Introduced in 1969, glass reinforced cement (GRC) has become a useful material for the designers, architects and engineers. An environmentally friendly cementitious composite, GRC today is a strong lightweight material that can be moulded to many shapes and applications. We can track the development of GRC and it’s uses by following the history of BCM from the late 70’s as we have led the way in development of the application of GRC in agriculture, drainage, architecture, formwork and rail.
