Considerations for a rooftop sustainable urban drainage system (SuDS) in flood-sensitive areas.

A BauderBLUE roof is a solution for urban areas where options for ground-based attenuation systems are limited and where construction is being carried out within flood-sensitive areas.

This presentation examines:
  • The key aspects to meet the planning conditions for limiting water egress from a site.
  • Current legislation, British Standards and codes of practice. 
  • The design of a blue roof.
  • Drainage mechanism.
  • Construction of the roof deck.
  • Suitable waterproofing.
  • Outlets and buildup components.
  • Detailing.
  • Options for the final visual finish. 

On completion

You will understand how a rooftop SuDS delivers water attenuation over a 24hr period to manage stormwater and how to design a successful blue roof.
