Intensive green roofs.
Intensive sedum roofs.
Intensive green roofs have a growth layer of 110 to 120mm, which allows the growth of sedum herbs and sedum grasses, which develop roots. Therefore, a root-securing foil must be laid under the sedum planting, unless the roof membrane has inbuilt root-securing material. Plants on intensive green roofs should not be allowed to dry out.
The weight of the sedum herbs and grasses layer is approximately 130kg/m2, in its water-saturated state.
