Repair & Preservation for Marine Structures
Restore resilience in harsh saltwater environments
Marine structures are constantly exposed to chlorides, waves, tides, and impact, which accelerates wear and degradation. From spalling concrete to corroded structural steel elements, visible and hidden defects can quickly escalate and compromise service continuity.
VSL helps restore safety, performance, and durability through targeted repair and preservation techniques. We work across all types of marine infrastructure, from jetties and wharfs to locks and sea walls, using materials and methods adapted to each asset’s condition and environment.

FAQ about the repair and preservation of marine structures
Yes. We use specialized access methods, like barges or suspended platforms, to work around tides and live port activity.
We combine surface cleaning, inhibitor treatments cathodic protection and full augmentation depending on the asset and exposure level.
Yes. It’s particularly effective in splash zones or for slab overlays exposed to chlorides.
