On April 21, 2018, Keith’s KC Waterproofing and Foundation Repair crew were in Olathe, KS. Mr. Chris Dennis had a settling garage slab that was causing his walls to sustain damage. This is considered a foundation repair because we are repairing the foundation of the garage.

To fix this issue, we first installed four piers, three along the west side of the garage, which had sustained the most settling issues, and one pier on the north side of the garage. In total, the slab had sunk two inches! Three of these piers were standard steel piers and the other one was a 250 ECP, Earth Contact Products pier. Piers are driven deep into the ground into stable soil. A plate is then affixed to the foundation and the two are attached. The weight of the foundation then rests upon the piers and gives it the stability and strength that it was previously lacking.

All in all, everything went well and the customer was satisfied. Before Keith’s crew left, they cleaned up the area, talked with the homeowner about their experience, covered any questions or concerns that they might have, and packed up their gear.

Unfortunately, we don’t have any final photos of the holes we dug for the piers being filled–the homeowner was doing it himself! We love participation! After the issue was resolved, we answered any questions the homeowner had, cleaned up the area, and packed up our equipment and crew.

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.

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.
