Tile Tech's range of Travertine series porcelain pavers have significant number of advantages over natural stone that have been traditionally used in such projects. Porcelain pavers have a water absorption of less than 0.1%, not only it is exceptionally stain resistant, but water cannot penetrate, so it avoids issues of freeze thaw cracking which can be a problem in certain climatic zones with natural stone paving. "Cool-Roof" colors are also available to meet high SRI values and LEED points within the porcelain series.
