Radon-Compatible Basement Waterproofing System in Hamilton, Ohio
Challenge
A homeowner contacted us for help with water intrusion in their basement — a concern made more complicated by the fact that they already had a radon mitigation system in place. They needed a waterproofing solution that would not only keep the basement dry but also preserve the airtight environment needed for their radon system to work properly.
Radon is a naturally occurring radioactive gas that rises from the soil. It's invisible and odorless, but prolonged exposure can pose serious health risks. Radon mitigation systems rely on maintaining negative pressure under the slab and keeping indoor air sealed from the soil — something water intrusion can easily compromise.
Solution
To create a waterproofing system that complements the radon setup, we installed a suite of specialized products built with vapor control in mind:
-
100 ft of Radon WaterGuard®: This interior drainage channel is custom-built without the traditional wall flange, ensuring it doesn't compromise the vapor barrier or allow radon to leak into the living space.
-
TrenchLock™ Drain System: We installed TrenchLock around the base of the water heater. This airtight drainage system includes a float-ball mechanism that remains sealed under normal conditions but opens to allow water through if a leak occurs. It’s a great safeguard against future water heater failures and helps keep the basement dry without compromising radon protection.
-
SuperSump® with UltraSump® Battery Backup: This sump system ensures reliable water removal even during power outages. The UltraSump battery backup adds peace of mind in heavy rain or storm conditions.
-
108 ft of BriteWall® Panels: These clean, white wall panels help direct wall seepage into the drainage system and also act as part of the basement’s vapor seal. They’re sealed at the top to prevent radon gas from passing through, maintaining a controlled environment behind the panels.
-
SaniDry™ Sedona Dehumidifier: This compact, high-capacity unit helps control humidity in the basement, improving air quality and reducing mold risk — both of which are essential for maintaining a safe, healthy environment in a radon-sensitive home.
The Result
The homeowner now has a dry, protected basement that works hand-in-hand with their radon mitigation system. By reducing hydrostatic pressure and sealing all potential vapor pathways, the waterproofing system improves the performance and reliability of their radon setup, while also protecting the home from water damage and air quality concerns.
