LIghtweight Concrete Ornate Designs

GRC New Zealand produce custom, Glass Reinforced Concrete (GRC) ornate designs for exterior use in spaces such as plazas and pedestrian zones, parks, and transportation projects. Complex shapes, curves, profiles and fine detail are all possible with GRC for a range of applications including feature wall panels, screens, barriers, planters, and works of art. Suitable also for interior features such as corporate foyers.

Moulds can be generated from computer generated scans or drawings, GRC New Zealand can provide a total design service. 

Glass Reinforced Concrete (GRC) is a versatile lightweight composite material that can be cast in moulds, allowing it to be made to virtually any shape.  GRC can be up to 75% lighter than traditional precast concrete. This provides cost savings in transport, handling, and installation, and provides flexible design options. GRC can be painted or coloured to almost any colour using a pigment oxide added to the mix at the time of casting.

GRC is notable for its durability, seismic capabilities, chemical resistance, non-combustibility and good sound/heat insulation properties. The GRC composition can be enhanced to provide additional resistance to impact, weather, and graffiti.

In-Service History

GRC was developed as a corrosion free alternative to traditional steel reinforced concrete in the 1960s.

GCR New Zealand has produced GRC solutions for New Zealand since the early 2000s.

Other Performance Attributes

GRC is notable for its durability, seismic capabilities, chemical resistance, non-combustibility and good sound/heat insulation properties.

Lightweight and Strong:

  • GRC is a high impact resistance material with a strength-to-weight ratio superior to most other materials
  • GRC has high compressive and tensile strengths
  • The glass fibre has a tensile strength 3 to 4 times greater than the equivalent steel fibre

Durability and Maintenance:

  • The weathering characteristics of GRC are equal to any precast material
  • Unlike traditional reinforced cement, GRC uses alkali resistant (AR) glass fibres throughout the matrix to provide reinforcement so is not at risk of corrosion, and does not require further maintenance
  • Specialist products are available offering additional resistance to impact, weather, and graffiti

Environmental Information:

  • GRC is generally cast in thin skin sections which consume fewer raw materials and energy during manufacture
  • The reduced weight and thickness of GRC panels can provide significantly lower environmental impacts during transportation to site and during installation
