Solution

A combination of a lightweight organic growing medium for green roofs LiteTop from American Hydrotech and the Urbanscape Green Roll growing medium made of rock mineral wool fibres from Knauf Insulation has been used for the flat space. At the green-roof-to-green-wall transition this combination has been combined with the Ecose® Technology Green Wall Boards growing medium for green roofs made of rock mineral wool fibres. All growing media have been stabilized and strengthened with GardNet from Hydrotech.

To ensure a long-lasting success of these green swoops before they were installed, a test ‘ramp’ had been created and monitored for months.
