This Blue/Grey Sandstone gravel is more commonly known as Gritstone or Mudstone. The stone falls under the category of sedimentary rocks, formed by the accumulation or deposition of mineral or organic particles.

Due to the very nature of Mudstone (fine grain clay particles), there will be a build-up 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.

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.

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 stone’s true colour will emerge, making your project glow.

If your looking for other blue chippings, take a look at our Blue/Black Limestone or Blue Elvan. These offer great alternatives for your garden project.
