CIVIL ENGINEERING & HYDRAULIC STRUCTURES
Bridges, dams, water intakes, or locks: we intervene on essential civil engineering structures with rigor, technical expertise, and respect for hydraulic constraints.
INTERVENE ON THE MOST CRITICAL STRUCTURES, WITH COMPLETE CONTROL
SIDON operates on essential civil engineering structures, particularly those located in hydraulic or hard-to-reach environments. Bridges, dams, locks, water intakes, quays, or dikes: we implement robust and secure technical solutions to ensure the longevity and performance of strategic infrastructures.
Targeted interventions on major structures
Our teams are trained to intervene in complex environments, where structural, environmental, and regulatory constraints require specialized expertise:
Inspection and diagnostics of submerged or semi-submerged structures
Concreting, trimming, formwork, and reinforcement work in flood-prone or submerged areas
Maintenance or repair work on existing structures
Installation of protections (anchors, nets, anti-erosion devices, etc.)
Assistance with commissioning of new or renovated structures
Our interventions can be one-off or integrated into larger projects in collaboration with general contractors, project managers, or local authorities.
A COMPREHENSIVE MASTERY OF HYDRAULIC ENVIRONMENTS
SIDON's experience in river, port, and underwater environments is a key asset for civil engineering projects. Whether it's rivers, canals, water reservoirs, or port areas, we understand the specific challenges related to currents, tides, polluted zones, or structures in operation.
Our interventions are adapted to hydraulic requirements, tight deadlines, and the challenges of ensuring service continuity for infrastructures.
STRONG TECHNICAL PARTNERSHIPS
QUALITY, SAFETY, AND SUSTAINABILITY
SIDON collaborates with key players in the construction and public works sectors. Our ability to ensure co-activity, comply with QHSE standards, and provide tailored technical solutions makes us a valuable complement to general contractors and specialized engineering firms.
Conscients de la criticité des ouvrages de génie civil, nous déployons des procédures rigoureuses en matière de sécurité, de traçabilité des interventions et de contrôle qualité. Chaque chantier fait l’objet d’une préparation détaillée, avec une attention particulière portée à la sécurité des hommes et à la protection de l’environnement.
