Engineered solutions for durable and safe marine infrastructure

What we do: VSL capabilities for Offshore & Marine Structures

Offshore and marine structures operate in highly demanding environments, exposed to salt water, waves, wind, dynamic loads and, in some cases, seismic actions. These conditions impose strict requirements on foundations, structural systems and construction methods. VSL delivers integrated structural and geotechnical solutions that improve durability, constructability and long-term performance of ports, coastal infrastructure and offshore structures.

What we do: VSL capabilities for Offshore & Marine Structures

Marine projects require reliable water control, durable concrete solutions, controlled handling of heavy components, and protection against dynamic actions. VSL combines complementary capabilities to support design, construction and long-term performance in ports, coastal works and offshore environments.

Cut-off walls and waterproofing systems

Cut-off walls limit water migration in the subsoil and ensure watertightness of marine and offshore structures. They protect foundations and buried structural elements in ports, quay walls and coastal infrastructure where groundwater control is a critical design requirement.

Heavy lifting

Heavy lifting solutions enable the safe handling and installation of large components in offshore environments where conventional cranes are constrained. Engineered lifting methods improve operational control and reduce exposure to weather-related delays during marine construction.

Post-tensioning for marine structures

Post-tensioning enhances the durability of concrete structures exposed to aggressive marine environments. By limiting cracking and protecting reinforcement from corrosion, it improves watertightness, structural performance and material efficiency in offshore and coastal applications.

Seismic protection and vibration control

Seismic protection and vibration control systems reduce the effects of earthquakes, wave-induced vibrations and wind loads on marine structures. These solutions improve structural stability, safety and long-term performance under dynamic environmental conditions.

Slab-on-grade for ports and marine areas

Slab-on-grade systems provide an efficient solution for large port and marine surfaces. By reducing construction joints, they limit cracking, accelerate construction and improve long-term performance of areas subjected to heavy loads and harsh exposure.
