Airwall Technology

Airwall Example

Earth Science Partnership Airwall Technology is a method of ground gas containment and remediation. It involves controlling the movement of ground gasses and vapours by manipulating the air pressures and flows within the ground. This is done by installing a series of air injection points into the ground to a depth which will have maximum effect on the ground gas, and blocking off primary flow pathways. The pressure can be controlled so it directs ground gasses towards a venting point, where the gasses can be extracted for treatment.


In the first commercial application, Airwall was implemented at a site where methane concentrations were at 25% and where existing traditional barriers had failed. Following installation and rapid modification of the ground gas regime, over 400 residential properties were constructed under the protection of the Airwall (and continue to be).
