At Kostak we knew how to find our competitive advantage on the market, through our organisational skills, our diversity and expertise.

We are responsible for a wide range of construction works, as well as the reconstruction and maintenance of local and regional roads, pavements and parks, squares, streets and crossroads.

We undertake all kinds of ground works, the sanitation of quarries and landslides and the demolition of buildings.

In the Posavje region in 2005 we won the important contract for the preparative construction works of Hydro Power Plant Blanca (LOT A1), a project which has now been successfully concluded.

Working with local partners, we blend local skills with our own skilled and experienced workers, with management teams who can undertake the required organisation.

Working in partnerships, we were awarded (LOT A2) of the same project, for works on the Krsko Hydro Power Plant.

We are also involved in the reconstruction of the sewage system in the Municipality of Krsko and at the reconstruction of the square in Leskovec.

What better references could we offer than the success of these demanding and comprehensive construction projects?
