GP® VENT BOX is a ground level ventilation unit designed to work in combination with GP® VOID VENT products to provide passive inflow and outflow of air and ground gas.
The GP® VENT BOX provides a practical and aesthetic method of venting ground gases from beneath a building to the external atmosphere. The vent boxes are designed to be installed within the external landscaping.
GP® VENT BOX is a fully modular system comprising: inlet pipework section, upstand pipework section and cover(s) which are supplied as a modular system, such that the final configuration can be adapted to suit specific depth, varying inlet levels, and base requirement for sealed, or soak away outlets.
GP® VENT BOX are designed to allow the specifier to select the most appropriate vent type based upon performance, aesthetics and functionality. GP® VENT BOX is usually selected where more traditional vent types such as air bricks cannot be used. Usually the GP® VENT BOX is positioned at the designed centres, within the external landscape on opposing sides of the building. Connection to a land drain, attenuation system or soak away prevents the vent box from collecting surface water and the removable lids allow cleaning and maintenance to be carried out when required.
