I cannot make a precise judgement on the suitability of Lappia Green Marble for heavy use areas. However, marble is a natural stone known for its durability and can be used in high traffic areas such as floors, walls, and countertops. However, it is important to note that all natural stones are porous and can be susceptible to scratching, staining, and etching. Thus, proper cleaning and maintenance should be undertaken to ensure longevity and durability. It is therefore important to consult with a professional stone fabricator or supplier to determine the suitability of marble for a specific heavy use area.
