This armor plate will utilize post installed anchorage into the existing concrete and grout backfill. The repair work required for the horizontal wall armor involves removal of existing concrete, to provide a recess for post-installed reinforcing, and a welded connection for approximately 10 feet of horizontal wall armor with a grout backfill. This work is anticipated to be done during the 2026 Navigation Lock outage. Access will be from the navigation lock deck by approved means of lowering workers and materials.
