The smallest size of graphite grey slate chippings. This slate is an environmentally friendly by-product from the Welsh roofing slate industry. Alternative names for this slate are sometimes used like Grey Slate or Charcoal Grey Slate. It's a neutral dark grey colour so won't distract from its surroundings when laid. There is a possibility that mixed in with the grey slate there might be the odd piece that is a different colour. Sometimes this may even be in the same piece of slate. The 20mm grade is the more popular of the two sizes for use on driveways and paths as it tends to bed down and knit together making it an ideal surface for walking on. It's also often used for water features, ponds, screescapes, borders, mulching and general decorative landscaping. The approximate length of the chippings ranges between 10-30mm. The recommended depth for laying is roughly 30-40mm. Also available... Graphite Grey Welsh Slate Chippings 40mm
