Leverage UCC

UCC specializes in providing underwater services to a diverse customer base. With over 50 years of history behind us, we are one of the most experienced commercial diving contractors in the world.

  • the first recorded nuclear dive;

  • the first safety-related weld repair inside a nuclear reactor vessel;
  • the first to develop and use hand-held underwater plasma arc cutting;
  • the first dry-box tig weld repair; and
  • the first major underwater rehab of a large marine aquarium.

UCC strives to provide innovative, high-quality, cost-effective services that are consistent with our commitment to the safety of our employees and those of our clients.

UCC Is A World Leader In:

  • Leak Detection

  • Reactor Vessel Weld Repairs

  • Renovation

  • New Construction

  • Underwater Plasma Cutting

The breadth of the UCC training program, for all divers, includes safety-related reactor modifications, regular updates of equipment changes, operational procedures, and advanced first-aid training. Qualifications are set to ASME standards for all position group welds in stainless steel pipe and plate in depths succeeding 45 feet.

As an annexation of our training, it is not uncommon for UCC to set up project-specific underwater mockups at remote locations. This elevates our expertise to peddle unusual installation procedures, gives us a heads-up on problem solving, and avoids expensive downtime for our clients. However, time for exacting preparation is not always available and experience alone becomes the tool of choice. When the Chicago Underground was flooded, it was Underwater Construction Corporation that was brought in to repair the massive leak. It was no time for practice. Our skill, innovation, and adaptability ensures our clients that we can get in and get the job done correctly.
