The soil under your foundation expands when it absorbs water and shrinks when it is dry. This cycle can create voids under your home’s foundation, damage the footings, and cause foundation shifts. If you notice any unusual signs of foundation settlement, including cracks, water seepage, and sagging floors, we can help you fix them. KC Waterproofing and Foundation Repair offer comprehensive foundation repair solutions in Gladstone, MO, including piering, wall anchoring, basement waterproofing, poly filling, and sump pump installation.

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.

Great company and extremely easy to work with. Riley was my point of contact and he explained everything very well. After I denied working with them on one property (due to family issues) Riley happily messaged me back when I needed help with another property. The solution was a hard one to figure out, but Riley constantly made suggestions that would hopefully solve the issue without doing too much work that isn’t needed. Riley clearly explained what I needed and don’t and also gave guidance for other issues I had going on regarding window sealing.

Schylur Oakes and his crew were the ones that came and worked on my property. Schylur was extremely personable and friendly. He constantly ran back and forth from the back of the house (where the work was being done) to the front of the house to ring my doorbell and ask me if I was okay with what they were doing, if I wanted them to change anything etc. One moment he even came and asked if I really need the work to be done since there were sprinklers near my basement window and maybe that was the issue instead, not foundation and rain water. I clarified that I don’t even use my sprinklers and I still have water entering but I was glad he even brought it up and checked with me before proceeding. Schylur ended the day by having his crew clean up after themselves and showed me around and told me everything they did.

Only issue I had was payment processing was a pain. It’s 2026, I shouldn’t have to give my card number over the phone for a deposit, just send me a link to a secure site to enter it. How can I trust some random number and voice over the phone? Then for the final payment, having to manually type out and input my card information in to a tablet while it was raining was a slight nuisance. I have my own small business and use Square tap to pay. It’s not that expensive. Come on guys, if I’m using it for my little business, you can afford it for your long standing company. Just my 2 cents.

Camden came and did a thorough inspection of our foundation and explained the findings well. I felt he was honest with his recommendations and did not try to convince us to do something that wasn't necessary.
Will use KC Waterproofing and Foundation Repair again and highly recommend.

This is the second time I've used this company. Great company. They have good employees. Fran did a great job of explaining everything, even the financing. I thought the lending company had great options. When it was time for my French drains to be installed. They came on time and ready. They even did a crawl space protective cover. Great team, they worked well together. Took the whole day but got it all done. Cleaned up well afterwards. The price was reasonable. Jackson explained everything as it went along. Kind, friendly service.

Mario serviced my sump pump today and did a good job. He also replaced tape on my wall shield. He provided excellent customer service and was willing ti come out any time needed or said to call him anytime if I had any questions.
Katlyn E.
KC Waterproofing and Foundation Repair has taken incredible care of my home through multiple visits. Gary and Davan handled my initial sump pump installation and crack repairs, and they were not only skilled but genuinely thoughtful throughout the process. We had a bit of early miscommunication, and instead of brushing it aside, they listened, acknowledged what happened, and adjusted the plan so everything aligned with what I needed.

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

Later on, I had some cracks that needed to be reassessed, and Mario came out to take a look. He was incredibly kind, patient, and thorough, and he did an amazing job with the additional repairs. His calm, reassuring approach made me feel completely taken care of.

I also want to highlight Don, the manager, who is just as kind and committed to making sure customers feel heard and supported. It’s clear this team truly values doing right by people.

I’m grateful for their care and would absolutely recommend them for any foundation repair or waterproofing needs.

Mario was professional and courteous. He got the work done on time and as described. I would call for his services again!

Great price, great work! In just 3 days, Jesse’s team added two sump pumps and over 40’ feet of channeling with the full wall systems. No more towels, fans, and dehumidifier after every big rain storm!
