When millions of years ago nature produced this wonderful raw material, this happened in varying qualities. The stone that originates from slow sediment settling can be found today with granules ranging from 0,03 to 3 mm. This means that the simple grains which build the structure of sandstone differ one hundredfold. Sandstone is not simply Sandstone. For our customer we choose sandstone from northern India with especially fine granules. This particular stone has a high level of density, giving it durability, hardness and resistance to frost.
