Biodiverse Green Roof with Deckdrain 20mm Drainage Board

Utilising 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.
