It is getting easier and cheaper to convert flat roofs and podium decks into attractive, useful, environmentally friendly green spaces. But it is Wallbarn’s innovative modular solution that has taken the greatest strides in overcoming some of the challenges historically associated with designing and installing green roofs.
Pre-grown to maturity The superior vegetation in Wallbarn’s M-Trays is pre-grown in specially-designed modules for approximately six months at their dedicated UK nursery. Wallbarn have developed its own specially-designed substrate mix which means there is considerable root growth already in the tray. This ensures that by the time they are delivered the plants are strong, established and provide consistent cover over the intended area.
The modules contain a carefully-selected mixture of flowering sedum varieties, providing year-round greening and also different textures and flowers throughout the summer. A species list can be downloaded via the link above.
The modules are highly portable and simply clip together, meaning they can be installed much faster than roll-out systems without any specialist landscaping or roofing knowledge. The M-Tray’s unique design means rainwater gets retained far longer and very little maintenance is required through the seasons.
Pallets should be unloaded immediately after receipt to prevent damage to plants by extended periods stacked up.
Prior to installation, a geotextile fleece should be laid under the trays to help prevent soil deposits entering the drainage system. Wallbarn supplies a recycled geotextile fleece for this purpose.
