Added Green Roof protection for former WWII bunker

Originally built in 1941 as a special decoy target for German bombers, The Decoy Bunker is tucked away in the rolling hillsides of Monmouthshire and has been fully restored as a unique holiday home.

As the bunker had to blend directly into the hillside, a highly durable waterproofing system was needed to provide full protection against water travelling down from the surrounding landscape: a green roof waterproofing solution that would provide the desired ‘camouflage’ effect by using the existing soil and grass from the surrounding landscape.

Alumasc’s Registered Contractors Span Roofing installed Blackdown Greenroof Drainage Layers, Intensive Substrate and Washed Pebble Ballast to finish the green roof. A Derbigum Black Anti-Root Built-Up System sits below the green roof and provides a highly reliable waterproofing solution and maximum peace of mind for the future, as the Derbigum system holds 40-year durability certification with the BBA (British Board of Agrément).
