Abstract A polymer plastic contraction-expansion joint element for the aggregate decking areas of a swimming pool. The element when used as a contraction joint is comprised of an elongated generally hollow body adapted for burial in the aggregate below grade level. The body is formed of a bottom wall and parallel spaced apart upright sidewalls terminating at their upper distal ends in a open pocket including longitudinal protuberances extending along the inner face of the sidewalls. Adapted to overlie the body pocket in a removable mounting relation thereto is an imperforate polymer plastic cover having elongated skirts downwardly depending from the longitudinal side edges thereof. The skirts are insertable between the body protuberances in a springlike interfit enabling the cover to be removed and replaced as appropriate. When used as an concentration-expansion joint, the element includes a second generally hollow body mounted onto the underside of the first body for increasing the burial depth within the aggregate.
