The term natural stone refers to the stones that are produced from the mountains such as Travertine, Limestone, Slate, Sandstone, Granite, and Marble. Each of these stones has varying characteristics that sets them apart and are good choices as floor tiles. However, a few things need to be kept in mind before taking your final decision. The first thing that needs to be checked is the absorption ratio, which means how porous a material is as the more porous it is, the more susceptible it will be to developing cracks.
One also needs to check the coefficient of friction resulting due to expansion and contraction during climate changes and whether it is used in an area which is more slippery and thus requiring a higher coefficient of friction. The major advantage of using a natural stone tile is the fact that these tiles are very eco friendly and non-polluting. The use of these natural tiles helps one to feel re-connected with nature and it gives the house a sense of uniqueness and great looks.
