Retention under Green Roofs

RE 50B, RE 80B and RE 120B - The Blue Solution

Our Systems RE 50B, RE 80B and RE 120B are suitable for a sustainable retention of excess water under green roofs

Plants: Sedum, modest perennials

Growing medium: Extensive substrate Hydrotex-E, application height 8 cm

Separation layer: Quality fleece PP 150 g/m², GRK 3

Retention-element: RE 50B* / RE 80B / RE 120B* (*not shown)

Protection layer: Standard fleece PES/PP 800 g/m²

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 extensive 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 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.
