Underwater Services for Utility and Infrastructure Projects

Specialized Commercial Diving, Welding & Confined Space Work

      Glenn Industrial Group delivers precision-engineered underwater services for the world’s most demanding infrastructure environments. Our ADCI-certified dive teams specialize in subaqueous inspection, welding, seal repair, and confined entry operations — all backed by 29+ years of experience in civil, power, and industrial sectors.

      Glenn’s Commercial Diving Services Deliver Safe, Subaqueous Infrastructure Solutions

      We offer a full range of diver-delivered and ROV-assisted underwater solutions that support construction, maintenance, and emergency response efforts.

      Our certified divers perform detailed structural inspections of underwater assets, identifying damage, corrosion, or wear. We also provide precision repairs, restoring structural integrity to bridges, piers, dams, and marine facilities.

      Using advanced welding and cutting techniques, we deliver high-strength, permanent underwater repairs. Our skilled divers handle complex metallurgical tasks in low-visibility, high-pressure environments.

      From sunken vessels to storm debris, our crews safely locate, document, and recover submerged materials. We offer fast-response salvage services with environmental safeguards and specialized lift equipment.

      We specialize in underwater leak detection, sealing, and long-term pipeline rehabilitation. Our solutions extend service life, restore flow efficiency, and prevent costly environmental impacts.

      OSHA-compliant entry into vaults, turbines, and tank environments with redundant safety systems

      Diver-based and ROV-assisted surveys of submerged intakes, pipelines, and discharge tunnels.

      Isolation, removal, and resealing of underwater gate systems on dams, plants, and industrial sites.

      High-volume removal of silt, sludge, or debris from tanks, clarifiers, and wet wells.

      Epoxy injection, coatings, form-and-pour concrete, and steel patching for underwater infrastructure..

      Industries That Rely on Our Underwater Services

      Glenn Industrial Group’s underwater teams support a wide range of utility and industrial sectors where reliability, uptime, and safety are non-negotiable.

        • Hydroelectric Dams & Spillways
        • Nuclear & Fossil Power Plants
        • Municipal Water & Wastewater Utilities
        • Ports, Canals, and Navigation Structures
        • Intake and Outfall Infrastructure

        Our Commitment to Safe, Certified Commercial Diving Operations

        Every dive is executed under rigorous safety protocols, tailored to the environment and regulatory requirements. Glenn’s crews are certified in confined space entry, hazmat procedures, and work under standards set by:

        Integrated Underwater Tools Enhance Safety, Accuracy, and Inspection Efficiency

        At Glenn Industrial Group, our dive teams are reinforced with advanced surface and sub-surface technologies that deliver real-time data, improve safety, and eliminate guesswork. This integration of tools is critical in confined, low-visibility, or high-risk underwater environments.

        Sonar Imaging

        High-resolution multibeam and scanning sonar provides visibility in turbid or zero-visibility water, enabling precision alignment, object detection, and sediment mapping

        Topside Diver Communications

        Hardwired and wireless systems ensure constant communication between divers and surface supervisors, enhancing coordination and emergency response.

        ROV-Diver Coordination

        Remotely operated vehicles (ROVs) are deployed for pre-dive reconnaissance, diver tracking, and support in inaccessible or hazardous zones.
