Sandstone is a classtic sedimentary rock composed mainly of sand-sized minerals or rock grains
Rock formations that are primarily composed of sandstone usually allow percolation of water and other fluids and are porous enough to store large quantities, making them valuable for exterior applications. Sandstone is mined by quarrying. It is sometimes found where there used to be small seas. It is usually formed in deserts or dry places like Rajasthan.
Hardness and Porosity characteristics of sandstone make it applicable for Paving, Exterior or Interior, Flooring, Walling etc, available in variety of colors, sizes , shapes and Finishes.
