About Piatra si Nisip

The Andesite quarry from Seini was opened for the first time in the year of 1891, being taken over by several private enterprises until 1949, when it was nationalized due to the communist regime.

Since the beginning of the quarry, the stone has been exploited with the help of workers who lived in Seini and around the city. At that time, rudimentary tools were used and the stone was transported by animals.

Since 2009, the quarry has been part of the Kirchdorfer group. Thanks to the massive investments that have been made and the infusion of capital, the quarry has become one of the main players in the stone industry.

Using new technologies and the latest generation equipment we are ready to produce annually over 400,000 T of crushed stone.

Since the exploited basaltoid andesite has a very high hardness, it has been used for road construction, asphalt manufacture and even monument construction because it behaves very well in polishing.

Because we have a good cooperation between our company and the local community, and also a  good collaboration  with our clients, we create the premises for a continuous development of this quarry
