M-Tray sedum green roofs from Wallbarn in the spring

Another great example of the simplicity and beauty of the M-Tray sedum green roof system on offer from Wallbarn, in conjunction with the SIG group.

A single storey extension in Cambridgeshire been had been waterproofed by AJ Canning and was overlaid with the sedum M-Tray pre-grown modules. Loose laid geotextile separation membrane was placed directly onto the waterproofing membrane and the M-Tray modules, which had been grown in the Wallbarn nurseries for over 12 months, were installed onto the geotextile and clicked together using the easy connection fittings.

The sedum was healthy, established and lush. Areas around the rooflights were filled with washed riverstones and the border areas were fitted with aluminium edging bars to give suitable separation, preventing roots and leaves invading drainage outlets.

M-Trays are the fasted, cleanest and simple way to construct green roofs. They are available in a 2-3 day service. They are delivered on pallets, which can be craned directly onto the roof. If access is an issue, they modules can be unpacked and carried individually onto it.
