In every neighborhood where blue-green roofs were constructed, the local residents were inspired and kept well-informed about these smart roof projects.

Different types of vegetation can grow on the roof. Possible types are: moss, sedum, herbs, grasses, ferns, shrubs or a combination. There is a difference between extensive (sedum) and intensive (planting) green roofs.
The planting is rooted in the substrate layer, similar to soil. This layer provides support and nutrition to the plants.
The filter layer prevents particles from the substrate from ending up in the water storage layer and clogging it up. It also ensures an even distribution of the water that can be absorbed by the plants.
The water retention is an extra drainage layer. This layer consists of a lightweight crate system in which rainwater is stored. Here, an integrated fibre technology has been incorporated, which makes water transportation from the storage to the plants possible.
This layer protects the underlying roof construction from invading plant roots and it prevents leaks.

Root-resistant means that seeds from bird droppings that could grow into roots cannot take root on the RESILIO roof.

This ensures that the water remains on the roof.

This layer consists of small cement blocks with granules, which act as an insulating layer.

The bitumen layer that is already on the roof.

By means of this “smart valve” the stored rainwater can be discharged or retained in the drainage layer. This smart valve responds to weather change and opens and closes automatically at the right times.

The roof system, also called roof construction, bears the weight of the roof and provides thermal insulation.
