From 1991 until today, our company had operated lime stone quarries in Gebze and Çatalca districts (İstanbul City) which were the heart of the aggregate market. Our new address in aggregate production is called Danamandıra region which is the junction area of Çatalca and Silivri districts. Quarries in this region are operated with the collaboration of Akçansa A.Ş. of Sabancı Group. Our operations in this growing and expanding part of İstanbul take shape from the projects’ needs which are handled by private sector and government.
