Natural occurrences of travertine have formed spectacular terraces, walls and dams throughout the world. One of the most famous sites is Pamukkale in Turkey, which contains seventeen hot springs and a series of travertine terraces which reach to a height of 160 metres. The natural stone [link widoczny dla zalogowanych] terraces have formed from deposits left by running water rich with carbonate minerals. The Ancient Greco-Roman city Hierapolis was [link widoczny dla zalogowanych] built on [link widoczny dla zalogowanych] [link widoczny dla zalogowanych] top of the hot springs [link widoczny dla zalogowanych] in the second century [link widoczny dla zalogowanych] BC and the site is now an archaeological museum and World Heritage tourist site.
Quarried Travertine is usually 50 million years old, making it a very special material to use in construction and landscaping. As with any stone of this age, the travertine used in pavers and other building materials is distinctive for its natural variations in colour, texture and patterning.
Travertine is a sedimentary stone, formed by the rapid precipitation of calcium carbonates in mineral springs. It is classed as a type of limestone. It forms naturally at the mouths of hot springs and in limestone caves where it forms stalactites, stalagmites and other cave formations or deposits (also known as speleothems). is a light coloured stone, available in shades of white, tan, cream, or sometimes coral, and commonly has concentric bands or fibrous stripes of colour.
Travertine is extremely strong, it is recognised as being twice as strong as concrete, making it suitable for use [link widoczny dla zalogowanych] in all areas of construction, from pool surrounds to indoor flooring, bench tops, patio pavers and driveways. Travertine is salt resistant, non-slip and remains cool in hot [link widoczny dla zalogowanych] weather, making it the [link widoczny dla zalogowanych] perfect stone for any outdoor application.
Travertine is mainly sourced from Italy or Turkey, as well as some [link widoczny dla zalogowanych] quarries in the U.S. states of Oklahoma and Texas. It has been quarried and used for building in Italy since Ancient Rome and has a great historical [link widoczny dla zalogowanych] significance. The stone was used, for example, to build the famous colonnade of St. Peter's Square in Rome in 1500. Travertine was also [link widoczny dla zalogowanych] chosen by Michelangelo [link widoczny dla zalogowanych] for the external ribs of the dome of St. Peter's Basilica.
Travertine can be purchased in two forms, either filled and honed or unfilled, tumbled and honed. Filling is sometimes used to give the stone a smoother appearance and to compensate for naturally occurring holes in the surface. Travertine can be polished to a high [link widoczny dla zalogowanych] finish for elegant [link widoczny dla zalogowanych] indoor applications, or left in its natural state for outdoor paving and wall cladding.
