Case Studies

Radisson Blu Hotel, Heathrow

M-Tray® Green roof

Overview

This project involved the greening of an existing bitumen rooftop overlooked by hotel rooms.

Access to the roof was through a busy working hotel which could have been an issue were it not for the highly portable shape of our specially-designed M-Trays®. They are easily transported to site by pallet and can then be stacked neatly onto a parcel trolley. Each M-Tray® unit is self-contained and needs no additional aggregate which means zero disruption, zero mess.

About the project

The M-Trays® were taken up onto the roof itself using a mini genie lift and slotted into position in a matter of hours. They were then dressed around the edges with gravel. 

Installation was fast and effective, taking only a day.

Alternative green roof solutions take a long time to establish themselves. For example a roll-out green roof can take many months just to recover from the shock of being installed.

Whereas Wallbarn’s M-Trays®, having mature, established root systems, are bedded-in within four months of installation and begin to flower with stunning results.

Ultimately, installing Wallbarn’s M-Trays® system allowed the hotel to convert an unsightly bitumen rooftop into a green and vibrant sky garden for guests to enjoy from their bedrooms.
