Bellandra Sandstone Tiles - Natural Split Surface, Australia Beige Sandstone

Bellandra Sandstone Tiles - No Stone Less Processed & More Natural
Bellandra sandstone tiles look natural and are natural. A measure of the environmental credentials of a building product is the involvement by man and process up to the point where it is fixed to a building. On that basis this stone is a clear winner. Unlike Australian sandstones it cleaves or splits quite naturally when hit with a chisel and doesn"t need expensive machinery to saw or cut it. That"s why it is described as having a "natural split surface" - a quality very few sandstones possess. It does mean the thickness of the material varies a bit - naturally!
