VisqueenPro Gas Vent Box

The VisqueenPro Gas Vent Box is the external termination point of the Visqueen gas venting system, releasing collected ground gases safely to atmosphere at the building perimeter. It comprises a base with a 110mm pipe inlet and adjustable feet, allowing it to be levelled and secured within the concrete surround, with the lid held down by locking bolts.

The lid is heel-safe and suitable for use in pedestrian areas, so the vent box can be set into paths, patios and other trafficked ground without creating a trip hazard. Its design also manages surface water at the vent point, reducing the risk of rainwater entering the void beneath and diluting the effectiveness of the system.

Choose from a galvanised steel base (VT020A) or a stainless steel base (VT020B) to suit the exposure and durability requirements of the installation.
