CATHODIC

Kings Bay Naval Submarine Base, GA

PROJECT DETAILS

This project involved comprehensive repairs to the concrete caissons at the Kings Bay Submarine Base in Georgia. The work entailed pressure washing the caissons to eliminate marine growth and disposing of all debris off-site. Spall repairs were performed on approximately 90 square feet of concrete using non-shrink cementitious grout/mortar. Additionally, cracks were prepared and sealed with high-pressure epoxy grout for about 3,313 linear feet of caisson surfaces, both inside and outside, as well as on the deck surface. The project included blasting and coating two tide gauges with epoxy paint, inspecting and reinstalling the caisson rubber seals, and installing missing Monel steel studs on both vertical sides and the bottom of the caisson. Concrete was chipped away at the bottom of the caisson base to a depth of approximately 12 inches, followed by the installation of six 8′ x 2.5′ stainless steel bearing plates with studs and forming and placing concrete to incorporate those bearing plates.

Furthermore, four caisson deck hatch covers were replaced, and ladders were installed inside the caisson. Anodes were also installed for cathodic protection of the ladders, mechanical piping, and handrails. Overall, the project aimed to ensure the structural integrity and longevity of the caissons, enhancing safety and functionality at the submarine base.
