Recycled Aggregates | Heard Group

The process in which we produce our recycled aggregates is called "Dry Screening" – this process involves the raw material that comes in to our recycling centres (concrete, hardcore, tarmac, hoggin, as dug ballast etc) being crushed at a specific size and screened using our 5 way split. Each of the 5 arms produces a separate aggregate.
