Abstract (en)
[origin: EP0546864A1] Gas-venting apparatus comprises a precast concrete chamber (11) with separate base (12), cover (13) and annular wall (14) which are sunk into the ground beneath a building to collect gases therefrom. The gas permeates into the chamber through peripheral inlet apertures (16) and is vented through a vent duct connected to a peripheral outlet aperture (15). The vent duct opens to the exterior of the building or into the roof void and an impermeable membrane layed beneath the floor of the building prevents gases from rising into the building itself. <IMAGE>
