Glassfibre reinforced concrete (GRC) is one of the most versatile building materials available to architects and engineers today.

GRC is a composite material comprising a mixture of hydraulic cement, silica sand, alkali resistant (AR) glass fibres and water. The glass fibres in GRC effectively reinforce the mortar mix, thereby improving its tensile strength and characteristics.

GRC is ideally suited for lightweight, prefabricated exterior cladding panels but is so versatile it can be moulded into almost any complex shape and profiles.

The main advantage of GRC panels over the corresponding precast concrete alternatives is the considerable saving in weight. Other notable advantages of GRC cladding are its seismic capabilities, durability, chemical resistance, non-combustibility and good sound/heat insulation properties.

Based in Henderson Auckland, GRC NZ welcomes visits from architects and designers by appointment. Regularly updated photos of projects in progress appear on GRC NZ’s facebook and web page (with a new website coming soon)
