Construction aggregates
Aggregates produced within the gneiss deposit “Doboszowice 1” are widely used in road, railway, hydrotechnical construction and as aggregates for concrete. Gneiss mixtures, crushed stone and wedge are used, for instance in the construction of motorways, and in the layers of basic and auxiliary substructures of main communication routes.

Roads and railways
Gneiss from Doboszowice is used in construction of both road and railway routes. Durable stone is one of the most important and basic elements in the construction of new transport pathways. Our aggregates have been used in the construction of such roads as the DK46 (ring road of Nysa), the A4
and the A1 motorways in the Silesian Voivodeship. The materials are produced in compliance with the following standards: PN-EN 13043, PN-EN 13242, PN-EN 13450
