Basement Waterproofing in Overland Park, KS

Our Basement Waterproofing Services in Overland Park, KS Include

We install robust interior and exterior waterproofing to prevent water from penetrating the basement of your home. Here are a list of basement waterproofing in Overland Park, KS provided by KC Waterproofing and Foundation Repair.

Interior Basement Waterproofing

We install an interior waterproofing system as a preventative measure, eliminating the possibility of structural damage over time.

  1. Interior Drainage Systems: We install a KCW Drain System to collect water that seeps into your basement. Once it collects water, it directs it to the sump pit, where it can be pumped out of your home.
  2. Sump Pump Systems: We also install a KCW Sump Pump System, which consists of a large sump pit and a high-capacity pump system with a battery backup. Our team installs these sump pumps in your basement to pump water away from your foundation. If you notice standing water or flooding in your basement, our sump pump system is the ideal solution for your home.
  3. Wall Crack Repair: We inject polyurethane into interior basement wall cracks, hardening and sealing the cracks. Depending on the cause of the cracks, our team also suggests other foundation repair methods that better suit your basement’s needs.
  4. Basement Dehumidifiers: We install a basement dehumidifier to maintain the optimal moisture level inside the basement. The dehumidifier helps keep your basement dry, prevent mold, and promote good indoor air quality.

Exterior Basement Waterproofing 

We can also waterproof the exterior of your basement to prevent water intrusion:

  1. Exterior Crack Injection System: To seal cracks on the exterior of your foundation walls, we inject polyurethane resin. This resin expands with water and prevents water from entering.
  2. Downspout Extensions and Exterior Grading: We install downspout extensions that direct rainwater away from your home. We may also correct the grading on your property so that water does not pool around your foundation.
  3. Gutter Covers: We also install gutter covers on your roofs to prevent gutters from getting clogged. This keeps water flowing through the gutters and away from your foundation.
  4. French Drain Systems: We install a French drain system along the exterior perimeter of your home. This system collects water and diverts it away from your foundation so that it cannot enter the basement or crawl space.

Signs You Need Basement Waterproofing

If your basement has never flooded, you might think you don’t need waterproofing. However, you may still be at risk of moisture damage. If you notice these common signs in your basement, it might be time to have your basement inspected.

  • Wall or Floor Cracks: Cracked walls are often the result of moisture and hydrostatic pressure. When contracting and expanding soil puts too much pressure on the walls and floors, cracks begin to form.
  • Musty Smells: Mold and mildew develop in damp areas and cause unpleasant odors.
  • Visible Mold: Basement mold is very common in homes that have water intrusion or leaks.

How Basement Waterproofing Works

Our Overland Park basement waterproofing team begins their basement waterproofing with a thorough evaluation of the moisture levels in your basement. If there’s already severe water damage, we may recommend various strategies to combat this.

Then, our basement waterproofing experts in Overland Park install a subfloor drainage system. This system uses a vapor barrier to direct water into a drain, preventing flooding in your basement. Then, we use a sump pump to remove all excess water. By combining these strategies, we can effectively remove all excess moisture from your basement and keep it from developing any further water issues.

Why Should You Waterproof Your Basement?

Waterproofing your basement has the following benefits:

  • Reduced risk of flooding
  • Reduced overall moisture
  • Enhanced protection for your home

The sub-floor drainage system we install minimizes flooding risks to your structure during heavy rain periods. The system works by diverting water away from your basement to prevent damage. With this system, you don’t have to worry about mold growth or water damage.

Satisfied Customers

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.
Thank you Cam!

Thank you Cam!
Very professional, informative and did a great job cleaning up after the job.
Jeff was very professional and informative. Fortunately we didn't have foundation problems but if we do we know who to call.
Mario was here on time & was very informative about questions I had. A 10 out of 10. Thank you …Mario
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.
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!
