    PCE superplasticisers are transforming modern GRC production by improving workability while maintaining a low water-to-cement ratio. By enabling self-compacting GRC, Polycarboxylate Ether (PCE) technology helps manufacturers eliminate mechanical vibration, achieve superior surface finishes, reduce labour requirements, and produce complex architectural components with greater efficiency and consistency.

    FRP rebar is increasingly being adopted across a wide range of construction sectors due to its corrosion resistance, durability, and long-term performance benefits. Whilst often associated with bridge infrastructure, Fibre Reinforced Polymer reinforcement is equally suited to marine structures, precast concrete products, architectural installations, industrial facilities, and specialist environments where traditional steel reinforcement may be unsuitable.

    Whereas traditional concrete is typically poured, Glassfibre Reinforced Concrete is generally sprayed due to the often-complex nature of GRC products. Specialist spray guns are required for such a task, designed to align with the production processes of GRC and to accommodate the incorporation of the composite’s key component: AR Glass Fibre.
