A drain tile depressurization system is a radon mitigation method for homes with basements or crawl spaces. It involves:
- Utilizing Existing Drain Tile:
- The system connects to the drain tile installed around the basement perimeter.
- Installing Radon Vent Pipe:
- A vent pipe is added to the drain tile, leading to the suction point.
- Negative Pressure Setup:
- A radon-rated fan induces negative pressure under the basement, drawing radon and soil gases.
- Outdoor Exhaust:
- Radon and soil gases are directed through the vent pipe and expelled outside.
- Monitoring and Maintenance:
- The system includes monitoring for ongoing effectiveness and requires periodic maintenance.
This active mitigation method prevents radon from entering living spaces by intercepting soil gases and exhausting them outdoors.
