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 green waste compost to PAS 100, derived from horticultural wastes collected during municipal works, e.g. hedge trimming, etc.

"Shire provided me with authoritative advice on soil weights, depths and constituents for both my extensive and intensive roofs. They were able to provide local materials from the south east and they were able to deliver the 20 tonnes of soil on an articulated lorry with its own forklift. Everything from the first enquiry to the final delivery was carried out in a very professional way."
