A 20mm gravel known locally as Clean Granite or Cornish Chippings. This product falls under the category of Igneous rocks, formed by the cooling and solidification of magma or lava.  These 20mm chippings are quarried, packaged & sold in Cornwall.

Our 20mm Silver Grey Granite is graded with the biggest stone no larger than 20mm. This can mean that smaller sizes of 10mm can be found within this product.

As this is a natural product, the colours may vary between batches. When bagged, the stone will usually have a covering of dust which can make the stone appear a different colour. Once the dust has washed away, the true colour of the stone will emerge.

  • Bulk/Jumbo bags are filled to an approximate weight of 830kg.
  • Small polybags are filled to an approximate weight of 25kg.
  • Free sample bags are filled to a weight of 1kg.
  • Loose material is supplied on a per ton basis. This is available locally & nationally by request.
