The very important feature of natural stone is its complete restorability. Any marble surface under any condition could be totally restored by an expert.
In order to have a new flooring, there is no need to replace the marbles; it is sufficient to reopen and grout the joints, repair the damage, remove any stains, re-polish all the surfaces with special polishing machines and the floor is as new as it was just laid.

Even completely broken marble objects can be reassembled and structured by an expert, especially veined marbles are presented as new.

There is also a false myth about marble, namely that the most delicate marble is the white one; in fact, the most difficult marble to maintain is black or dark, where scratches are immediately visible as any streak on the marble remains light in color. Black marble often has stains, which are not noticeable on white marbles, therefore white marbles are the best choice for bathrooms, which must only be cleaned mechanically with sponge.
