A waterstop ring provides a flexible joint connection between a pipe and a concrete structure. The waterstop ring includes an annular waterstop member projecting from an outer circumference thereof, and a pair of annular shoulder portions respectively disposed on each side of the waterstop member. The waterstop member and each of the shoulder portions each include hollow annular cavities defined therein, such that when the waterstop ring is installed in a connection between a concrete structure and a pipe, and partially embedded within the concrete structure, the annular cavities allow deformation of the waterstop ring and thereby allow tilting movement of the pipe in a direction away from the central axis of the pipe.
