also known as Caithness Stone, Scottish Flagstone
A Devonian metamorphic flagstone from the far north of Scotland, Caithness is prized for its precise natural cleavage into thin, flat slabs with a silver-grey riven surface. Frost-proof and slip-resistant even when wet, it is widely used for terrace paving, entrance courts and rooftop gardens in high-end residential and hospitality projects.
Type-level physical facts shown. Per-lot lab values (absorption, flexural strength) confirmed at quotation.
Natural flagstone can be split to as thin as 20 mm while remaining stable. Thicker slabs (30-50 mm) are standard for heavy-traffic terraces.
Yes. The naturally riven surface provides excellent slip resistance, meeting typical safety standards for exterior paving without additional treatment.
