Commercial Diving

From processing systems to power plants, water is essential to our way of life. Harsh underwater environments deteriorate man-made structures over time and require specially trained personnel to go in the water to perform the work. Underwater mechanical structures, along with ships, bridges, dam’s and water supply systems are just a few of the structures we maintain for our clients.

Our Personnel

Chicago Underwater Divers have logged thousands of hours underwater in virtually every possible condition. They are true “tradesmen” who work underwater. Many of our personnel have backgrounds in the construction and mechanical trades which allows them to apply their top side experience underwater. Our divers have the problem-solving skills that can augment any marine project. The Dive Supervisors are experience at planning, implementation, and the performance phases of the project.
