Shire Biodiversity Substrate
Substrate Description
Lightweight substrate made from coarse recycled brick and aircrete, composted bark and medium clay soil.
Substrate Application
General purpose green roof growing media for Biodiversity roofs
- Localised areas on biodiversity roofs to change vegetation
The Manufacturing Process
The manufacture of house bricks generates a significant percentage of bricks that do not meet the rigorous quality standards required for house building, for instance because of cracks or other damage and are scrapped. These cannot easily be reprocessed and they are set aside and crushed for use in other applications, e.g. as lightweight aggregates or for use as green roof growing media.
Green Compost
Where the Growing Media incorporates Compost it is derived from a sustainable source, normally 'pine bark' Compost.
Biodiversity Substrate used with meadow plants
