Blue Slate 40mm

Blue slate 40mm lies flat making it ideal for your driveway. Also great for mulching around borders and patios. 40mm gravels make it harder for unwanted animals digging.

Blue Slate may contain a small amount of Plum Slate and Green Slate. This is a result from when the slate is quarried, the plum and green slate seams are taken out before the blue. If you need a cleaner more even colour slate, choose the green or the plum. This is not as noticeable in the blue slate 20mm as it gets broken down into smaller pieces.
