Travertine tiles can crack or chip under high mechanical stress, heavy dropped objects, or shifting subfloors because travertine is a relatively soft, porous sedimentary stone compared to dense igneous rocks like granite. If travertine is installed over an improperly leveled subfloor without adequate mortar coverage, hollow spots form beneath the tiles, making them highly susceptible to cracking when subjected to heavy furniture loads or concentrated foot traffic over time.
