Signs Your Home Needs Foundation Repair

Seek our professional help immediately if you notice the following signs that your foundation is sinking or settling unevenly:

Uneven, Bouncing, or Sagging Floors

Bouncing, sagging, and squeaking floors indicate that your foundation has settled or the structural beams are rotted.

Cracks in Exterior Walls

Hairline cracks in exterior walls do not signal serious foundation problems. However, if stair-step or horizontal cracks develop on your exterior foundation walls, this may be evidence of foundation movement.

Cracks in Interior Walls or Floors

Cracks on your basement walls or floors allow water to enter your home and may be caused by a weakened foundation. Watch for any cracks that are growing larger, horizontal, or in a stair-step pattern.

Moisture

If your basement or crawl space is damp or has water leaking in, this might be a sign of poor drainage or a compromised foundation. This moisture can lead to mold growth and structural damage.

Common Causes of Foundation Damage

Here are some of the most common causes of foundation failure:

Poor Construction

Inadequate construction practices are a major contributor to foundation issues. When contractors fail to follow industry standards, the result can be a weak foundation that is not able to properly withstand the weight of your home or changes in the soil around your home. Poor site preparation, such as insufficient soil compaction or improper grading, can lead to uneven settling and cracks. Additionally, using substandard materials or flawed designs can weaken the foundation’s ability to support the structure, causing long-term issues.

Soil Erosion

Soil erosion is another common culprit of foundation damage. When the soil surrounding a foundation is washed away by rain, flooding, or poor drainage, it can create voids beneath the foundation. These empty spaces reduce the foundation’s support, causing it to shift or settle unevenly.

Excess Moisture

Excessive moisture around a foundation can significantly impact its stability. Heavy rain, poor drainage systems, or leaks can lead to water pooling around the foundation. This water can cause the soil to expand, exerting additional pressure on the foundation walls. Known as hydrostatic pressure, this force can cause cracks and structural damage over time. Additionally, fluctuating moisture levels can cause soil to shrink and swell, leading to further foundation movement.

KC Waterproofing’s Foundation Repair Services For Gladstone Homes

We offer customized foundation repair solutions, adhere to stringent construction standards, utilize quality materials, and implement sound engineering practices.

Push Piers

Our push pier system involves steel piers driven into the ground around your home and attached to the foundation footer with steel brackets. By transferring the weight of your foundation to stable soil, these piers lift and stabilize your foundation. Push piers are a permanent solution that prevents further settling.

Helical Piers

Helical piers are a versatile solution that can be installed for any home. They provide support and stability, effectively addressing foundation settlement issues.

Wall Anchoring

We install wall anchors to stabilize walls that are bowing inward. This solution pulls walls back into position and provides lasting support. We install carbon fiber straps to brace and strengthen foundation walls that have bowed less than 2″.

Poly Fill

We inject polyurethane foam to lift and level concrete slabs. Compared to mudjacking, poly concrete leveling is quick, strong, non-toxic, and minimally invasive.

Basement Waterproofing

We install interior and exterior basement waterproofing systems to prevent water issues. These systems may include interior drainage flow systems, crack injections, and dehumidifiers. Our exterior repairs include repairing cracks, upgrading gutters and downspouts, and installing exterior French drains.

Sump Pump Installation

We install RapidFlow Sump Pump System™, which includes large sump pits paired with high-capacity sump pumps. Our sump pumps have battery backups so that they can redirect water away from the foundation, even during pump malfunctions or power outages.

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.
