GRC (glass reinforced concrete) board is a fibre reinforced pre-cast concrete with a 50-50 sand cement matrix in a typical wall thickness of 12 to 15mm thick. Hollow rib profiles created around the perimeter and across the rear face at designed centres. provide the structural integrity of the components. These ribs are between 50 and 100mm in depth and are not visible once the façade is assembled.It is a technology proven in use over 25 years and GRC provides the designer with options for façade design that few other materials can match for versatility.
GRC or GFRC is made in thin concrete sections created by a proprietary process of machine spraying an enriched OP cement and aggregate mix within which alkali resistant glass fibres provide the reinforcement. Unlike steel, glass fibres will never rust and are placed throughout the thickness of the panels.
