CHICAGO, IL – Work continues at the Shrine. This week was finishing up the bond beam installation on the south wall at the parapet. 24” threaded stainless steel rods were set vertically through the new bond beam and brick and connected into the existing brick. Rebar was set horizontally and the bond beam was grouted solid. The bond beam was installed to fortify and strengthen the wall. When the old steel is removed the wall needs to have the strength to stand on its own until the new steel is set in place.
