A mid-rise hotel building was five years old when widespread water leakage was discovered through its exterior insulation finish system (EIFS) façade. During the assessment it was discovered that the EIFS attachment to the exterior gypsum wallboard substrate had been compromised by the water infiltration. The decision was made to mechanically fasten the existing lamina to the metal stud backup and install a new lamina over the existing lamina. This paper describes processes used in assessing the cause and extent of the problem and the innovations developed for the repair process.
