Delta’s Concrete Recycling Division provides a cost effective and sustainable alternate for construction and demolition waste disposal. This waste stream is a valuable resource for the recycling industry and its end products provide an excellent virgin quarry material substitute for use in all construction applications with a significant density advantage. (Images of raw feed attached – Raw Concrete, Raw Brick and Raw Excavation Rock)

Predominantly consisting of reinforced concrete, concrete washout, brick rubble and excavation rock, these waste resources are effectively reprocessed with contaminants removed to produce high quality specification construction materials. Smaller volumes of asphalt, glass and clay are also utilised within the finished products where applicable. Products are accredited and achieve VicRoads, RTA and Main Roads specifications and with <1% (by volume) deleterious constituents. 

All Delta sites operate under approved conditions which maintain the highest level of quality control for incoming material, reprocessing and finished product sales. On site NATA accredited laboratories’ test all products to Australian Standards and contaminants including asbestos are independently tested.
