HomeOur experienceDams

DRAGADOS is a world leader in the development of water- related projects, having built over 250 dams and Hydroelectric Power- Generation Plants all over the world, in fifteen countries in four continents.

The company is internationally renowned for the implementation of the latest specialized technologies in the construction of dam and water projects.

Throughout the years, the firm has contributed to the wellbeing of hundreds of communities around the world, vastly improving power production, water supply, irrigation, and flood-control systems, and fostering significant environmental improvements.

DRAGADOS has built dams of different types and materials. For dams made up of vibrated concrete, the company has constructed the following types: Gravity, Buttress, Arch Gravity and Double Arch. For Roller-Compacted Concrete (RCC) dams, we have experience in constructing Gravity RCC and Arch Gravity RCC dams. And lastly, for embankment dams we have experience with homogeneous dams, Earthfill and Rockfill dams, Asphalt-Faced Earthfill/Rockfill dams and Concrete-Faced Earthfill/Rockfill dams.

DRAGADOS also has extensive experience in the construction of hydroelectric power plants, in addition to thermal and nuclear power plants, pumping stations, irrigation ponds and storm water tanks. It has built hundreds of kilometers of waterways including water tunnels and aqueducts, irrigation and water supply networks, sewage, cooling for power stations and pipelines. We have also taken part in Environmental projects that involved improvement of watercourses and renovation of rivers in urban areas.
