Castile Riven GRC Promenade Tiles – Natural Stone Effect Roof, Balcony & Terrace Tiles (297 x 297 x 12mm).

Castile Riven GRC Promenade Tiles combine the timeless look and warmth of natural stone with the durability and strength of Glass Fibre Reinforced Concrete, creating a hard-wearing, attractive surface ideal for flat roofs, balconies, terraces, patios and walkways. Trusted across the UK roofing industry and manufactured by Castle Composites—Britain’s leading promenade tile producer—these tiles offer the perfect balance of style and performance.

The Riven finish replicates the authentic texture and character of natural stone without the drawbacks. Multiple mould variations are used during production to avoid repetitive patterns, giving a more organic, realistic appearance. Available in a wide range of natural stone-inspired colours, these tiles can be easily matched to surrounding spaces or used to create contrasting, eye-catching designs.

At just 12mm thick, they’re lightweight and designed to be bonded directly onto flat roof surfaces using PU adhesive, making installation straightforward and secure.
