Willow Sandstone Tiles & Himalayan Stone Pavers
Willow Sandstone - No Stone More 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.
Stone Colours & Texture Enhanced with Natural Split Surface
Stone that splits naturally along planes reveals pallets of vivid colour not seen in stone with processed surfaces. The topography of the surface is intricate and has character, depth and grain - as you will see in the images below. Stone flakes that are occasionally seen are the best indicators that the stone is high enough quality to split naturally - they are easily removed before fixing.
