Sedum Roofs with Natural Drainage
Soil System Overview
Soil System Specifications
Technical DrawingsSedum roofs are extensive green roofs that have a media depth of 3-8 inches. There are two variations for the system build-up. Sedum roofs with a natural drainage layer are designed to maximize water retention, while sedum roofs with a synthetic drainage layer may focus more on minimizing weight. Low weight can be crucial for huge building structures and retrofit projects with limited roof loads. Sedum roofs have a great cost-to-benefit ratio and significant stormwater retention. Depending on the depth of the growth media these systems support Sedum and other succulents, as well as some hardy perennials and grasses which can be used to increase diversity or to adjust to regional conditions.
