BauderGREEN SUB-RE UK

Green and Blue roofs

This expanded clay aggregate has been developed as a substrate/growing medium, to be used as part of the BauderBLUE STORMsub roof system. The single grade particles are used with other Bauder drainage products to provide a Sustainable urban Drainage Systems (SuDS) solution at roof level. The substrate does not contain any free silica or other known hazardous substances. 

The SUB-RE UK substrate is typically used below a Bauder green roof build up. The SUB-RE UK substrate provides an additional depth of substrate for the vegetation in the green roof systems. The substrate’s large void ratio allows high levels of water storage making it a suitable blue roof void layer. 

Additionally, it provides aeration with inherent water retention to help support green roof plants. Typically used with the Bauder RE 40 drainage board.
