How Improper Basement Drainage Systems Can Increase Radon Levels-and What You Can Do About It
Radon gas is a naturally occurring radioactive gas that can seep into homes through cracks and openings in the foundation. It’s odorless, invisible, and dangerous—linked to thousands of lung cancer cases each year. While many homeowners are aware of the risks associated with radon, few realize that certain basement waterproofing systems can actually contribute to elevated radon levels if not properly designed.
The Hidden Risk: Drainage Systems and Radon Exposure
Basement drainage systems and sump pumps are essential for managing water intrusion, but when installed without airtight seals, they can unintentionally create a pathway for radon gas to enter the home. Systems that leave gaps or open basins expose the basement to the sub-slab environment, allowing radon-laden air to rise into the living space.
This is especially concerning in regions like New Hampshire, where radon levels tend to be higher due to the granite-rich soil. Homeowners looking to protect their property from water damage may unknowingly compromise their indoor air quality if their waterproofing system lacks radon-safe features.
Smart Solutions from Erickson Foundation Solutions
At Erickson Foundation Solutions, we understand the importance of protecting your home from both water and radon. That’s why we offer integrated systems designed to address both concerns simultaneously:
WaterGuard® with RadonSeal
Our WaterGuard® perimeter drainage system is installed below the basement floor to capture water at its entry point. When paired with a radon-sealing flange, it prevents air from the sub-slab from entering the basement, effectively managing water while maintaining radon safety.
TrenchLock™ Surface Drainage
TrenchLock™ is a surface drainage solution that collects water from areas like basement entrances or around immovable utilities. Unlike traditional surface drains, TrenchLock is engineered to allow water in while keeping air out, helping to prevent radon infiltration through exposed drainage channels.
TripleSafe™ Sump Pump System
Our TripleSafe™ sump pump system features three pumps for maximum protection—primary, secondary, and battery backup. Most importantly, it includes an airtight sump liner, which seals off the basin from the sub-foundation air, preventing radon gas from escaping into the basement while ensuring reliable water removal.
Peace of Mind Through Proactive Design
By choosing Erickson Foundation Solutions, homeowners can rest assured that their basement waterproofing system is not only protecting against water damage but also contributing to a healthier indoor environment. Our systems are designed to meet or exceed EPA standards for radon mitigation, giving families peace of mind and long-term protection.
