Travertine is a form of limestone also known as Calcium Carbonate which is deposited by mineral springs, especially hot springs. Travertine tiles are natural such as Marble, Slate, Granite, Limestone and Onyx.
The characteristics of Travertine tiles are the holes within the stone which are caused by carbon dioxide. Due to this natural formation process Travertine have a low density, porous and full of holes.
The faces of Travertine tiles are filled, it should be noted that there are always other voids below the surface and these will eventually show as the floor wares in heavy foot traffic areas.
Travertine tiles are available in the following finishes: Filled & Honed (most popular), Tumbled, Polished, with or without a chiselled edge.
