Active Soil Depressurization Systems Explained
Active Soil Depressurization (ASD) systems help reduce harmful gases in buildings. They stop radon and other soil gases from entering indoor air. These systems use a fan and pipes to pull gases from the ground.
The fan creates a low pressure under the building. This draws soil gases away from the foundation. The gases then vent safely above the roof. This keeps indoor air cleaner and safer.
How Active Soil Depressurization Systems Work
ASD systems use suction to lower soil pressure. A pipe runs from beneath the building to the outside air. A fan in the pipe pulls the soil gases upward. This prevents gases from seeping into the building.
Key Components Of Asd Systems
- Perforated pipe installed under the foundation
- Sealing materials to block gas entry points
- In-line fan that runs continuously
- Vent pipe that releases gases above the roof
Benefits Of Using Active Soil Depressurization
