A method of selecting, specifying, and inspecting polyvinyl chloride waterstop joints in concrete hydraulic structures to assure quality control under a zero-defects welded-joint concept is presented. Emphasis is placed upon basing selection of waterstop section on construction as well as design criteria. A set of quality control criteria is specified, and a special pen-knife test is described. Sample specification data are included as a means of providing the inspector with the proper tools for quality assurance.
