Marble flooring give the interior an elegant appearance, however marble floor have many problems because marble is sensitive. Installing marble at floor is more sensitive than wall. At wall dust and water will slide away from marble, but on floor it remain at marble ruining it surface.
Level surfaces problem
One of marble floors disadvantages is surface level. After extracting marble from quarries , marble cuts into slabs using band saw or bridge type saw. Band saw produce a wave surface, comparing to bridge type saw it’s produce a straight surface. During installing of marble flooring, craftsman has to level the floor surface. IF the marble cut using band saw machines craftsman has to arrange the tiles in a way to avoid different surface level.
To check if marble surface leveled, keep you eyes at floor reflection, the reflected photo has to be straight not sporadic or wave. In case that marble surface isn’t leveled, it requires grinding marble and polishing it. Personally I don’t recommend grinding marble because original grinder will lose for longer period.
Fragmentation of marble Surface
Another marble floors disadvantages is surface fragmentation. Marble floor has to be always clean, where dust and sand at floor with people movement will scratch marble surface, marble will lose reflection of marble. When small area in marble scratched it will affect other areas and will make the surface look bad. Although i prefer grinding marble only if the marble surface scratched, it will return as it installed last month.
Water as we discussed before, its ruin marble. Grinding marble surface can protect from natural factors like dust and water, but marble sides and back will gain water. It will gain water if there is a problem with sewage or water supply system underneath the marble. Therefore marble sides and back has to be protected against water and moisture.
