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.
Features
- Available in a wide range of material types and finishes
- Can be positioned at larger centres due to high level of free air flow
- High quality, robust construction
- Elevated vent position to avoid potential for water and / or debris ingress
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.
Applications
Used as a method of venting ground gases from beneath a building by positioning at required locations within the external landscaping.
Suitability
For use with either Ventform or Cellvent panels as part of a passive gas venting system.
