Basements, by design, are imperfect structures. Made of concrete they are built below grade in soil that varies from region to region. Water from the soil leaks into the structure due to pressure. This situation has caused problems for homeowners for over 100 years. Water will enter a basement through the walls, floors and any joints between them. Over the years a wide variety of methods have been developed, by contractors and engineers, to help keep basements dry. As you might expect some methods were more effective than others.
A wet basement is more than an inconvenience. Water can damage finished spaces, encourage mold growth, and make the entire home feel damp. Blackburn designs waterproofing systems around where water enters and how it can be collected and removed. Depending on the home, the solution may include an interior basement drainage system, wall protection, and a dependable sump pump.

- Interior Sub-floor
- Interior Baseboard Systems
- Negative-side Sealant

An interior perimeter drainage system collects water where the basement floor meets the foundation wall and directs it toward the sump pump. The system must be designed to resist clogging and remain accessible for service. Blackburn evaluates the source of the water and recommends a drainage layout suited to the basement.
A secondary issue for sub-floor systems is how to capture water from the walls while hiding the unsightly gap that those systems can have along the perimeter. This gap can collect dirt and debris as well, which is another factor in the clogging of the drain.
The WaterGuard basement drainage system, installed by Blackburn Foundation Repair, is designed to collect water from the basement perimeter while remaining protected from mud and debris. Paired with a properly sized sump pump system, it provides dependable water management for homes across South Dakota, Wyoming, and Nebraska.

WaterGuard Basement Drainage System

Keeping a basement dry has been a challenge for over a century. Contractors have used many methods over the years with varying degrees of effectiveness, though none have been completely successful. Most drainage pipes, the most widely used method, sit at the bottom of the wall and get covered with soil, leading to clogging over time. What good is a system that gets clogged from soil that will then allow your basement to get wet?
Our WaterGuard sub-floor drainage system:
- Is engineered specifically to resist clogging, keeping your basement dry.
- Our special wall flange creates a space between the floor and the wall that captures wall seepage while also keeping dirt and debris from inside the basement out.
- Perforations at the rear of the pipe allow water to flow into the system as well, capturing water that comes up from below too!
- Winner of the CQIA Innovation Prize.
WaterGuard is patented in the United States, Canada and the United Kingdom. Our state-of-the-art WaterGuard system is the best, most permanent, solution to YOUR wet basement!
