Sandstone is actually a sedimentary rock formed by the consolidation and compaction of sand, which is held together by a natural cement, such as silica. Natural sandstone is an extremely hard and tough material. Sandstone is typically the youngest of the quartz-based stones, with each stone having a different level of porosity, hardness and compressive strength. Indian sandstone is suitable for domestic and commercial use. Owing to their natural beauty, sandstones are used for interior as well as exterior decoration including flooring, paving, cladding walls and floors.
