BauderGREEN DSE 20 is a HDPE water storage and multi-directional drainage layer. It is suitable on roofs below 5° pitch. 

Installed over the completed waterproofing, this layer provides continuous drainage for both hard and soft landscaping. It is primarily used in areas with moderate loads, such as extensive green roofs, beneath paving set on sand/cement or gravel bedding, and within planter beds.
