Don't be fooled. Weathered Riven paving may look & feel like real stone shaped by the ravages of time, but it's actually a pressed paving that's available at a great value price. Pointing reinforces the illusion of real stone with the paving edges acquiring a convincing fettled look. Each pack contains 36 units. When laid using a 10-15mm joint each pack contains enough paving slabs to cover 7.60m 2. Thickness: 35mm
