Extensive Green Roof System: Veg Tech Sedumbakker med biokul

Veg Tech Sedumbakker is an extensive green roof system that is lightweight, has high water retention capacity and is easy to install.

The product consists of a pre-planted tray with built-in drainage and water reservoir. The tray is filled with a mineral growth media (substrate) that forms the plant bed and is optimized for the conditions prevailing on roofs. The use of biochar in the substrate entails soil-improving properties that are especially important for greenery in urban environments. Biochar is also a potential carbon sink. The vegetation consists of drought-resistant species from the Crassulaceae family adapted to the Nordic climate. The sedum trays are cultivated in open fields in Denmark.

Veg Tech Sedumbakker are installed directly on top of the waterproofing membrane that is a part of the underlying roof construction.
