White Stone

 La White Stone The White Stone is a calcarenite type stone, it’s a fine grain sedimented rock made up mostly of calcite, quartz and dolomite that has a cement and calcitic matrix and hints of siliceous cement. The calcarenitic rocks are included within the commercial varieties of sandstone as they are rocks between sandstone and limestone and that are distinguished for the presence of fossil remains and for presenting a carbonated matrix.  compuesta principalmente por calcita, cuarzo y dolomita, que presenta una matriz de cemento calcítico e indicios de cemento silíceo. Las rocas calcareníticas se engloban dentro de las variedades comerciales de las areniscas al ser rocas a caballo entre las areniscas y las calizas y que se caracterizan por la presencia de restos fósiles y por presentar matriz carbonatada.

    La White Stone por sus propiedades mecánicas Because of its chemical and mechanical properties, the White Stone is used for coatings and pavements (both interior and exterior) of public and private usage, furthermore it’s also used for ornamental elements; such as benches, columns, shields, molds, copings and more. And finally it’s also used for the restoration of old buildings.

   The most common superficial finishes are the saw cut, bushhammered, polished, semi-polished and brushed al corte de sierra, abujardado, apomazado (semipulido) y cepillado.  

La White Stone The White Stone can easily withstand different climates, evidence of this are the different constructions made with this variety; Guernica-Bilbao (High humidity climate) Salamanca (cold climate) Sevilla (warm climate) and in different regions of the south east of Spain (in high salt conditions). Furthermore, it is also necessary to highlight the fact that this material doesn’t change over time neither does its resistance to glide therefor it is also used when building swimming pools.
