Underwater construction work

Underwater construction requires specialised expertise and precise technical knowledge. The personnel of Unwa Oy have taken part in numerous underwater construction projects where achieving a high-quality end result has always required a professional diving team. In underwater operations, it is particularly important that all equipment is properly maintained and inspected on schedule in accordance with regulations.

Our divers have been involved in, among other tasks, erosion casting and element installations for harbour piers. We have also carried out various concrete repair works at several hydropower plants.

Traditional concrete repair work includes, for example, concrete encasements and pressure grouting. Underwater and waterline concrete structures are exposed to heavy stress due to Finland’s varying summer and winter conditions. It is crucial to perform regular inspections and repairs to ensure the long-term durability of these structures.

Underwater construction always requires careful planning and precise execution. Safe equipment and experienced personnel guarantee successful results even in the most demanding projects.
