Description

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:

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

- Removal of excavated material required

- Transport and site traffic disruption

- Additional 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
  • Can be used for maintenance & amenity access areas
  • Loadings to be verified with ABG & the structural engineer with a minimum 250mm load bearing finish required for emergency vehicles.
