Canadian Black Slate

Canadian Slate is crushed slate, which is why it has a flat, disk-like shape. This shape gives the chippings a special appearance. When dry, the slate is anthracite in colour, and when wet it is almost black .

Our Canadian Slate is suitable for use as an ornamental crushed stone on garden paths and patios, and is even strong enough to use in the driveway, possibly applied as chippings slabs!
