If you’ve noticed any of your basement walls bowing inward, or if you’ve seen cracks start to proliferate across one or more walls, you’re already on the clock. Bowing or cracked basement walls are a sign that your foundation is under stress, and if you wait too long to get it inspected and fixed, you may be in for more expensive repairs down the line or a major structural disaster.

The expert team at KC Waterproofing and Foundation Repair offers wall anchors and screws for Overland Park homeowners that ensure the stability and safety of their foundation for years to come. Anchoring your walls in the surrounding soil is an excellent way to repair bowing basement walls, prevent cracks, and keep your basement dry.

Causes of Bowing Walls

Identifying the causes of your bowing walls is the initial step towards finding the right repair solution. Here are some common factors that may cause bowing basement walls:

  • Expansive soil: The soil around your basement can shrink or expand depending on the moisture content. When the moisture content is high, the soil expands and pushes the walls inward. When the moisture content is low, the soil shrinks and causes the wall to fall outward. This seasonal movement may cause the wall to bow and crack gradually.
  • Hydrostatic pressure: Water buildup around the basement can increase the moisture content in the soil. The soil exerts pressure on the walls and pushes them inward, causing bowing walls. Hydrostatic pressure is common in areas with a high water table.
  • Lateral pressure due to heavy objects: When you park heavy objects, such as large construction vehicles, near your basement, the weight of the object may push down on the soil, causing it to press on basement walls. The lateral pressure exerted by soil may lead to bowing walls.
  • Frost heave: During winter, the soil tends to rise as it freezes and settles as the water in the soil gradually melts. This rising and settling movement of the soil may put pressure on the walls, leading to bowing and cracking.

Our Bowing Wall Anchoring Solutions for Overland Park Homes

Our customized solution for bowing walls is a combination of various repair techniques that are customized to address the condition of your home specifically. It may include the following repair solutions:

Wall Reinforcement System

We implement a wall reinforcement solution to reestablish the strength of the bowing basement wall. For maximum effectiveness, we utilize fiber-reinforced polymer, which is considered ten times stronger than steel. The reinforcement system is installed from the inside to minimize the disruptions to the landscape around the basement.

Wall Anchors

We offer plate anchor system installation to support and stabilize the bowing walls in your basement. The anchors used in the process are made of high-strength galvanized steel, so they last for years. This is a quick and convenient installation process that is typically completed in a day. We also provide concrete leveling in Overland Park, if required, as a service.

Bowing Basement Wall Repair Solutions in Overland Park Trusted by Experts

At KC Waterproofing and Foundation Repair, we’ve been installing wall anchors in Overland Park properties for decades, and over that time, we’ve developed our own preferences for quality materials. We use plate anchor systems made of galvanized steel, so there’s no question about their durability or functionality. Also known as “wall washers,” plate anchors work by fastening one plate to the interior of your basement wall and securing another plate in the soil out away from the foundation. The rod extending between them is tightened, pulling the wall back to an upright position and using the strength of the plates and weight of the soil to keep it in place.

Wall Anchors and Screws in Overland Park

Depending on the job, a series of anchors may be necessary to repair a single bowing wall, and we may recommend other solutions as needed. Additionally, if your home’s foundation has settled, piering systems may be an appropriate solution in addition to wall anchors for concrete basement wall repair for your Overland Park home.

Again, don’t wait if you have bowing or cracked basement walls—contact KC Waterproofing and Foundation Repair, Overland Park’s wall anchor experts, for an inspection today and get closer to peace of mind. We also provide Overland Park crawl space repair, basement waterproofing, and foundation repair services in Overland Park.

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.
