GRC vs Precast Concrete vs Traditional Concrete: What Specifiers Need to Know
GRC vs Precast Concrete vs Traditional Concrete: What Specifiers Need to Know If you’re comparing facade cladding systems for a new build or refurbishment project, there’s a good chance GRC (glass reinforced concrete), precast concrete and traditional in-situ concrete are all sitting somewhere on your shortlist. They look superficially similar, they’re all cement-based, and they’re […]
Self-Cleaning GRC Facade Panels: The Science, Technology and Future of eGRC
Self-Cleaning GRC Facade Panels: The Science, Technology and Future of eGRC Urban buildings fight a constant, slow-motion battle against pollution. Diesel particulates, nitrogen oxides, volatile organic compounds and oily atmospheric aerosols adhere chemically to façade surfaces, forming a progressively thickening film that stains, degrades and ultimately disfigures even the most carefully detailed building envelope. For […]
GRC Moulds: A Complete Technical Guide to Materials, Design and Best Practice
The quality of any GRC element is inseparable from the quality of the mould used to make it. Unlike ordinary precast concrete — where formwork is a relatively crude, load-bearing container — a GRC mould is a precision engineering artefact. It must faithfully reproduce surface texture down to sub-millimetre detail, maintain tight dimensional tolerances through […]
GRC Fire Rating & Fire Classification-A1
When specifying façade cladding for buildings above 11 metres — or any project subject to the UK Building Regulations Part B — fire performance is non-negotiable. Glass Reinforced Concrete (GRC), also known as GFRC (Glass Fibre Reinforced Concrete), achieves Euroclass A1 — the highest possible reaction-to-fire classification under EN 13501-1:2007+A1:2009. This makes GRC cladding panels one of the […]
What Is GRC? A Complete Technical Guide to Glassfibre Reinforced Concrete
GRC – glassfibre reinforced concrete or sometimes just shortened to glass reinforced concrete – is one of the most technically sophisticated materials used in modern construction, yet it remains misunderstood by a large portion of the industry. If you are an architect, structural engineer, specifier, or contractor who has heard the term but isn’t quite […]
AR Glass Fibre in GRC: Why Alkali-Resistant Fibres Make or Break Long-Term Cladding Performance
Alkali-Resistant Glass Fibres: Why AR Glass Makes or Breaks GRC Walk up to almost any major architectural façade built with glass fibre reinforced concrete in the last 40 years and you’re looking at a material that, on the inside, is quietly engaged in a slow chemical battle. The cement matrix that gives GRC its compressive […]
