The Castle Group offers services and expertise across a wide spectrum of underwater engineering and construction needs, including complete bridge design and installation.
Bulkhead & Pier Rehabilitation & Construction
We can implement innovative designs that use steel, timber, concrete, or composite materials. From repairs to replacements, we have extensive experience working on both large-scale public projects as well as smaller projects for private owners. Our clients’ designs and materials are customized to suit their specific requirements — there is no “one-size-fits-all” approach. Our bulkheads and piers are designed and built to withstand the wear-and-tear we know they will take, meaning our clients get the benefits of our work for years to come.

Submarine Power Cable Recovery and Repair
We provide a staffed and fully equipped barge capable of locating, uncovering, and lifting cable from under the channel bottom to the barge surface. This enables the most cost-effective way for utilities to perform repairs. We then set and rebury the cable to the required depth once repairs have occurred.

These installations can be critical to repairing foundation failures, improving tower foundation stability, and creating specialized tieback systems.
