On April 24th, 2018, KC Waterproofing and Foundation Repair and Fernando’s crew went to Raytown, MO for a waterproofing and foundation repair job. When we arrived, the crawl space was bowing inward 11 inches due to drainage issues! We obviously wanted to get this resolved as soon as possible to get the homeowners back to having a safe and comfortable home.

We installed 63 feet of exterior waterproofing to control and resolve drainage and gutter issues. We fix foundation issues from the inside and out–we want to go to the source and make sure that they are resolved. In many cases, walls will bow inwards due to hydrostatic pressure from water pushing on the foundation walls.

Next, we installed 16 plate anchors to stabilize and support the wall and make sure that any bowing was resolved. Plate anchors work to help to bow and leaning walls and to close cracks in foundation walls. The plate anchor is put in from the outside and tightened into place. Plate anchors can also be tightened over time to avoid stress on already fragile walls. There is not much mess and you can easily cover it up when finished.

When we were done, the tape measure showed the bowing wall right at 3 inches (as opposed to 11 inches earlier). Over time, the wall can be straightened even more from the inside. If we tightened it too much, too soon, we could severely damage the wall. After the job, we cleaned up the area, made sure the client was satisfied, answered any questions, and completed the job.

Great service, everyone is friendly and courteous. They do whatever they can to help you. Great company I would recommend to anyone.

Samantha K.

Great team, worked very hard and stayed after hours to install a basement window as they knew a huge storm was on the way. Our basement was super dry following a lot of rain after install/fixing of foundation proving the job was done well! I recommend this company for foundation repair and water proofing to cinder block foundation in old home.

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.

Richard

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.

Mike D.

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.

Kate H.

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.
