What system is used to remove soil gases that accumulate beneath buildings?

The Subslab Soil Exhaust System is specifically designed to mitigate the accumulation of soil gases that can build up beneath buildings. These gases can include harmful elements such as radon, methane, and volatile organic compounds, which pose significant health risks if they infiltrate the indoor air.

This system typically operates by creating a negative pressure beneath the building’s foundation. It uses a network of piping installed beneath the slab, which draws these gases out and vents them safely into the atmosphere, away from occupied spaces. The effectiveness of this system relies on correct installation and maintenance, ensuring that it adequately prevents soil gases from entering the building.

In contrast, other options don’t serve this particular function. Flues are primarily designed for venting combustion gases from heating appliances and do not address soil gas concerns. Solar Thermal Equipment is focused on harnessing solar energy for heating purposes, not related to soil gas removal. Air Intake and Exhaust Screens are typically used for ventilation in buildings, preventing debris from entering, but they do not deal specifically with the issue of soil gas accumulation beneath structures.
