Natural stone
Slate: layered, rustic natural stone
A fine-grained stone that splits into natural layers for roofing, flooring and cladding.
Material overview
About Slate
Slate is a fine-grained metamorphic rock formed from clay-rich sediments. Its defining feature is cleavage: it splits naturally into thin, flat layers, each with a textured face.
Slate is valued for its muted greys, blacks, greens and rust tones, and for a natural, tactile character that suits rustic and contemporary design alike.

Project suitability considerations
- Thickness variation: cleft slate varies in thickness. Ask for calibrated tiles for floors.
- Layering: some types can flake at the surface. Choose proven grades for floors.
- Colour change: some slates shift in tone after installation or sealing.
- Slip resistance: natural cleft faces provide good grip.
