Product Information
40mm Blue Slate Chippings offer a more rugged texture than the finer 20mm option. When dry, the slate has cool blue-grey tones; when wet, the colour deepens to a dramatic, almost navy-blue shade. The natural mix of colours ensures variation, giving each installation a distinctive, high-quality look.
