Description

ABG blueroof provides stormwater attenuation capacity at source within the ballasted / paved roof construction of a development.


The system comprises:

  • Restrictor chamber: The control function that limits the volume of water flow from the roof or podium areas to the agreed discharge rates.
  • Attenuation and drainage void: Water falling on the podium deck surface percolates through the blue roof build up to the geocomposite layer. In periods of low rainfall it simply flows through the attenuation voids to the restrictor chamber and into the drainage outlet. However when rainfall exceeds the calculated maximum permissible discharge rate, the void is utilised to attenuate the excess water and the outflow rate is controlled via the restrictor chamber.
  • Up to three geocomposite drainage and attenuation layers with integral geotextile wrap: Water passing through this layer is filtered to prevent any solid particles / debris from entering the system.


Features and benefits:

  • Controlled storage and release of storm water in line with SuDS best practice / legislation
  • Reduction in roof penetrations and the number of rain water outlets (RWOs) required
  • Zero fall; no need to screed to fall
  • SuDS schemes; provides source control
  • Contributes to BREEAM scoring
  • Improves quality of discharged storm water
  • Overall time and cost savings versus traditional methods
  • Often replaces the need to install underground attenuation tanks and the associated:

- Additional removal of excavated material required

- More transport and site traffic disruption

- A large carbon footprint


Important note about specifying:

  • The ABG blueroof system is compatible with hot melt or cold liquid applied waterproofing systems (specified separately)
  • For specific advice / SuDS attenuation project calculations during planning & design stages please contact ABG design department.
