The Green Roof Biodiverse is commonly used where the vegetation is intended to replace or replicate the existing site habitat.
Sometimes referred to as roof gardens, an intensive green roof can be as simple or as complex as required. Generally, an intensive green roof requires the same level of care as any traditional garden. Intensive green roofs consist of a deep layer of engineered growing media, typically 150–1500 mm. As a result of this soil depth there is a greater scope of planting available and the roof 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. For large areas it is imperative that consideration is given to the provision of adequate sub-surface drainage.
Intensive green roofs have a deeper layer of growing medium than extensive roofs. This increased depth has a greater capacity to retain water making it less likely to dry out. Utilizing a drainage composite such as ABG Deckdrain, reduces the risk of over saturation of the plants during periods of heavy rainfall. The high strength core used in ABG Deckdrain allows the product to be used in high load areas such as on podium decks with vehicular traffic.
ABG Deckdrain consists of a combination of a cuspated core with a geotextile fleece bonded to the upper face. It is manufactured in the UK from up to 95% recycled material bonded to the upper face.
Green Roof Intensive comprises:
- Engineered growing media:
ABG peat free media derived from sustainable, recycled, UK sourced materials. Using a specifically developed growing media can help provide the right growing environment for the selected vegetation and also reduce the load on the roof.
- Vegetation/ Surfacing:
On Intensive green roofs a wide variety of vegetation can be used from grasses to shrubs and trees as well as hard surfacing such as pavers and block paving.
- Deckdrain:
Forms a lightweight high performance drainage layer with integrated filter geotextile that eliminates clogging within the drainage structure that provides a continuous drainage layer across the structure.
It provides excellent drainage over the whole base area of the soil layer as well as providing additional waterproofing protection. With more emphasis on reducing the amount of carbon used in construction, recycled materials can provide additional environmental benefits.
