Added green roof protection for former WWII bunker with Blackdown green roof and Derbigum waterproofing

Originally built as a decoy target for German WWII bombers, The Decoy Bunker in Monmouthshire has been restored as a unique holiday home. A highly durable green roof waterproofing system gives the former bunker the desired camouflage effect and provides full protection against water flowing down the hillside.

Alumasc’s registered contractor Span Roofing installed a Derbigum Black Anti-Root Built-Up System below the green roof to provide a reliable waterproofing solution, then Blackdown Greenroof Drainage Layers, Intensive Substrate and Washed Pebble Ballast.
