The Manufacturing Process

This substrate is a manufactured by combining a BS3882:2015 compliant loam topsoil made with PAS100 green waste compost blended with specially graded sustainable aggregates. In the case of this substrate it is lightweight expanded clay aggregate mixed with greensand aggregate and specially crushed aircrete sourced directly from the supplier of autoclaved blocks. Damaged or cracked blocks that cannot be supplied to house builders are set aside and crushed to our specification for use in green roof growing media.

BSI PAS 100 Green Waste 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.
