Why You Need Foundation Leak Repair Services for Your Kansas City Home

Surprisingly, it’s very common to find water leaking from cracks in your basement walls and floors. If it’s not dealt with, it could lead to significant water damage and flooding in your property.

Foundation Leak Repair in Action

At KC Waterproofing and Foundation Repair, we use FlexiShield to fix your Basement or crawl space. Our crack repair system is designed to flex with the foundation and channel water from a leaking wall crack below the slab.

Foundation Wall Crack and Leak Repair in Kansas City Before and After

Top of the Line Basement and Crawl Space Crack Repair

As part of our foundation leak repair services throughout Kansas City, KS, and MO, we use a polyurethane injection system. We have been using this method since 1985. The polyurethane goes in as a liquid and expands, filling the void and causing a flexible seal between the two pieces of concrete. It consists of a strip of FlexiShield drainage matting and textured urethane sealant. It flexes with the foundation as it shifts during seasonal changes. It comes with a 5-year warranty and can be painted, giving you a dry and attractive finish.

Additional Options for Repairing Wall Cracks and Leaks

At KC Waterproofing and Foundation Repair, we always conduct a foundation inspection to discover the root cause of the crack before prescribing a foundation leak repair solution for your Kansas City home. Our basement wall leak repair team will work with you to determine the use of the space and ensure we meet your needs.

Professional organization and representative
Great all around service. Very informative consultation with Hal. Keith and his team were efficient and very clean when installing a new sump pump system. Highly recommend this company.
Matt has done a great job coordinating the projects we have asked KC Waterproofing to do for our company. The Bayer Company seems pleased with the results.
Mario from KC Water Proofing has excellent customer service and he was on time, timely and educated me as the customer for a good understanding of what he fixed on our home. So thankful for Mario!
Had an awesome experience! They installed carbon fiber straps in my basement on 2 walls, installed the proper drainage, new basement windows, cleaned up crawl space and installed a new sump pump—did an amazing job. ABOVE & BEYOND! Super professional, friendly, and fast. Everything was explained clearly, no surprises, and they left the place spotless. We’ve had some rain since and not a single drop inside. Highly recommend if you need basement waterproofing, foundation repair or a sump pump done right!
Mario came out to “service” the sump pump that was installed a couple years ago. Mario was very knowledgeable and courteous.
KC Waterproofing needs to keep an employee like Mario because of these 2 traits.
Prompt, efficient and most importantly effective! The entire team worked with me on a very tight deadline and made it happen! Highly recommend.
Mario did a fantastic job.
