Most joints, and some cracks in concrete structures, require sealing against the adverse effects of environmental and service conditions. This report is a guide to better understanding of the properties of joint sealants and to where and how they are used in present practice. Described and illustrated are: the functioning of joint sealants; required proper-ties, available materials and applicable specifications for field-molded sealants and pre-formed sealants such as waterstops, gaskets or compression seals; determination of joint movements, widths, and depths; outline details of joints and sealants used in general structures, fluid containers and pavements; methods and equipment for sealant installation including preparatory work; performance of sealants; and methods of repairing defective work or maintenance resealing. Finally, improvements needed to insure better joint sealing in the future are indicated.
