Dredging and reclamation

Dredging is a fundamental activity for the maintenance of wharves and marinas. With our equipment (CSD dredger, pontoon cranes and barges) we intervene for the cleaning of wharf legs, maintenance dredging of marinas, maintenance dredging of commercial ports and coastal shelters as well as beach resurfacing.

For the extension or creation of new port infrastructures, our mastery of this activity enables us to deliver ready-to-use projects to our clients.
