A sedimentary rock made up of tiny grains of quartz and, often, feldspar bonded together naturally with silica, calcium carbonate, iron oxides and clays. Most commonly available in buff to red colours and while not solely, the material is especially sourced from areas within the UK and Germany. It’s presence on projects from historic buildings to modern settings is testament to sandstone’s adaptability. Traditionally produced by splitting layers from a block extracted from the quarry, to offer a riven finish, this material can also be supplied with a range of textured finishes, which further enhance sandstone natural slip resistance values.
