Method and system for protecting buildings from subsurface gases
First Claim
1. A method of removing subterranean gases from a building site having a plurality of slotted air induction conduits in fluid communication with ambience embedded in an air permeable bed of materials beneath a building and a plurality of slotted air exhaust conduits embedded in the air permeable bed of materials, wherein air is drawn out of the air exhaust conduits thereby drawing ambient air into the air induction conduits and through the bed of air permeable materials to entrain subterraneous gases in the air stream as it passes through the bed.

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.
