the soil supporting the foundation. Poorly compacted soil is the main reason that slab settlement occurs. Untouched soil has been compacted for hundreds, if not thousands, of years and is stable enough to hold up foundations.

However, most homes will be built with piering systems or some type of support to assure that the soil will not be disturbed and cause problems with the home’s foundation. When this doesn’t happen, we encounter foundation slab settlement. Many Kansas City area homes and businesses we’ve seen have settlement problems to the point where you may start seeing floors sloping, cracks, or other issues.

Another reason for slab settlement is a change in the amount of moisture in the soil. When the home was first built, the soil may have been perfectly fine to support it. However, over time, dramatic changes in moisture could cause the soil to be unstable. Think about a cabin on the river. Over time, the river may flood, or erosion may occur with water in the soil. This can lead to settlement as the foundation is no longer adequately supported.

Signs of Foundation Slab Settlement in Your Kansas City Area Home

  • Cracks in the wall, especially by doors or windows
  • Cracks in your concrete floor, driveway, or sidewalk
  • Floors “dropping” or pulling away from walls, causing a slight gap
  • “Sticking” doors or windows not caused by excess moisture or swelling

Solutions to Slab Settlement

So you’ve had a professional come out to look at your property, and they’ve determined that you have slab settlement–what now? What are the repair options and slab settlement solutions we offer in Kansas City? Underpinning!

We offer people in and around Kansas City underpinning options that include a piering system, helical piers, or another option based on their specific situation. Underpinning takes your existing foundation and supports it with strong, steel piers that are driven into the ground and then attached to it. The load is transferred to the piers, and the slab settlement issues are gradually corrected.

Whether your foundation repair contractor in Kansas City will utilize steel push piers, helical piers, or another option will be down to your specific situation. However, in general, the difference between steel push piers and helical piers is slight. Push piers are driven deep into the ground and attached, and helical piers are also driven into the ground, but they have a spiral structure to make sure that the hold is stronger. They are then attached to the building’s foundation as well.

Slab settlement is one of the most common foundation repair issues, and we deal with it frequently. We treat our customers like family and will answer any questions you have. After the job, we clean up the work site to look better than when we arrived.

Mario came out to seal a crack on my stairs and fill a settlement crack in the basement. He was very professional and friendly. He did an amazing job and I was very impressed.
Didn't waste any time. I have a big problem and he told me from the beginning that they couldn't handle it. He helped give me some advice and direction... and did not try to sell me on something he knew they couldn't deliver. I appreciated his upfront honesty and advice.
They are a fantastic company and really went above and beyond to make sure we got the information we needed.
Mario was great! He very informative and helpful! I would highly recommend him!
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!
Don Derry with KC Waterproofing has been our "go-to" foundation repair specialist since 2005! We have had him to our homes multiple times. The project always wraps up with us having peace of mind. This past time with 14 piers installed, was no exception. His crew was polite and respectful. They cleaned up our property perfectly at the conclusion of the project. I highly recommend this foundation repair company.
Tech was on time completed the repair as necessary, and the experience was great.
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.
