Definition
Glass-fibre reinforced concrete is a light cement mix reinforced with glass fibres and cast in moulds to make decorative facade elements such as arches, cornices and screens.
Why it matters on a project
It gives complex shapes at much less weight than stone or ordinary concrete, but fixing it needs proper details and joint sealing.
Measurement and pricing
Measured in square metres, linear metres or per piece depending on the shape.
Common mistake
Fixing panels without a designed steel frame, or leaving joints unsealed, so water gets in and panels crack.
Frequently asked questions
What is the difference between GRC and GRG?
GRC is cement-based and weather-resistant for exteriors; GRG is gypsum-based for interior ceilings and features.
Does GRC withstand sun and humidity?
Yes, if made with the right mix, fixed on a suitable frame and its joints are sealed.
