Durable. While limestone has a Mohs hardness of 2 to 4, it has a crushing strength of up to 180 MPa, four times that of concrete, which has a crushing strength of 40 MPA. Limestone has a high mineral content, making it ideal for floor tiles. This natural stone has proven to be long-lasting.There are lots of different stone flooring types, including: marble, limestone, sandstone and granite. However, the natural stone floor you choose will depend on the room in which you are laying it and the look you want to achieve.
