Professor P.V. Vijay, West Virginia University, mixes primer that divers will apply prior to installing an experimental Fiber Reinforced Polymer composite wrap underwater on a deteriorated discharge port at the 73-year-old Chickamauga Lock in Chattanooga, Tenn. Observing in background from left are divers Chris Clabough and Brandon Kennedy (hidden behind Clabough); Bernie Schulte, Nashville District Design Branch engineer, and Britt Henderson, civil engineer (hidden by Vijay). 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 Aquawrap periodically to monitor its durability.
