The Comprehensive Guide to Proper Basement Waterproofing

Waterproofing a basement is a complex task that requires expertise, precision, and the right materials. In this blog, we’ll walk you through the key steps involved in a proper basement waterproofing job, highlighting why professional installation is crucial. We’ll use a real-life example of a project we recently completed in Bowling Green, Kentucky, where we had to correct previous mistakes to ensure the homeowner’s basement remained dry and safe.

The Importance of Professional Waterproofing

Many homeowners attempt DIY solutions or hire contractors who might not have the necessary expertise, leading to inadequate waterproofing. In our featured project, the previous attempt at waterproofing failed because it lacked an interior drainage system, relying instead on exterior solutions. Over time, changes in the environment, such as new driveways and additional structures, can redirect water toward your property, making external solutions insufficient.

Key Steps in Basement Waterproofing

Cleaning and Preparation:
- The first step is to clean the basement walls and floor. This provides a clear view of any cracks or leaks that need attention.
- In our project, we started by cleaning the wall where the previous system failed, preparing it for a new, more effective solution.
Installing the Drainage System:
- Interior Drainage: We install an interior drainage system that captures water at the point of entry. This system directs water into a sump pump, which then discharges it away from the house.
- Dimple Mat and Liner: A dimple mat is placed against the wall, with a liner tucked behind it. Water enters, hits the liner, flows down into the gravel, and then into the drainage system. This method ensures water is managed efficiently and directed away from the foundation.
Concrete Restoration:
- Once the drainage system is in place, we restore the concrete floor. This involves smoothing out the new concrete to ensure a clean, finished look.
- Properly finishing the concrete also helps in maintaining the structural integrity of the basement floor.
Radon Mitigation:
- Kentucky is known for high radon levels, making radon mitigation a crucial part of our waterproofing process. We avoid systems that leave gaps or flanges, which can allow radon gas to enter the home.
- Our sump pump systems are nearly airtight, significantly reducing the risk of radon infiltration.

Why Above-the-Footer Drains Are Ideal

In most of our projects, we use above-the-footer drains, which we find to be highly effective for waterproofing. These systems prevent water from pooling near the foundation, ensuring it is directed into the sump pump for discharge. This method is suitable for about 80% of the structures we work on, but we also have alternative methods for different scenarios.

Real-Life Example: Fixing a Failed Waterproofing Job

In a recent Bowling Green project, the homeowner faced persistent water problems despite having multiple sump pumps and drains installed by previous service providers. These measures were insufficient because the water was not properly controlled. We installed a comprehensive system that managed the water effectively, guiding it to the sump pumps for discharge. The result? The homeowner no longer experiences water problems, even after heavy rains.
