(54) Expansion joint and method


(57) An expansion joint (20) comprises an elongated flat sheet (22) of flexible and resilient polymeric material having a width and a length; upper and lower surfaces (114, 116) and first and second edges (118, 120). The sheet has selvage edges (24, 26) and a central gland (28). The selvage edges have a pair of parallel elongate first and second scrims (132, 134) which may be formed or embedded on each of the opposite surfaces along the length of the sheet. The rough strips on each surface flank the elongated strip of bare surface of the gland (28). The sheet (22) has an array of apertures (80) located in at least one of the selvage edges (24, 26). The apertures (80) pass through the sheet and the strips and maybe of various shapes, circular, elongate, curving, and either of closed periphery or open to the edges, e.g. as slots or saw tooth edge configuration.
