Glass Reinforced Concrete (GRC)

Glass Reinforced Concrete (GRC) is an innovative composite material that combines a cement-based matrix with alkali-resistant glass fibres for enhanced strength and flexibility. Lightweight yet strong, GRC enables the creation of intricate shapes, thin panels, and elegant architectural forms that are difficult to achieve with conventional precast concrete. It offers excellent durability, weather resistance, and fire performance, making it an ideal choice for cladding, façades, screens, and decorative features in contemporary building design.

While Glass Reinforced Concrete offers many design advantages, it also comes with important considerations. GRC is not an orthotropic material, meaning its strength and stiffness are not uniform in all directions, which requires careful design and fibre orientation. It is also relatively brittle compared to other building materials. Additionally, GRC can experience a gradual loss of tensile strength which should be considered in the engineering design.

At STRUST, we understand the unique properties and potential of GRC in delivering both aesthetic and structural solutions. Our team works closely with architects, builders, and manufacturers to design, engineer, and detail GRC elements that meet the highest standards of quality and performance. We ensure careful consideration of fixings, tolerances, panel joints, and waterproofing details to achieve seamless integration with the building envelope while maintaining cost efficiency and constructability.

We provide engineering solutions for GRC panels across a wide range of applications in buildings, infrastructure, and civil projects. Our team supports architects, builders, and GRC manufacturers with design and detailing expertise based on deep knowledge in structural and façade engineering.

Our solutions include:

  • GRC with integrated GRC ribs

  • GRC with steel frames

  • GRC with aluminium frames

  • GRC integrated into curtain wall façades

  • GRC seating elements

  • GRC Planter boxes

  • GRC used as permanent formwork

  • GRC as Artificial Rock
