Travertino - Travertine

Travertine is often used as a building material. The stone is characterised by pitted holes and troughs in its surface. Although these troughs occur naturally, they suggest to some eyes that considerable wear and tear has occurred over many years. Some installers use a grout to fill these holes, whereas others leave them open.  travertine can even be purchased "filled" or "unfilled." It can be effectively polished to a smooth, shiny finish and comes in a variety of colours from grey to coral-red. Travertine is one of the most frequently used stones in modern architecture, and is commonly seen as façade material, wall cladding, and flooring.
