Travertine is a naturally porous sedimentary stone characterized by countless small surface holes and voids—an inherent feature of its formation. These surface holes may vary in size and are part of what gives travertine its unique texture and appearance.

Because of its high porosity, travertine can absorb water and is considered a permeable material. This natural permeability is one of the reasons why many builders, landscapers, architects, and designers choose travertine for outdoor applications, especially in warm climates.

On pool decks, travertine pavers offer a surface that many find to be slip-resistant under wet conditions. Some laboratory tests have even shown that wet travertine can be less slippery than when dry, making it a popular choice for areas around water.

Travertine Mart’s Premium Select Grade Travertine Pavers are selected for a balance of natural porosity and density. While still showcasing the surface holes typical of travertine, this grade offers a structure that performs well in a variety of climates—including those with freeze/thaw conditions—when properly installed. As always, you should consult with a professional installer to ensure appropriate installation practices for your region and project needs.
