The southern Cape producer recently completed two very different fasttrack projects simultaneously. These involved the casting of the 300 concrete weight collars for Mossel Bay’s new desalination plant and supplying 7 000m² of concrete block paving (CBP) for the parking lot of the newly extended knysna Mall.
