They create a level, attractive and free-draining paved surface while allowing access to the area beneath the slabs when required.\n\nThe Riven finish combines the texture and warmth associated with natural stone with the strength and durability of glass fibre-reinforced concrete (GRC). This provides a practical paving solution that offers a more natural appearance without compromising on robust performance.\n\n\u003ch3\u003eNatural-Looking Riven Finish\u003c\/h3\u003e\n\nA selection of mould finishes is used throughout the Riven range to help avoid a repetitive appearance. The variation between the moulds gives the installed paving a more natural look, similar to the subtle differences found in natural stone.\n\nThe available colours have also been carefully selected to complement natural stone shades, giving you plenty of flexibility when coordinating the paving with surrounding walls, landscaping and other design elements.\n\n\u003ch3\u003eRemovable and Easy to Access\u003c\/h3\u003e\n\nWhen installed on suitable supports or pedestals, the slabs can be removed when access is needed to the surface below. This can be particularly useful for inspections, maintenance, repairs or accessing services beneath the paved area.\n\nThe removable design provides practical long-term flexibility without requiring the entire paved surface to be permanently fixed in place.\n\n\u003ch3\u003eAvailable Finishes\u003c\/h3\u003e\n\nCastle Composites Riven Promenade Slabs are available in eight finishes:\n\n\u003cul\u003e \u003cli\u003eBuff\u003c\/li\u003e \u003cli\u003eGrey Marbled\u003c\/li\u003e \u003cli\u003eLight Grey\u003c\/li\u003e \u003cli\u003eRed\u003c\/li\u003e \u003cli\u003eSlate\u003c\/li\u003e \u003cli\u003eTerracotta Marbled\u003c\/li\u003e \u003cli\u003eTerracotta\u003c\/li\u003e \u003cli\u003eWhite\u003c\/li\u003e \u003c\/ul\u003e\n\nThe range includes subtle shades such as Buff, Light Grey and White, darker options such as Slate, and warmer finishes including Red and Terracotta.
