Sandstone/Limestone
The main use of sandstone is to clad walls and floors because of their architectural properties and for decorative purposes because of their natural beauty. These are available in many colors, textures, sizes and thickness.
Limestone is the most abundant of the non-clastic sedimentary rocks. Limestone is produced from the mineral calcite (calcium carbonate) and sediment. The main source of limestone is the limy ooze formed in the ocean.
