The name porcelain stoneware refers to a type of tile that are ideal for pavements and wall tiles. In this class of material the raw material is based on inorganic non-metallic substances which are first formed and then made mechanically resistant through a thermochemical treatment. The tiles in porcelain stoneware made by MOMBINI can be square or a rectangular shape, depending on the use.
The extremely low grade of absorption and the surface R9 or R10 make it ideal for the areas with little presence of water. The precision of the tile, which is made by using moulds, makes sure that even trucks or trolleys with hard wheels make little noise on this floor without joints.
We would like to point out that most of the floors for non-industrial use (in the house or in the office) are made with this material; the aesthetic result is exceptional because you can imitate every type of material.
