Our Basement Waterproofing Solutions for St. Joseph Homes

Not all water issues are the same, so our team inspects your property’s basement for free. After a thorough inspection, we provide you with the most suitable services to protect your basement from all internal and external water issues. Here, we’ve listed some of our basement waterproofing solutions:

Patented KCW Drain System

We use our KCW Drain System™ as an interior drainage system in your basement. This system collects all the excess water from your basement and removes it regularly. It removes 30% more water compared to other drainage systems available on the market. Our system is functional, comprehensive, and effective compared to other systems in St. Joseph, MO. We install this system to provide your basement with long-term protection from water damage.

Polyurethane Injections

Our technicians use a polyurethane injection system to fill the void between two pieces of concrete in your basement. This system is designed to treat the interior cracks in your basement. We use polyurethane resin to seal exterior cracks and damages. We use FlexiShield to fix your basement cracking issues. Our system prevents water from entering your basement, increasing your basement’s lifespan and preventing further water damage.

Sump Pumps

We install the KCW Pump System, which efficiently pumps out groundwater. Our system has a built-in pump stand, which keeps the dirt away from the sump pump impeller. This system keeps your basement clean and dry and prevents issues like mold, mildew growth, and high humidity levels. We also provide annual maintenance by trained technicians who make sure your system is in good working condition.

Dehumidifiers

Our technicians install a dehumidification system in your basement that controls the humidity level. Dehumidifiers stop mold and mildew growth and keep irritants like allergens, musty odors, and dust away from your basement. We will install energy-efficient dehumidifiers that will help lower your HVAC costs and keep your basement from smelling musty.

Common Causes of Wet Basements in St. Joseph 

In St. Joseph, the winter is snowy and windy, whereas the summer is wet, humid, and warm. These weather extremes often cause excess moisture in basements. Some other common causes of wet basements include the following:

Cracked Foundation

When your foundation is cracked, rainwater, melted snow, and groundwater seep into your basement. If you don’t repair the cracks quickly, they tend to expand and lead to structural damage. It’s essential to repair your cracked foundation to keep your basement from getting wet.

Excess Humidity

Basements often have poor airflow, which leads to high humidity levels. Excessive humidity leads to various issues like mold growth, water damage, and other problems that cause your basement to get wet.

Poor Drainage

When you have a poor drainage system, it leads to a wet basement. When your basement is wet, you may encounter pests, mold, odors, and increased indoor humidity. Poor drainage can also lead to basement flooding during heavy storms or after the snow melts.

Sump Pump Failure

Sump pumps can fail due to storms, power outages, mechanical problems, or a lack of maintenance. If your sump pump is not maintained properly or replaced in time, you may end up with basement flooding.

Standing Water

When your downspouts are blocked, standing water seeps into your basement area. This may eventually cause mold growth as well as damage to furniture and storage. Consider calling KC Waterproofing and Foundation Repair for waterproofing in St. Joseph, MO, to keep your basement dry, safe, and secure. Our technicians will inspect and figure out the causes of your St. Joseph property’s wet basement. We will resolve it using top-edge technology and extensive techniques.

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.
Tech was on time completed the repair as necessary, and the experience was great.
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.
I recommend KC Waterproofing. They kept me informed as the job went along. They started and ended as they had said. Cleaned up each day before they left. Price was fair and they were able to stabilize walls without excavation which was good so I didn’t have to deal with landscaping. Fran and Julian were professional and easy to work with.
Inspection completed throughly and efficiently. Technician was professional and pleasant.
Mario did great work on our house. Answered any questions we had, was efficient, and courteous. Would definitely recommend.
The workers got the work done on time and as described.
Mario was great. Real personable. He was able to explain the process and how it works. Thank you again Mario.
