HARTSTEINWERKE Vogtland GmbH & Co. KG operates eight quarries and three asphalt mixing plants. The company has a wide range of bulk materials out of diabas and granite stones. Materials like antifreeze gravel, gravel substructures as well as different splits and super-refined splits are offered. The diabas and granite stones are suited as supplementary materials for the production of asphalt and concrete as well as for the use as water components and for the filling of gabion cages. Due to the in-house test laboratory a continuous control of all produced bulk and mix materials can be ensured.
Aside from external clients, the purchasers of bulk materials are also the own asphalt mixing plant Hartenstein as well as several companies of the STREICHER Group.
