About us

GRANDEMAR holds a special place amongst the producers of building materials in Romania. Its quarries are placed in the centre of Transylvania where the bases of industrial extraction and processing of building stone were established: beginning with 1873 by opening Poieni Quarry under private patronage.

Poieni was the first of the quarries to be endowed with elements of industrial technique and technology within the field of stone extraction and processing such as: compressed-air drilling and mechanical shattering by crushing the rock. Since that year and until present time, the mining activities in the area developed continuously, new quarries were opened: Bologa, Morlaca, Valea Drăganului, etc. The rocks in the region have special characteristics which confer a great quality to the quarry products. These meet permanently the quality standards requested by the railways or the road builders. Over the years, the quarries had successively different types of organization or administration, but Cluj has always remained the administrative centre to influence the economical, financial, and technological activity of this sub-branch.
