Maintaining, Repairing & Protecting Underwater Assets

There currently exists in Canada, a vast inventory of public and privately owned underwater infrastructure, and some of these structures have been around almost since confederation. All these assets require periodic maintenance to ensure their safety and to extend their useful lifespan.

Some of the underwater maintenance and repair projects we regularly take on include the cleaning and removal of zebra mussels from water intake screens, installation of zebra mussel prevention systems, concrete crack injection and repairs, valve replacements, bridge pile rehabilitation, dredging of sediment and debris removal, scour repair and prevention, underwater pipeline location and depth of cover surveys, floating silt curtains and turbidity barriers, and protection of underwater pipelines, and that’s just barely scratching the surface!
