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.

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.
