Further Detailed Information
In order to help make your selection of our green roof system as simple as possible you will find all the relevant documentation needed for your specification and designs below.
Driven by planning and local authority targets and the clients or end users requirements as well as stormwater retention, amenity, health and social cohesion goals.
They usually consist of a mixture of hard and soft landscaping with lawns, water features, large shrubs and semi-mature trees.
Intensive green roof build-ups over roofs & podiums are designed to be trafficked and should only be installed on flat roofs.
Design, Planting and Waterproofing
The buildup heights and weights will be very dependent upon the type of planting specified, however, as a rough guide 300 to 1500mm are the typical depths and weights could be in the region of 400kg to over a tonne per sqm.
Due to the increased depth of substrate; intensive planting can be similar to ground-based planting; lawns, shrubs, planters and trees. However, due consideration needs to be given to the adequate provision of irrigation, orientation, aspect and exposure to ensure the best results from the planting chosen.

Installation and Maintenance
Blackdown green roofs can be installed by the Blackdown in-house Contracts Division or by Alumasc's nationwide network of Registered Contractors
Intensive green roofs have higher maintenance requirements than extensive or a semi-intensive roofs. These maintenance tasks would be similar to those required for any ground based hard or soft landscaping elements.
Permanent irrigation systems incorporated into the scheme will also have maintenance schedules.
