Abstract

A gasket for concrete structures such as tunnel segments includes a gasket body having a bottom face configured to be positioned against a surface of an associated tunnel segment. The bottom face may include a set of spaced indentations. First and second anchor members protrude from opposed side edges of the gasket adjacent the bottom face of the gasket. The anchor members are configured to attach the gasket to the tunnel segment during casting of a precast concrete member. The gasket body forms a groove in the concrete member and the anchor members form side channels in the groove. A respective fin can be provided on opposed side faces of the gasket. Should a defect be found in the original gasket, the gasket body can be removed from the groove of the concrete member relatively easily, even in the field, and a replacement gasket having corresponding anchor members, fins and indentations, can be snapped into the groove.
