An assembly for sealing the intersection of curb and gutter portions of adjacent roadway slabs, including side pads joined by an upstanding joint membrane and a sealing flap extending away from them. The sealing flap is more flexible than the joint membrane, but has a relatively rigid zone positioned to promote folding of the flap between the side pads and below the joint membrane when the side pads are secured to the curb portions. The folding takes place without bunching and wrinkling to provide a smooth and neat transition from the curb to the gutter portions to promote effective sealing. A method of installing that assembly is also disclosed. Further, an assembly for sealing the gap between curb and sidewalk portions is disclosed, in which a flexible sealing flap extends from the upper ends of side pads joined by a flexible joint membrane and in which the highly flexible sealing flap is folded and reverse folded to provide a convolution adapted to be sealingly secured to a sidewalk end dam section, with the regions of the flap at the intersection of the curb and gutter portions forming a V-shaped configuration which merges with the convolution and with the joint membrane without wrinkling or bunching.
