Description

A 20mm Blue Sandstone gravel known locally as Gritstone or Mudstone. This product falls under the category of sedimentary rocks, formed by the accumulation or deposition of mineral or organic particles. These 20mm chippings are quarried, packaged & sold in Cornwall.

Our Sandstone is graded with the biggest stone no larger than 20mm. This can mean that smaller sizes of 5-10mm can be found within this product.

Due to the very nature of Mudstone (fine grain clay particles) there will be a buildup of fine sticky clay amongst the bag but once laid this will wash down from the surface,  revealing the clean 10-20mm gravel on top.

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