Got any question?

Browse through our frequently asked questions to find answers on everything from mould preparation and casting techniques to finishing and long-term maintenance.

Australia’s warm and, in many regions, coastal climate necessitates adjustments during manufacturing. High temperatures can accelerate hydration, so controlled curing environments—such as covering pieces with plastic to retain moisture—are essential. Additionally, lower water-to-cement ratios and carefully selected admixtures help mitigate rapid evaporation and ensure that GFRC develops its designed strength and durability.

Manufacturers address these challenges by:

  • Using precision mixing equipment to achieve a uniform blend and ensure proper fibre distribution.
  • Fine-tuning spray parameters (such as pressure, nozzle design and technique) to avoid voids, pinholes and surface defects.
  • Regular maintenance of equipment and continuous operator training.
  • Adjusting admixture dosages as required to optimise workability and adhesion.

Future trends include increased automation—such as robotic spraying and digital mould design—as well as a greater focus on sustainable practices (e.g. incorporating recycled materials and eco-friendly admixtures). Advances in fibre treatment technology and computer-aided manufacturing are enabling more complex, custom-designed panels. Ongoing research is continually refining mix designs and curing methods to better suit Australia’s diverse environmental conditions.

GFRC is a composite product that combines high‐quality cement, fine aggregates, polymers and alkali‐resistant glass fibres – all premixed to the correct proportions. Its high strength‐to‐weight ratio, durability and capacity for being cast in thin, custom shapes make it ideal for creating stylish and long-lasting benches and tables for both indoor and outdoor use.

GFRC manufacturers must comply with Australian building codes and standards relating to precast concrete, structural performance and safety. This means that production processes, material testing and installation methods are stringently monitored and documented. Close collaboration with local certifying bodies ensures that GFRC products meet all necessary performance and regulatory requirements.

With our premix product, all the ingredients are already proportioned for optimal strength and workability. This means you can focus on preparing your moulds and executing a neat cast rather than measuring raw materials.

Moulds for benches and tables can be constructed from high-density foam, melamine, or even silicone for more intricate designs. It is essential that the mould is smooth, watertight and well supported. Pre-treat the interior with a quality release agent to ensure that the cured GFRC can be removed cleanly.

Typical additional admixtures levels for a 20kg:

  • Water: 2.78L–3.0L
  • Plasticiser: 10g – 50g
  • Fibres HD: 50g-300g
  • Fibres Bundled: 400g-700g
  • Retarder: 5g-20g
  • Accelerator: 5g–20g
