Gas Vent Bollards provide an efficient and economical method of venting ground gases from beneath a building to the atmosphere when connected to a suitable venting system e.g. Ventform or Cellvent.
Vent Bollards are usually installed in locations where alternative venting methods, such as air bricks, cannot be used or where a vent with a high level of free air flow is required.
Used as a method of venting ground gases from beneath a building by positioning at required locations within the external landscaping.
For use with either Ventform or Cellvent panels as part of a passive gas venting system.
