Abstract
A bar sealing apparatus includes a hollow, cylindrical intermediate end cap. The end cap has a fitting disposed within an opening. The sealing apparatus further has a hollow, cylindrical terminal end cap and a hollow, cylindrical sleeve that is configured to surround the bar. Internal threads or other fasteners of the fitting may be threaded onto the bar, and internal threads or other fasteners of the intermediate end cap and internal threads or other fasteners of the terminal end cap may be threaded onto external threads or other fasteners of the sleeve. The intermediate end cap, terminal end cap, and sleeve facilitate grout to fill a space between each of the intermediate end cap, terminal end cap, sleeve, and the bar.
