Grey sandstone has a naturally riven surface and split sides. Consistently grey in colour, the material looks stunning in most garden enviroments. Sandstone is a sedimentary rock formed from sand size grains and is ideal internally and externally. Suitable for pathways, garden patios and public areas, riven sandstone paving is hard wearing and provides a natural slip resistance. Being a natural material, it is prone to colour and texture variations. Sandstone is a fantastic alternative to more expensive paving options such as Yorkstone and Cotswold.
