Pictured at left is the experimental composite wrap and primer to be applied underwater to a deteriorated discharge port at the 73-year-old Chickamauga Lock in Chattanooga, Tenn., with the conventional steel wrap displayed at right. Forty days after the Aquawrap was installed and had endured 404 lockages, Nashville District Diver Keith Holley reported Aug. 28, 2013 that, “The material and installation condition looks the same as the day it was put in.” Divers will inspect the fiber reinforced polymer wrap periodically to monitor its durability.
