Blue roof system designed with in-built attenuation capacity for controlled stormwater discharge.
The product can be utilised beneath many types of finish including intensive and biodiverse green roofs, at both roof and podium levels.
Suitable for use in:
ABG blueroof provides stormwater attenuation capacity at source within the roof or podium deck build-up of a development. Suitable for use on inverted or warm roof build-ups & un-insulated decks with waterproofing membranes accredited to zero falls (e.g. BBA accredited or similar).
The system comprises:
1) Restrictor chamber: The control function that restricts the outflow of stormwater from roof or podium area levels to within the calculated discharge rates.
2) Attenuation and drainage void: Water falling on the roof surface percolates through the roof build up to the geocomposite layer. In periods of low rainfall it simply flows through the attenuation void to the restrictor chamber and into the roof outlet. However, when rainfall exceeds the maximum permissible discharge rate the void is utilised to attenuate the excess water and the volume of outflow is controlled by the restrictor chamber.
3) Up to three geotextile filtration / separation layers wrapped around drainage & attenuation layers: Water passing through these layers is filtered to prevent any solid particles from entering the system.
Features and benefits:
- Removal of excavated material required
- Transport and site traffic disruption
- Additional carbon footprint
