Our Systems RE 50B, RE 80B and RE 120B are suitable for a sustainable retention of excess water under green roofs
With RE 50B, RE 80B and RE 120B – The Blue Solution – in combination with a dam-up element a large rainwater retention volume can be created under green roofs with accessible areas on green roofs. In case of heavy rain such a retention roof significantly relieves the public sewerage system.
The large boards of RE 50B, 80B and 120B – The Blue Solution - ensure a quick installation. They are placed on top of each other. The dimples interlock precisely and guarantee for a secure connection without time-consuming attachment of connectors. Thanks to the blue control line on the boards, the correct installation can be checked immediately.
