We carry out inspection, maintenance, cleaning, and repair operations on industrial structures, often strategic or in sensitive environments: SEVESO zones, sedimentation basins, wastewater treatment plants, submerged pipelines, metal or reinforced concrete structures. Our expertise in QHSE standards and confined space interventions is a guarantee of safety.


SIDON Construction is regularly mobilized for works on quays, dikes, jetties, pontoons, floating structures, mooring systems, and coastal protection works. We also provide dredging, trimming, underwater welding, and heavy-duty support services. Our experience in port areas extends across the entire French maritime coastline.


Our teams work on locks, dams, canals, navigation piles, beacons, and all submerged structures essential for the safety and regulation of waterways. We also carry out dredging, the installation of underwater structures, the rehabilitation of old works, and the inspection of infrastructure.
We provide support for civil engineering works: formwork, concreting, injection, reinforcement, and trimming in submerged or hard-to-reach environments. Our teams are trained to work alongside other trades, in perfect coordination with general contractors, project owners/management, and engineering firms.


EVENT SERVICES
We provide logistical and technical support for event projects in complex environments: installation of structures, specific anchoring, underwater or height interventions. Our teams are trained to work in coordination with set designers, production companies, television crews, and event organizers, respecting deadlines and artistic requirements.
