GRC products are formed by a variety of manufacturing techniques. One of the most versatile techniques is to cast the composite in moulds manufactured from rubber, timber or Glass Fibre Reinforced Plastic (GFRP/GRP). This is known as Premix GRC. As the high-performance alkali resistant glass fibres are evenly distributed in the mix, the material is reinforced throughout, enabling products with the finest of details to be created.
GRC is used to produce beautiful architectural mouldings and features. Whilst often cast with thicknesses in excess of 25mm these products remain easy to handle and erect and permit the architect or engineer an unrivalled freedom for creative design. GRC does not suffer from corrosion of the reinforcement. Unlike traditional concrete, GRC does not require a minimum of concrete cover to the reinforcement.
GRC cladding panels are generally manufactured by the “Hand Spray’ technique. As the name implies, the material is sprayed into a mould using special machinery. The method can produce high-performance materials from which panels with extremely thin, lightweight sections are achievable.
GRC presents architects and engineers with a material from which the most ambitious designs can be created. It can be moulded to form modern futuristic designs or to replicate traditional historic features. GRC can be painted, faced with fine aggregates, coloured or simply left with a natural white or grey, smooth or textured finish.
