Worker Installing Interior Drain Tile

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 Drain Systems 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 Sump Pump Systems, 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

Fast and good!
A sump pump was installed very quickly.
Gerry and Davan were excellent. They protected the house and basement from extra dust and just going in and out to get the tools.
Digging up the yard to install the pipe...they replaced the sod and cleared the extra yard waste. Also they were very friendly with our dog.

Gerry, Davan, and Mario came to check the new installed sump pump. Made sure everything was working.
I'd give everyone 10 stars if I could!!!!

Satisfied Customer Reviews

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!
We recently had foundation repairs with multiple piers and poly-fill. Not only were they professional on-site, but one of the employees even noticed a package sitting outside starting to get rained on so they placed it in my mudroom. They kept me informed through the process and ensured I understood each repair prior to commencing.
Fran was incredible! He was prompt and very knowledgeable about our questions regarding our foundation. He showed us that we already had a bracing system and our foundation was secure. I would recommend him to anyone!
Fran Heisinger came out and gave a detailed and thorough inspection of our foundation. His experience, service and expertise assured us if we needed additional work, his crew and company could do the job. Highly recommend.
We recently used KC Waterproofing to do our foundation, put in an IBeam and jack post, multiple piers. When I say these guys did an excellent job from start to finish… I can’t even express it enough. Very professional. Very clean work. They cleaned up so well you can’t even tell we just had major work done. This was a week and a half project. The entire crew has just been so amazing in this hard time. I will forever recommend and be using them for future projects. I don’t quite remember every one’s name but the ones I do, Cam, Kyle, Jacob, Jesse, Gerry, Connor, you all were amazing and fantastic job. Start to finish!
The team showed up exactly when they were supposed to. They kept us informed with everything they were doing! The entire experience was excellent‼️
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!
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.
We are very happy with the service we received from KC Waterproofing.
We had a very good experience with KC Waterproofing foundation repair on our house in south Kansas City in February and highly recommend you give them an opportunity to look at your foundation for an estimate and any work to be done.
