Our foundation repair methods in Olathe, KS, address a variety of foundation problems, including:
When the floors in your home slope in one direction or appear uneven, this may indicate a foundation issue. Our repair solutions, including pier installation, can efficiently fix the problem.
Foundation problems often cause cracks in the foundation walls and ceilings. Cracks can allow water to seep in and may widen over time.
A sinking foundation can cause serious structural problems throughout your home and must be repaired immediately. If you notice that your foundation is sloping, cracking, or settling unevenly, it’s important to have it inspected immediately.
The problems in your foundation may stem from any of the following causes:
Poor construction practices, such as the use of low-quality construction materials and inadequate soil preparation, impact the strength and stability of a foundation. Such negligence can lead to foundation issues such as water intrusion, cracks, and sinking.
The soil under and around your foundation has to be in good condition to keep your foundation stable. If the soil quality is not good, your foundation may experience problems such as shifting, settlement, cracks, leakage, and bowing walls.
Poor drainage around your property can allow water to pool around your foundation. This generally leads to issues such as cracks, mold growth, pest infestations, and musty odors. These issues can negatively affect indoor air quality and threaten your home’s structural integrity.
Has your foundation cracked, shifted, or moved? The majority of the time, these issues are caused by shifting earth or sand under your house. Leaks in your pipes or damage to your crawl space could also be behind your foundation problems.
We’ll find out what is causing your foundation issues and get started on your foundation repair in Olathe. We won’t quit until you have the solutions you need and until your home’s foundation is stable once again.
We offer the following comprehensive foundation repair solutions in Olathe, KS:
We offer helical piers and push piers to fix sinking foundations. Both of these pier installation systems are permanent solutions to foundation damage and stabilize the structure by strengthening the foundation.
Our wall anchoring system supports leaning or bowing foundation walls. Over time, it brings the wall back to its original position, offering a long-term solution.
Polyfill, also known as polyurethane foam, is a commonly used solution for fixing a settling foundation. It is a cost-efficient and durable repair method in which the polyurethane foam is injected through small holes in the foundation. As it expands, it lifts the foundation back to its original level and stabilizes it.
We use carbon fiber straps to stabilize cracked foundation walls, ensuring their long-term stability. Carbon fiber straps cannot straighten walls, but they do prevent further cracking, bowing, or leaning.
The quality of our foundation work is due to our years of experience and focus on customer satisfaction.

Everyone I’ve interacted with from KC Waterproofing has been a delight. Friendly, professional and hardworking - from our Foundation Specialist Patrick to every member of Schylur’s crew who completed the work. Their clear communication with me throughout the course of the project was very appreciated. The crew clearly enjoys working together as well as the work they are doing, which gives me full confidence in the caliber of the end result. I would contract them again without reservation and happily recommend them to anyone in need of crawl space waterproofing services.
Connor and his crew did an excellent job fixing our foundation. I can't believe they finish it in 5 days. Hardworking and professional crew. I would recommend them to anybody. Even clean up the basement really well.
Connor and his crew did an excellent job fixing our foundation. They finish it in 5 days and we love the result. Left our basement spotless as well. Would recommend them to anybody.
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.
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!
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.
I am extremely grateful for the amazing work done by Gerry Reynolds and his crew at KC Water Proofing! They did an amazing job installing a drainage system, sub pump, and wall wrap. I would recommend them to anyone needing peace of mind in water proofing their sub basement. Thank you for the hard work!
Excellent service and work! I’ve worked with KC Waterproofing and Foundation Repair twice now (for foundation work and most recently window well/waterproofing work). I have been satisfied with their work both times. Always easy to schedule and Recently Riley helped with a quote and was not pushy about moving forward; which was my experience a few years ago too. They don’t take up hours of time to give a quote which I appreciate. The team that did the recent work (main contact was Schuyler) were easy to work with and talk too, very kind. You can tell this group of people works together and works together well. They had a lot of hand digging and they did it very quickly. When an unexpected issue arose (removing some sidewalk) Schuyler laid out the what/why/how plainly in an easy to understand way. They did replace the sidewalk concrete. It was a big job and they got it done in a day and a half and were in high spirits throughout. They cleaned up a lot after the project too, which is appreciated. Schuyler did a final walk-through and answered any questions I had. Pricing was good too, I got another quote that was astronomical for pricing and the other company wasted 3 hours of my time to provide a quote. If I need anything in the future I won’t bother with a second quote as I’ve always had excellent experiences with KC Waterproofing. The support staff is very kind and helpful too, as well as prompt. Overall, excellent experiences; highly recommend!
We had a leak in what we thought was our foundation. Water coming in under our basement floor. Francis Heisinger came and checked it out for us. He could have recommended a French drain that would entail digging, pipes, removing and replacing concrete and lots of money. Being the honest man that he is, he gave us his opinion as to what the problem entailed. Thank you so very much. Should we ever need foundation work done, we will definitely use this company!
