Wallbarn won a contract to provide a major nursery stock grower in British Columbia with a very large sedum green roof project on a tower block in Vancouver.
The architect was concerned about future-proofing the green roof and wanted to ensure that, if ever they had issues with their waterproofing seal or any other aspect of the structure, the green roof could be taken up without too much disruption. It was decided that a modular solution would be the best route.
M-Tray® was included in a worldwide competition to find the most suitable modular design and was judged as the best product available.
Wallbarn supplied the empty M-Tray® units to the grower, who installed them empty on the roof and blew the substrate via a suction machine onto the roof from the ground. Sedum plug plants which had been grown in the client’s greenhouses were hand planted into the modules at a rate of 8-10 plants per m2.
The whole area was irrigated and fertilized regularly for the first few months until the plants spread to cover the whole area with thick vegetation
