Oftentimes, there are complaints from many clients regarding the longevity of the granite flooring. The main reason being that the polished surface of the granite slabs start deteriorating after a while.
The major cause of deterioration of Granite flooring, especially in countries like India is spalling and efflorescence on the granite slabs.
This is normally a symptom of having a moisture problem; meaning the stone is being subjected to excessive moisture from beneath it. Water is migrating from perhaps outside of your house through the concrete slab and up through the granite stone. As the water travels through the soil, concrete, and stone it picks up minerals (salts) that dissolve in the water. When the water evaporates at the stone surface the minerals precipitate into a solid. Thus it expands causing the spalling or deterioration of the stone surface. It also leaves the precipitation on the stone surface which is called efflorescence which is normally white in color.
The solution is to stop the source of the moisture. Some times that means fixing a leaking water pipe or installing a French perimeter drain around your house to divert the water. Because you do have a natural stone it can be restored by having a professional stone restoration company come in and re-grind and polish the stone.
