What is the Polder Roof®?
To make smart water storage on flat roofs technically possible, we were the first in the world to develop the Polde Roof concept. The Polder Roof makes an urban surface into a smart water storage layer. The water storage is controlled. In this way the system is able to store all rain that falls on the roof and to dispose of or use it at a quiet time. The Polder Roof serves as the basis for a green roof, roof garden or roof park. In addition, the water that is stored can be used for irrigation, infiltration or a greywater system.
How does the Polder Roof® work?
The installation consists of a buffer system base, and the Smart Flow Control . It is provided with a dike, possibly supplemented with a complete water separating layer. The Smart Flow Control measures and controls the water level as well as the run-off. Information about the roof and the operating system can be accessed via your personal dashboard.
The team behind this innovation ensures that all roofs are continuously in operation and manually update when necessary. The Polder Roof is truly a new layer in urban water management.
