The Urbanscape® QuickBox is installed over the outlets on extensive green roofs as part of the Urbanscape® Green Roof System. According to FLL Guideline drainage outlets have to be accesible all the time. The Urbanscape® QuickBox allows the inspection and maintenance of drainage outlets. The box consists of a high-quality polypropylene base with weight distribution footprints and a lockable lid with openings to secure the drainage of overflow from the green roof build-up as well as surface water from the vegetation layer.
