Blue Slate 20mm
Available in poly bags or bulk bags
Blue Slate is a naturally flat and angular material. Heather blue in colour, the material looks beautiful when wet or dry. Blue slate can be used within many applications but is most commonly used for mulching of borders.
Our smooth green slate paving slabs are available in 600x800mm single sized packs, and you can choose from 7.2m2 or 14.4m2 options, calibrated to 25mm deep. Green slate with calibrated depths is much easier to lay.
