MARGA GREY & MARGA DARK GRANITE

Our Marga Grey granite is a fine grain grey granite, very compact and extremely hard. Its grey color is quite homogeneous and it´s ideal to achieve a chromatic continuity to face large projects. We have a great quarry with large reserves, so the supply is completely guaranteed.

This granite is perfect for manufacturing any kind of product, either public or private works. We can supply tiles, kerbstones, paving-sets, stone walls, palisades, columns, arches and any architectural element with two finishings: saw cut and shot-peened.

PETIA & PETIA CREAM GRANITES

Our Petia granites have a great presence because of their visual force. They are a medium-large grain granite with two tones: white and cream. Both tones are perfect to face any kind of project, due to the magnificent quarry which are mined from, that counts with large reserves. Of course, due to their physical characteristics, they admit any kind of finishing.

Negro Oca

Negro Oca granite is a compact rock with irregular fracture. It is extracted in Spain. Its operating fronts are of variable length and with irregular fracturing, from which large blocks can be extracted (it has abundant reserves).
It admits any type of finish and does not show important alterations or loss of polishing. Can be used indoors and outdoors.
Predominant black and dark gray grains, mixed with other smaller targets. Is considered medium grain and uniform.
