Abstract
Subterranean gases are removed from a building site by drawing air from ambience and passing the air through an air permeable bed of materials (10) located at the site as a diffused air stream. The subterranean gases become entrained in the diffused air stream which is then exhausted from the bed and removed from the site. A system for practicing the method has slotted air injection conduits (12) interspersed between slotted air extraction conduits (15) embedded in an air permeable bed of materials beneath the building. The system has a blower (18) for drawing air from the extraction conduits and removing it from the site.
