Travertine is a sedimentary rock which is formed by the transformation of limestone. Carbon-dioxide which water passes through limestone, dissolves it and becomes saturated in it. Changes in temperature and pressure occur and the carbon dioxide is released into the atmosphere as it reaches the surface of the earth. As carbon dioxide is released at these hot springs, the limestone loses its ability to remain in solution and re-crystallizes over tiny plants, algae and moss. Over time layers and layers of this new stone build up which is the travertine we see today.


When regular maintenance procedures are no longer adequate, complete restoration will be necessary. Problems like cracked, loose or chipped tiles or a desire to have a different finish on the stone all require complete restoration. Travertine is sometimes incorrectly called travertine-marble due to its ability to be polished to a high shine. It is possible for us to polish a honed travertine which will give it more depth of color. If the travertine is unfilled, we can fill it and give it a honed or polished finish. This is done using the diamond grinding system and special calcite polishing powders. It really is a very versatile stone which can be restored in a number of different ways. Colored epoxy resins or polyester fillers are used to assist in filling holes when the stone is polished. Grout or cement based fillers are used if the required finish is honed. Stains are removed using a poultice and deep alkaline cleaning prior to grinding and honing. It is sometimes wrongly assumed that because travertine has an abundance of holes that it is extremely porous. It is actually less porous than marble and limestone however it still requires the application of a penetrative sealer in order to offer a good level of protection from staining once restoration is complete.
