HomeOur experiencePorts

Since its inception in 1941, Dragados has been a construction company with a clear maritime vocation, specialised in the design and construction of marine work and with the experience, technology, and specialised equipment necessary for the development of major port infrastructure projects worldwide.

Over the years, and with the support of its Technical Department, Dragados has excelled in the quality of its work on marine and port projects and for its willingness to guarantee contract completion dates on technically complex projects and those with special construction methodology requirements.

During the years of large investments on port projects in Spain in the late twentieth century and early twenty-first century, Dragados worked actively on new port construction and expansion of existing port facilities, finished the construction of a large number of breakwaters and docks, and improved port facilities so that they could better respond to an ever increasing marine traffic, especially that of container ships. Much of the noted work had an important and positive geographical and climatological conditioning effect, and some of those projects have become icons in the marine construction field worldwide.


Dragados has worked on and completed 543 projects within the marine construction field, which can be classified by type, as follows::

  1. 57 Expansion and new port projects
  2. 173 docks and mooring berths, including the manufacture of approximately 3,000 hollow core cellular box reinforced concrete caissons
  3. 17 Vertical breakwaters (new construction)
  4. 100 km of sloped and rubble mound breakwaters
  5. 31 Large land reclamation and port esplanade construction and paving projects
  6. 200 million cubic meters of dredging
  7. 93 coastal projects: waterfront areas and beaches
  8. 41 outfalls and underground piping
  9. Facility construction for 6 shipyards, including slipways, graving docks, and dry docks
  10. 19 Bridges whose foundations, partially or completely located in sea waters, required the application of project-specific construction techniques and methodology
