A waterstop repair method and structure for use in both new and existing concrete structures in which a reinforced neoprene diaphragm is anchored to the concrete structure using corrosion-resistant anchors, fiberglass hold-down strips and polyester felt adhesive strips saturated with epoxy adhesive.

A waterstop repair method and structure for use in both new and existing concrete structures in which a reinforced neoprene diaphragm is anchored to the concrete structure using corrosion-resistant anchors, fiberglass hold-down strips and polyester felt adhesive strips saturated with epoxy adhesive. The diaphragm is supported by a pressure injected hydrophylic urethane foam which is pumped beneath the diaphragm which thereby provides support for the diaphragm and fills the interstices of the existing concrete joint to prevent water leakage in and around a failed waterstop and to thereby form an integral, water-tight structure for new and existing concrete joints.

A water-sealed joint defined between a pair of structural elements comprising: a flexible diaphragm member having side edges disposed on respective surfaces of said pair of structural elements in covering relationship to said joint such that a center portion of said diaphragm member, between said side edges thereof, defines therebelow a region in communication with said joint; anchor means for anchoring said side edges of said diaphragm member to said respective surfaces of said structural elements laterally of said joint; an access opening defined by at least one of said structural elements, said opening intersecting said joint at a location below said region defined by said center portion of said diaphragm member and extending from said location to another location on said respective surface of said at least one structural element laterally of said anchor means; a water sealant collectively filling said joint, said region defined below said center portion of said diaphragm member, and said access opening, whereby said joint is water sealed. A method of water-sealing a selected portion of a joint defined between a pair of structural members comprising the steps of: (a) laying a flexible diaphragm member on respective surfaces of said structural members so that said diaphragm covers said selected joint portion, and such that a center portion of said diaphragm member establishes therebelow a region in communication with said covered selected joint portion; (b) anchoring at least side edges of said diaphragm member to said respective surfaces of said structural members; (c) forming at least one access opening in one of said structural members which intersects said joint at a location below said region established by said center portion of said diaphragm member and extends therefrom to a location on said respective surface of said one structural member laterally of said joint; and then (d) injecting a foamable water sealant into said at least one access opening and allowing said sealant to foam sufficiently to fill said selected joint portion and said region established below said center portion of said diaphragm member, whereby said selected joint portion is water-sealed.
