blueroof - Geosynthetics

blueroof offers a new concept in the management of storm water. Changing weather patterns means rainfall events have become more extreme challenging the way water is managed. blueroof utilises the roof construction for the attenuation of storm water releasing it at a controlled rate in the period following the storm. Traditional drainage methods have allowed rain water to simply run off the building and into storm water sewers or natural water courses, this lack of management is a major factor in the rising number of flood events occurring throughout the country.


The adoption of SuDS within legislation forces designers to pay more attention to how the rain water is managed. There are many techniques available but the provision of attenuation within the site remains a central tenet in the design. Many projects have utilised a underground storage unit, usually constructed using a proprietary box system but these are not always cost effective, often require extensive civil engineering works and take up valuable land space, not always available particularly on inner city developments.


blueroof offers a radical rethink in roof drainage; the emphasis is switched to utilising the space to provide attenuation capacity rather than quickly moving the water elsewhere. Water attenuated within the roof area can then be release at a controlled rate through a bespoke restrictor outlet designed specifically to offer variable discharge rates and keep the flow off the site within the levels set by the local authority as part of the discharge consent.

ABG'S blueroof system can be incoprorated in to a landscaped podium area, a green roof construction or as a stand alone system on a traditional ballasted roof.
