An elastomeric sectional strip, for sealing an expansion joint on a building. Each edge of the strip is thickened for engagement in a corresponding one of a pair of grooves bordering the joint edges and is characterized by a three-point mounting of its thickened edge region inside each of said grooves. Each three point mounting is constituted by: (a) a bulge on an upper side of the edge region, in which case said bulge is located inside said groove adjacent its opening; (b) a shoulder projecting in the form of a wedge into said groove in the opposite direction to the insertion direction on an underside of said edge region, in which case after complete insertion, said shoulder bears against a corresponding stop face of the groove and (c) a camber on said upper side of said edge region close to its outer end. |
