Construction Photographs
 

Figure 1: The roof before construction (8 years old).

Figure 2a: The roof was tarred and resealed with a rubber lining.

Figure 2b: Extending the life of the underlying roof as well as the life of the green roof.

Figure 3: The insulation mat was then put down over the refurbished roof.

Figure 4: The black "egg crate" layer is the drainage layer but also allows for additional water retention in dry periods for the plants.

Figure 5: The filter fabric keeps the growth media (small, soil-like minerals) and drainage layer separate.

Figure 6: Using a crane, the growth media is delivered to the roof in large bags.

Figure 7: The media is spread evenly over the filter fabric and underlying layers.

Figure 8a: Plugs of various Sedum plants are taken from their trays.

Figure 8b: Plugs are evenly distributed throughout the media and are watered.
