This system solution is suitable for pitched roofs with a slope of up to 15°, which usually do not require any constructive measures for shear protection. In order to still protect the roof from erosion and various problems such as slides that can occur during heavy rainfall events, a suitable system structure with erosion protection is sufficient. Sloping roof green roofs are designed as extensive green roofs as standard.
