Although specialized in all types of construction projects, our business family is nevertheless the most famous for implementation of hydrotechnical projects, especially dams. Hidrogradnja's reference list is decorated with 48 various types of dams constructed so far: concrete dams, both gravitational and arch dams, embankment dams with clay or reinforced concrete core, embankment dams with gabions, and gravitational dams of rolled concrete.

If we added up the volumes of artificial accumulations that Hidrogradnja has made by its construction of dams, we would obtain an accumulation of 16 BN m3 of water – almost a little sea.  

Hidrogradnja's list of hydrotechnical projects also includes reconstruction and development of watercourses and bank protections, and construction of ports. One of the biggest Libyan ports – sea port in Misurata – was constructed by Hidrogradnja in collaboration with the company PIM.

The spectrum of Hidrogradnja's hydrotechnical projects consists of numerous sewage and water supply systems of the towns throughout the world.
