Typical Usage


GRC is one of the most popular materials used for creating prefabricated architectural cladding. GRC’s ability to be moulded into lightweight panels with variable thickness with a variety of shapes, forms and surface finishes has been appreciated by a growing audience of architects and engineers worldwide.

  • GRC is easily moulded to reproduce shapes, details and textures.
  • GRC is a high strength material that allows design of thin, lightweight cladding elements.
  • GRC can be coloured with pigments, paints and natural stone facings.
  • GRC cladding can replace non-structural precast concrete where weight and/or shape may be problematic.
  • GRC can be cast into fine details.
  • GRC offers designers unrivalled flexibility.
  • GRC mouldings and features are easy to handle and erect.
  • GRC does not suffer from corrosion.
  • GRC is an environment friendly Green Product.
  • GRC products reduce loadings on buildings leading to significant savings in superstructure and foundations.
  • GRC is excellent for reproduction and renovation.


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.
