Waterstops are grouped into six categories, depending on shape and material. Studies have indicated that a properly compounded polyvinyl chloride is likely to outlast many of the materials used in the past. An investigation of the watertightness of various shapes and sizes of waterstops is described, from which it is concluded that "flat corrugated" and "flexible metal" types are superior to "dumbbell" and "metal plate" waterstops. Physical properties of waterstops are discussed with reference to their ability to withstand rough treatment during installation and their ability to accommodate joint movements. Waterstops of various shapes and materials are compared with regard to ease of installation. Methods developed for cutting, splicing, and installation of pvc waterstops are outlined.
