Travertine Alabastrino Polished 18x18

Travertine is a product of nature. As such, it is bound by its inherent characteristics and limitations. As with all natural stone, Travertine requires periodic maintenance. The fill used in the naturally occuring voids, pores, and holes during the stones finishing process is not guaranteed for the life of the tile.
It can and will pop out with common wear and tear.
Voids in the stone may cause the surface to ''crater.''
This is not an unexpected outcome and can be remedied with routine maintenance.
