13mm alkali‑resistant GFRC glass fibres designed for professional Glass Fibre Reinforced Concrete projects, delivering stronger, lighter and more formable concrete mixes.

  • Size and form: 13mm strand glass fibres tailored for GFRC applications to integrate smoothly into cementitious mixes.
  • Material: Alkali-resistant glass fibres, engineered to withstand the alkaline environment of concrete.
  • Weight and thickness impact: Can help reduce finished piece weight by up to 75% and enable thinner cast sections compared with solid wet cast concrete.
  • Workability: Contributes to a mix that is easier to work with and form, supporting consistent, repeatable results.
  • Dosage guidance: Recommended addition of 3% of the total mix weight in fibres for optimal performance.
  • Packaging: Sold by the kilogram for precise budgeting and scalable production.
  • Safety and compliance: Safety Data Sheet available for download to support safe handling and compliance.
  • Ideal applications: Suitable for GFRC countertops, architectural panels, thin cladding and other lightweight, high‑performance components.

This fibre reinforcement supports professional GFRC production by enhancing strength while keeping components lightweight and workable. The alkali-resistant formulation ensures durability in concrete environments, allowing designers to push thin profiles and intricate forms without compromising performance. With a clear 3% dosage guideline and kilogram‑level packaging, it’s straightforward to plan, mix and scale for both small batches and larger runs. Practical use includes evenly distributing fibres to avoid clumping and achieving consistent properties across moulds and sections, making it a reliable choice for architectural GFRC elements and decorative pieces.
