Vent Bollard

Vent Bollard offers an alternative method of ground gas venting to the Vent Box/Circular Vent Gully. The Vent Bollard provides an efficient and economical method for venting ground gases from Vent Mat Systems (such as our Pro Void Vent 25).

For projects where alternative venting methods are required or if there is a higher level of
free air flow required.
