Description

The IKO blue roof system provides an intelligent solution to incorporate attenuation capacity into green roofs or podium deck constructions. This supports sustainable urban development without the need for space-consuming ponds, retention basins, or huge underground storage tanks. The blue roof design combines a unified drainage and attenuation space within the roof structure, complemented by a roof outlet system aligned with site-specific planning consent.


This design empowers developers to achieve storage capacities with the ability to handle up to a one-in-a-hundred-year storm event, in addition to providing support for climate change allowance without compromising the aesthetic and functional qualities of the development. The stored water can be released at a controlled rate or used for greywater or irrigation purposes.


The geocomposite drainage system is a comprehensive and cost-effective solution to meet your storm-water attenuation requirements in roof construction. The system’s filtered geotextiles and restrictor chambers provide a controlled dispersal of excess water from the roof surface and discharge through the roof outlet, following the site-specific regulations.


The system offers numerous benefits, including reduced site disruption and excavation costs and storage within the building’s footprint—a massive advantage in densely urbanised areas.


The restrictor chamber provides controlled discharge, making our system a reliable and affordable solution to manage your storm-water attenuation needs.


Features and benefits:

Blue roofs help meet SuDS objectives by:

  • Controlling run-off ‘at source’.
  • Providing storage volume.
  • Improving water quality.
  • Providing source control within the footprint.
  • Valid part of the SuDS hierarchy and process chain.
  • Contributes to the environmental credentials of the development.
  • Installation issues reduced.
  • Potential to reduce the number of roof penetrations and RWOs.
  • Zero falls system.
  • Waste to landfill reduced.
  • Speed of site program improved.
  • Quality of discharged water improved.
  • Overall reduction in expected project costs.


During the design process, IKO, in collaboration with supply chain partners, will develop calculations to model the roof’s behaviour during storm events. This modelling takes into account essential factors such as:

  • Required discharge rates.
  • Attenuation volume requirements.
  • Time needed to complete discharge of attenuated water from the roof structure.
  • Roof type.
  • Design capacity.
  • Structural considerations.
  • Outlet design.
  • Thermal performance.
  • Waterproofing design.
  • Water quality.
  • Access and maintenance.
