Glass Reinforced Concrete (GRC) Lightweight Precast Alternative GRC panels can be provided with a standard grey concrete finish or a specially modified coloured concrete mix can be manufactured on the face of the GRC panels to enable the full range of normal precast finishes such as acid wash, sandblast or polished finish. Alternatively stone can be bonded to the face of GRC panels providing an economical and quick to install method of stone cladding to a building facade. GRC can be molded to any shape and can be attached to a light support frame on site or can come in full sized panels bonded to a steel frame ready to fix to the building structure.  Download the GRC Design Manual Download Here
