-20mm Recycled Blended Base

Demolished concrete, brick, roof tiles, ceramic tiles, road base and asphalt are a valuable resource material that can be suitably recycled and blended back into various construction materials. Using recycled Construction & Demolition materials in your next construction project eliminates the need for demolished C & D waste being disposed of at council land fill sites, which assists in protecting the environment from further degradation.
