They are not intended for general access or for leisure purposes and are primarily used for their ecological benefits or aesthetic appearance. There are two options available, offering differing substrate depths which are needed to support the desired planting scheme. Sedum blanket Lightest weight option available, with hardy, pre-cultivated sedum vegetation for instant greening of the roof.
