The Travertina Raw patio slab combines the elegant appearance of natural travertine with the enhanced durability of concrete, fortified by our advanced factory-sealed Klean-Bloc technology. By incorporating Klean-Bloc, this product not only mimics the beauty of natural travertine but also offers additional advantages. The application of Klean-Bloc imparts a subtle sheen to the slab, intensifies its color vibrancy, and establishes a protective layer against stains and everyday wear. These exceptional benefits are exclusive to our product and are not typically found in natural travertine.
