HomeOur experienceDams

Dragados is a global leader in hydraulic projects. We have built over 250 dams and hydroelectric power plants worldwide, in fifteen countries across four continents.

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

The company 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 acquired extensive experience building dams of different types and materials mostly concrete dams (gravity, arch-gravity, double arch, buttress, and roller-compacted (RCC)), and embankment dams (homogeneous, zoned, concrete-faced (CFRD) and asphalt-faced (AFRD)).

Dragados also has extensive experience in construction of hydroelectric power stations, in addition to thermal and nuclear power , pumping stations, irrigation ponds and storm ponds. We have built hundreds of miles of waterways including water tunnels and aqueducts, and irrigation water networks, water supply, sewage, cooling power plants and pipelines. We have also participated in projects to recover the riverbanks, introducing environmental improvements in the waterways and restoring rivers in urban areas.
