Glassfibre Reinforced Concrete (GRC) has been extensively used as permanent formwork for the past twenty years, corrugated or flat to suit all supporting beam design.
GRC formwork combines the well-established compressive properties of cement-based mortars with the valuable flexural and tensile properties contributed by the glass fibre to give a material with the following characteristics:
dense and crack resistant
non-combustible with excellent resistance to fire and surface spread of flamelow water, water vapour, and air permeability - contributing to low carbonation rates and resistance to both sulphate and chloride attack
good abrasion resistance
freedom from rot, corrosion, and UV degradation
easy to handle on - site, yet heavy enough to be stableminimum maintenance
