Intensive Green Roofs, often referred to as ‘Roof Gardens’, can be viewed very much like a garden area and may be landscaped to include trees, lawns, flower beds and paved areas. With an intensive roof the only real limit to its scope is the weight of the system and the structure necessary to support it. Many modern developments incorporate landscaped roofs at ground level, for example above basement areas and underground car parks. These are commonly referred to as podium decks. The decked areas themselves create additional usable space in urban developments.

Intensive Green Roofs typically consists of a drainage & reservoir layer under soft landscaping; Roofdrain, and a drainage only layer beneath hard landscaped areas; Deckdrain. Thereafter an Intensive growing media is applied in soft landscaped locations prior to planting.
