Parklands on Rooftops and Underground Garage Decks

Frequently, green areas are installed on underground car park decks in conjunction with different types of pathways or vehicle surfaces. 

Due to the accessibility of underground car park decks and their normally generous structural load reserves, they provide a good opportunity for using a build-up where the substrate can be applied using a wheel loader. In the system build-up the Protectodrain® or Elastodrain® studded sheets that cover the entire area, protect the roof membrane from all types of dynamic forces, even during the building phase. Covered with the stable filter sheet TG or PV, they also allow for excess water to safely drain off.

Together with Zincolit® Plus and the System Substrates, the build-up offers the widest possible range of solutions for planting and design.
