Long Rake Spar have developed three categories of Green Roof substrates each containing a blend to specific proportions of recycled and lightweight aggregates with composted bio waste products. The three products have been designed to suit most landscaping and ecological specifications:
Intensive System Substrates (ISS): An ultra lightweight blend of highly absorbent aggregates with composted bio-waste to be used as a substrate within recreational garden-scapes.
Extensive System Substrates (ESS): A blend of lightweight, water absorbent aggregates with composted bio-waste to be used as a substrate in un-maintained rooftop environments.
Mineral Drain Aggregate (MDA): A free draining, angular, lightweight aggregate for use as a drainage layer below the substrate to prevent slipping on sloping roofs with Extensive systems.
Brown Roofing Substrates (BRS): A blend of reclaimed aggregates with composted bio-waste designed to promote regeneration of the bio-diversity of demolition sites which have been lost to construction.
