MoBicast Ð multi-tasking WitH Precast concrete CMA producer member, Mobicast, has once again demonstrated its versatility in the production of diverse precast concrete products. 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.
