These materials were originally deposited as soft sediments being laid down as beds underwater by a variety of chemical, biological and physical processes. Over millions of years the sediments were buried, compressed and became cemented by precipitation from mineral rich waters contained therein. The resulting rocks are found in beds of various thicknesses that possess natural jointing systems. Generally the majority of Limestone are composed of calcium carbonate. The fossils and other sedimentary structures that these rocks contain provide a key to the environment under which they were formed.
For the stone industry, those Limestone that have a porosity of less that 5% and take a full polish are termed hard limestone. Example of this is Travertine. Many stones termed marbles are in fact hard limestone. Masoning characteristics, tradition and the fact that these stones take a high polish are reasons why some are called “marbles” when in fact they are hard limestone.
This material has very little graining and can vary much in surface density. Honed finishes give an authentic look as floor covering but requires sealing to minimize staining, not recommended in high traffic commercial areas
