WHAT ARE TRAVERTINE PAVERS? Natural Travertine Limestone and Marble Pavers are natural stone pavers quarried in the Turkish mountains and cut to size in paver thickness. Travertine (a type of very hard limestone), and marble are the same timeless materials used for building construction around the world for centuries. The Pyraminds of Egypt, the Colluseum in Rome and many of our state buildings in Washington, DC are faced with these same materials, because they stand the test of time and also because of their timeless beauty.
