Glass-fibre reinforced concrete (GRC) is a lightweight yet high-strength material made from cement, water, polymer additive and glass fibres.
It offers unmatched design versatility, from hyper-modern shapes to timeless classical aesthetics, making it an ideal choice for any architectural vision. With its thin, custom profiles and resource-efficient production, GRC supports sustainability-focused construction projects by minimising material use and offering a durable, long-lasting solution for contemporary architecture.

While ordinary concrete is often reinforced with steel and used widely in load-bearing structures, GRC is reinforced with glass fibres for superior bending and tensile strength. This unique composition allows for thinner, lighter elements — often as thin as 12 mm — which are easier to transport and install.
Unlike conventional concrete, GRC is not used for load-bearing structures, but it excels in design versatility, supporting complex geometries and creative freedom that standard concrete cannot achieve. It is ideal for a wide range of applications, including façade cladding, balconies and ornaments.

No, both terms describe the same material.
GRC is the British abbreviation of „glass-fibre reinforced concrete“, while GFRC is its American counterpart, „glass-fibre reinforced concrete“. We use the term GRC because it matches our British and Danish roots.
Yes — thanks to our manufacturing methods, our GRC carries an A1 fire classification according to EN 13501-1:2018. That makes our GRC a non-combustible material suitable for fire-rated projects.
However, not all GRC is created equal — so even though our GRC has an A1 fire rating, the same may not be true for other manufacturers.

Absolutely. GRC offers unmatched design freedom for both simple and complex forms. Using custom moulds and advanced spray techniques, we can produce elements tailored to your specifications. You can also choose unique textures, patterns or even combine methods such as CNC milling and aggregate exposure for a custom finish.
For inspiration, see how GRC has been used in our past projects.
Our GRC elements can be coloured during the casting process using non-toxic iron oxides, offering a broad palette of cement-based tones inspired by RAL or NCS. For brighter finishes we offer our own silicate-based colouring service to achieve the look you want.
Your project's colour palette can blend harmoniously with nature, create striking contrasts or even sparkling effects through custom aggregates.

No significant maintenance is required.
After installation no technical maintenance is needed, and if cleaning is required the façade can simply be washed to look like new again. The low maintenance demand helps reduce life-cycle and operational costs.

Few materials are truly „sustainable“, but GRC offers properties that make it a strong choice for sustainability-focused projects.
Its lightweight design reduces transport emissions, while its durability and long service life keep resource consumption low over time.
GRC contains no toxic substances, is highly resistant to weathering and wear, and can potentially be reused in renovations — supporting circular construction practices. Made with minimal waste, it integrates smoothly into projects aiming for a low CO2 footprint or environmental certifications such as LEED, DGNB or BREEAM.
Yes. GRC supports sustainability-driven construction through its lightweight design — reducing transport emissions and structural loads. Its durability minimises resource use and life-cycle costs. In addition, GRC production excludes toxic substances and elements can be reused during renovation, further aligning with sustainable construction practice.
GRC elements are built for a service life of at least 50 years, with a design life expectation of more than 100 years for the concrete itself, with no need for maintenance. GRC is particularly weather-resistant, and unlike materials such as wood or metal, GRC does not rot, rust, crack or burn — making it an ideal choice for long-term projects with minimal life-cycle costs.
Yes — GRC is exceptionally weather-resistant. Whether under frost, intense heat, heavy rain or high winds, GRC maintains its integrity, providing a strong and durable building envelope.
Yes. GRC's lightweight, slim profiles make transport and installation simpler. We also offer integration with concealed mounting systems, eliminating visible screws and reducing the need for on-site adjustment. Our elements are made to order, ensuring seamless integration into your project.
GRC pairs well with other materials such as wood and metal thanks to its lightweight properties and versatile design. It is even compatible with load-bearing wooden structures, offering flexibility for hybrid construction projects.
