Posted by david.luukas

Alumasc is proud to announce that we have two sustainable and innovative green roof projects shortlisted at this year’s 2018 NFRC  (National Federation of Roofing Contractors) Awards, below we look back at the green roof projects…

Project One:

green roof system alumasc roofing systems

Tucked away in the rolling hillsides of Monmouthshire is The Decoy Bunker. The original bunker was built in 1941 and was designed as a special decoy target for German bombers.

NFRC Awards 2018

The secluded bunker has now been fully restored and is now a unique holiday home.

As part of the design, the bunker needed to blend directly into the hillside, therefore, a highly durable waterproofing system that could provide full protection from the water travelling down from the surrounding landscape was needed. A green roof waterproofing solution that would provide the maximum blending effect was also required to give it the desired ‘camouflage’ effect by using the existing soil and grass from the surrounding landscape. Blackdown Drainage Layers, Intensive Substrate and Washed Pebble Ballast was installed to finish the green roof.

With Derbigum being a system that holds 40-year durability certification with the BBA (British Board of Agrément) – a Derbigum Black Anti-Root Built-Up System was the ideal solution. The Derbigum system sits below the green roof and provides a highly reliable waterproofing solution and maximum peace of mind for the future. Alumasc’s Registered Contractors Span Roofing carried out the installation with great results.

Project Two:


Blackdown are proud to have completed the sedum green roof at the Chester Bus Interchange site which is a £10 million ‘key enabling’ project and part of the wider £300m Chester Northgate Redevelopment.

The bus interchange is capable of handling 156 bus movements per hour & opened in early 2017. Blackdown worked alongside Lakesmere, who installed the Kalzip roof and Graham Construction the main contractor.

The project has a 3,434sqm sedum green roof with a varied pitch from 0-35 degrees installed over a Kalzip standing seam roof.

Blackdown would like to thank both Graham Construction and Lakesmere for the positive and close working partnership throughout the duration of this exciting project.
