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.

Recent failures of rubber waterstop have occurred in a floodwall in which the web of the waterstop has been ruptured by differential movement of adjacent concrete monoliths. The investigation described in the report was conducted to study the effects of various joint conditions on rubber waterstops and to develop joint treatment methods that would eliminate or minimize damage to the waterstop.
