Repair, Evaluation, Maintenance, and Rehabilitation Research Program. Repair of Waterstop Failures: Case Histories

J. E. McDonald

Nearly every concrete structure has joints that must be sealed to ensure its integrity and serviceability. This is particularly true for for monolith joints in hydraulic structures such as concrete dams and navigation locks. Embedded waterstops are generally used to prevent water passage through the monolith joints of such structures. A waterstop failure can result in various problems ranging from minor leakage with cosmetic concern to significant hydraulic forces and structural overloading which could threaten the stability of a structure. The primary objective of this study was to identify materials and techniques which have been used in repair of waterstop failures. Also, based on a review and evaluation of current practices, a secondary objective was to identify those areas where research is needed to supplement existing technology.
