GRC is a blend of long strand fibreglass and concrete applied using a special technique that chops the fibreglass and adds the cement mix at the same time to ensure maximum strength and longevity. Pietro Stoneware is a premium grade of GRC and is meticulously hand finished to remove cast lines with consistent colour and finish.
Our GRC doesn’t reinforce the layers using steel which adds additional weight and can rust and expand over time, leading to cracking. Some other concrete products use natural fibres (like jute), which hold moisture and will rot over time.
The secret is in our unique manufacturing technique, allowing us to create thinner walls that make each piece much lighter and easier to move without losing any strength. Reactive oxides, water and solvent based paints are used to colour each piece, providing a durable exterior finish. The exposed surfaces are coated with a sealant that protects the concrete material and creates a water repellent layer that limits staining and scratching on the surface layer.
- Lightweight, yet strong
- Pre-sealed internal walls
- Huge range of styles and colours
