About Stone

Indian Sandstone is a sedimentary rock composed essentially of quartz grains cemented by siliceous, felspathic, calcareous cementing matters. The durability and strength of these rocks depend on the cementing material. The best quality sandstone, for building purpose, should be of fine grain and uniform texture. Sandstone is the youngest of the quartz-based stones, which eventually turns into quartzite as the sandstone is subjected to heat and pressure. Textures within the sandstone layers such as cross bedding, ripple marks, and mud cracks, are clues to the origin of the layers as shallow, inter-tidal or delta sediments. The colours of sandstone depend on the mineral contents and impurities in the sand. Generally, the sandstone is available in red, beige, pink, green, grey, brown, yellow, mint, teak, and in rainbow colour.

Sandstone was a common building material in India for larger structures, before reinforced concrete came into use in the middle of late 1800’s. Nevertheless, it is still put into various purposes such as for flooring or as paving materials since they are dug out from the ground in individual layers. Some sandstone is honed for a smoother finish and used for both interior and exterior applications. It is also used as flagstone for residential applications.
