An improved prestressed concrete tank having a core wall comprising elongated panels of precast concrete assembled in spaced, side-by-side relationship. The panels having on their outer faces a sheet of metal presenting parallel longitudinal undercut channels and a lateral flange extending parallel with the elongated sides of the panels and laterally outwardly therefrom. The sheet metal flange has a lip on the outermost edge which extends from the tank in a direction substantially perpendicular to the panel. The flange lips of adjacent panels are spaced from one another. A sheet metal, channel shaped splice member is interposed in the space between the flange lips of adjacent panels, the splice member having upstanding sides which abut the flange lips of adjacent panels and the flange lip and the abutting upstanding side being seamed together in a tight fold, thereby locking adjacent precast concrete panels together with a watertight seam. |
