Blackdown Intensive Green Roof

Key Features & Applications

• Blackdown Intensive green roofs replicate ground based landscaping for recreational use and are generally installed on new build schemes with roof and podium decks.
• They usually consist of a mixture of hard and soft landscaping with lawns, water features, large shrubs and semi-mature trees all possible. 
• As well as providing recreational space and a rich habitat for wildlife, intensive green roofs reduce water run-off. 
• Blackdown green roofs comply with the UK’s GRO Green Roof Code of Best Practice 2011 and the German Landscaping and Landscape Development Research Facility (FLL) Guidelines.

Design, Planting & Waterproofing

• Blackdown intensive green roofs have a typical substrate depth that ranges from 200-1500mm and require a permanent irrigation system and regular maintenance.
• Blackdown intensive substrate is required; the substrate contains more organic matter than other green roof types, and is designed to support a wider variety of plants and trees.
• Planting can include lawns, shrubs, edible plants, perennials and grasses, small deciduous trees and conifers. Planting type and size determines required irrigation system and soil depth.
• Waterproofing options include Hydrotech hot-melt structural waterproofing, Derbigum high performance membranes and Euroroof Mastergold membranes.

Installation & Maintenance

• Blackdown green roofs can be installed by Alumasc's nationwide network of Registered Contractors
• Blackdown intensive green roofs are designed to accommodate the imposed loads of a full roof garden and require regular irrigation, personnel access and regular maintenance. The maintenance regime depends on the plant species installed.
• Warranties are available for the Alumasc waterproofing system used in the green roof build up.
