Schule an der Insel Scharfenberg

A worker lays drainage plates. The sheets’ light-weight, waffled structure creates drainage and water storage space, while requiring lighter structural load requirements than a granular drainage.

A worker cuts drainage plates to fit around a roof penetration so that continuous drainage pathways exist everywhere on the roof.

Molly Meyer waters the fleece! Watering the separation layer after it is unrolled prevents wind uplift.

A crane lifts a supersack of growing media to the rooftop.

One worker controls the flow of the growing media from the supersack while the other distributes the material in a wheelbarrow. A thin layer of growing media was placed on the seams of the separation layer to prevent wind uplift and displacement by workers.

A bucket delivers washed river stone from the bed of a truck to the roof, where it is transported in a wheelbarrow to non-vegetated zones.

This roof has three vegetated sections. On the left, the growing media and washed river stone are distributed and leveled and their border is crisply defined. In the middle, the thin roof area has received growing media and washed river stone, but they are not leveled nor has their border been set. On the left, the growing media and washed river stone have yet to be installed.

Though the roof has not been planted in this photo, it is complete with vegetated and non-vegetated zones. Sedum cuttings were spread the following spring.
