Abstract

Sealed expansion joints comprise first and second joint members each having a backside surface adapted for installation against a planar surface. The first joint member further comprises at least one angular surface section that is designed to facilitate moisture passage thereover when installed onto an underlying wall structure. The first joint member also includes a groove disposed therein between the backside and frontside surfaces. The second joint member is positioned adjacent the first joint member, e.g., either below the first joint member or to the side of the first joint member, and includes an outwardly projecting tongue that extends towards first joint member. The tongue is disposed a desired depth into the groove. Together, the first and second joint members form a channel that extends therebetween. A sealing member is disposed within the groove and is interposed between the tongue and the groove. The sealing member is attached to the tongue to move slidably with the tongue in the groove to provide a leak-tight seal between the first and second joint members.
