As well on extensive as on intensive green roofs drainage and water storage elements care on the one hand for a sufficient supply of water for the plants. On the other hand they do also care for the discharge of excess water. 6 fürs Grün offers a wide range of drainage and water storage boards:

WE 25 - The pressure -resistant Solution
WE 25 - The pressure -resistant solution - is the ideal alternative to the simple sedum green roof. In this case low-maintenance perennials of our plant assortment type "Pink" can be planted and next to them paths or patios can be constructed.

WE 25 - The pressure-resistant solution - is on the one hand a stable underground for flagging on green roofs. On the other hand it is a drainage and water storage board for sedum and perennials.

The water retention element WE 25 reduces due to its discharge delay effect the top discharge coefficients of extreme rain and discharges the public sewerage system thus it redounds to flood prevention.

WE 40 – The water-storing Solution
With the drainage and water storage element WE 40 – The water-storing solution - you can build intensive green roofs with a combination of perennials and bushes.
With a water storage capacity of 19.59 litre of water per square meter it guarantees a considerable rain water retention and it secures in a high demand the provision of the plants.

The high impact and pressure resistant raw material (HIPS) ensures the accessibility of the boards also under flagging, so that WE 40 can also be used as drainage board under walkable circulation areas. A real all-rounder!

WE 60 and WE 60 UG – The multi-purpose Solution
The drainage and water storage board WE 60 - The multi-purpose solution - is ideal for versatile intensive green roofs. You can let your imagination run wild.  Thanks to the extremely high water-storage-capacity of 30.5 l/m² of the drainage and water storage board WE 60 you can combine trees, shrubs and perennials. 

The drainage element WE 60 UG is slotted on the bottom. It enables you to combine the green areas of your roof garden with paths, patios, parking places or fire lanes. 

WE 60 and WE 60 UG - together they are an unbeatable team as they can also be used as a 120 mm retention-element.
