Travertine is stronger than onyx, but weaker than marble. Travertine is for cladding floors, walls, and sometimes ceilings. Travertine is easy to process, and due to lower density of stone, made of travertine parts and structures have less weight with sufficient strength. Leads to active use in creation of elements, external and internal cladding. Travertine belongs to moderately erasable natural stones therefore can be as material for steps of ladders and decorative elements of floor in places with low passability.
