The DH Hill Library Tower North Face, the DH Hill Library Tower South Face, and Poe Hall Exterior were experiencing waterproofing and leaking issues at expansion joints, control joints, windows, doors, masonry-to-masonry joints, and masonry-to-metal joint. The project scope involved the removal of all existing caulking and backer rods from these interfaces, cleaning all surfaces of dirt, paint, and oils, prime all joints, sealing all interfaces, re-caulking all interfaces, resealing all joints and seams, and repointing masonry where necessary.
