1. A waterstop joint comprising:
a sealing strip made of an elastomer;
two bulged portions, each of the two bulged portions extending along a different one of two peripheries of the sealing strip;
two fixation strips, each of the two fixation strips extending from a different one of said two bulged portions, and extending in a same plane as the sealing strip;
a multitude of injection tubes for injecting a curing liquid, such as epoxy resin, wherein one outer end of each of said injection tubes is mounted to, or is adjacent to, one of the two fixation strips;
wherein the outer end of each of said injection tubes is mounted to, or immediately adjacent to, one of said two bulged portions; and
wherein the two bulged portions comprise a compressible portion on outward facing sides of the two bulged portions, as viewed from a center of the waterstop joint, the compressible portion is made of a material that is more easily compressible than the elastomer of the sealing strip, and the outer end of each of said injection tubes is mounted to, or immediately adjacent to, said compressible portion.
