Have been reading opposing opinions on the porosity of travertine, ranging from porous to impervious. Ignoring,if possible ,the natural cavities in the material... is travertine inherently porous. dunk a piece of terra cotta in water and it soon becomes apparant that it is porous as the air bubbles rise ...but travertine ?
Have come across people who are adamant that it has to be sealed to waterproof it!
