I do not have the exact knowledge of the specifications of the Foussana Grey Marble from Tunisia. However, its worth noting that marble, in general, is a natural stone that is susceptible to scratching, staining, and chipping if not properly maintained. Therefore, marble may not be the best choice for heavy use areas such as high traffic floors.

If you want to use marble in heavy use areas, it is recommended to choose marble with a low porosity rating and high hardness rating. Additionally, proper sealing and maintenance are vital to prevent damage and ensure the materials longevity. We highly recommend consulting a professional stone fabricator or installer to help you choose the appropriate type of marble for your specific application.
