Detail:
The project started by removing the existing roofing to install the necessary vapor barrier, insulation, and first layer of Famos waterproofing. The top membrane integrated copper foil into the modified membrane and surfaced with hydrogel crystals to improve drought resistance. Five inches of growth media topped the waterproofing. Over 1200 plants from 15 different species were installed on this roof. The landscape architect and plant supplier chose to use plants indigenous to Middle Tennessee. The edges and penetrations required an 18" border of pea gravel to aid in proper drainage and to limit root migration.
