Abstract: Water leakage through and around failed waterstops in concrete structures can cause serious flooding, damage to equipment, affect structural stability, and pose potential safety problems. Techniques have been developed to replace damaged waterstops by installing drill holes along monolith joints and filling with chemical grout systems. New developments include the use of bonded and unbonded liners and advanced chemical grout materials.
