The dredging sector represents a long-standing market for Technogenia. Companies in this field have always had a great need for surface coatings, in order to contend with the high level of abrasion to which their equipment is exposed. With its Technosphère® beads, Technogenia is able to provide the perfect solution to meet its customers’ needs on their worksites.

The dredging sector is divided into two types of market. The first of these concerns dredging contracts, including not only the performance of dredging operations and associated maintenance (e.g. deepening harbors and creating canals), but also backfilling operations (e.g. creating ore terminals and artificial islands, and enlarging various other land masses). The second relates to offshore contracts (e.g. pipelines and platforms).

Technogenia also performs in dredging operations in the mining sector: Dredging of mineral sands, such as zircon, ilmenite and rutile.
