In order to adequately vent VOC’s and ground gases from beneath the footprint of a building, vent outlets are required to be connected to the sub-floor venting system.
The selection of the most appropriate vent type is based upon their proposed location, the perimeter wall construction of the building and the required air flow capacity, which in turn dictates the spacing between each vent.
For advice regarding the positioning, spacing and detailing of the perimeter vent outlets, please contact the Cordek Technical Team for further advice.
Consult the table below to assess the suitability of each vent outlet, in terms of location and air flow capacity.
