BauderGREEN RE 40

Water attenuation and multi-directional drainage layer, used on roofs below five degree pitch. Made from 100% recycled high density polyethylene. Designed with a micro weep hole in the centre of each cell to give short term attenuation water storage for a green roof build up or as a drainage layer for hard landscaping. 

Used as a drainage layer and as a permanent shuttering for hard landscaping finishes (both permeable and non-permeable paving). It can be filled with sand/cement, gravel or Bauder Mineral Drain. 

Used as a drainage and attenuation layer when combined with Bauder ST-B adjustable flow restrictor and BauderGREEN SUB-RE Substrate within a green roof build-up. 

The profile of the RE 40 is similar to that of the DSE 40 drainage board and one can nest into the other if necessary. The micro weep hole is only present in the RE 40.
