Blue Roof Drain

Unlike active systems which inhibit water flow through drainage pipes passive systems temporarily detain water on the surface of the roof by lengthening the path the water must take in order to reach outlet drains.

Blue roof drain.

Cavidrain building abg cavidrain drainage geocomposite is a preformed cavity drainage system designed to relieve water penetration from basements and buried structures. Check dams installed to pond sheet flow to roof drains. Blue roof systems are an effective practice for controlling runoff from buildings with flat or mildly sloped roof surfaces. The patented blue roof system utilises the roof construction for the attenuation of stormwater releasing it at a controlled rate in the period following the storm.

The suitability of a blue roof and potential design options for a given building are determined based on various factors including structural capacity roof type and slope local climate and local regulatory requirements. A bauderblue roof is designed specifically for each individual project. 4 6 1 blue roof introduction. Passive blue roof systems control the rate at which water drains from a rooftop through non mechanical means.

Instead of forcing rainwater to flow directly into an underground drainage system surface water is collected and stored and if necessary cleaned before it is used or released back into. For example the ontario building code o reg. The bauderblue roof system is a sustainable drainage method designed to attenuate and manage stormwater on a flat roof over a 24 hour period via a restrictive flow outlet.
