BauderBLUE STORMcell

Creating a blue roof beneath a green roof finish for high volumes of stormwater attenuation.

The surface finish freely drains into the attenuating cavity forming layers that allow free-flowing movement of water to the flow restrictor outlets.

When to specify 

BauderBLUE STORMcell system creates a blue roof beneath a roof finish for high volumes of storm water attenuation. The surface finish freely drains into the attenuating cavity forming layers that allow free-flowing movement of water to the flow restrictor outlets.

This solution is designed to hold high volumes of stormwater during severe rain events and reduce the flow rate from the roof to acceptable levels for the drainage system.

The BauderGREEN RWR 100 creates the void space beneath the roof finish and can be used in a multi-layer solution for increased levels of water attenuation. The product is >95% void and achieves compressive strength ≥400kN/m2 for use under green roofs, roof mounted equipment, and hard landscaping surfaces.

​Plus points 

  • Accommodates high volumes of water
  • Suitable as a base to build soft and hard landscaping including planters and paving details.
  • BauderGREEN RWR 100 made from recycled plastic.
  • High levels of compressive strength, suitable to mount plant equipment.
  • Ideal as part of a comprehensive BREEAM solution.
  • Specify with our BauderSOLAR G LIGHT biosolar PV array.
  • Comprehensive range of guarantee packages to fulfil cover requirements for the project (dependant  on system/product selection). For more information contact our technical dept for a sample guarantee  outlining cover level, terms and conditions.
