An expansion joint seal for partial imposition in a joint extending in a longitudinal direction and having a first substrate and a second substrate, the first substrate and the second substrate being substantially co-planar with a first plane, the first substrate being distant the second substrate by a first distance the first substrate having a first substrate thickness and a first substrate end face substantially perpendicular to the first plane, the second substrate having a second substrate thickness and a second substrate end face substantially perpendicular to the first plane, the expansion joint seal comprising: a cover plate having a cover plate length extending, in use, in the direction of the joint, and a plurality of ribs, each of the plurality of ribs having a rib dimension extending in the direction of the cover plate's length, characterised in that it further comprises a body of a resilient compressible foam sealant having a foam body length extending in the direction of the cover plate's length, a foam body bottom surface, a foam body top surface, and an uncompressed foam body width, each of the plurality of ribs piercing the body of a resilient compressible foam sealant at the foam body top surface, each of the plurality of ribs not extending to the foam body bottom surface, a connecting member attached to the cover plate and to each of the plurality of ribs, the connecting member being a pivot joint such as a conventional hinge or such as a flexible connector, such that each of the plurality of ribs remains rotatable in relation to the cover plate, the cover plate length and the foam body length being equivalent; the sum of said rib dimensions of the plurality of ribs being not more than one half the cover plate length, and the body of a resilient compressible foam sealant contacting the first substrate end face rand the second substrate end face when imposed under compression between the first substrate and the second substrate, the uncompressed foam body width being greater than the first distance. a cover plate having a cover plate length extending, in use, in the direction of the joint, and a plurality of ribs, each of the plurality of ribs having a rib dimension extending in the direction of the cover plate's length, characterised in that it further comprises a body of a resilient compressible foam sealant having a foam body length extending in the direction of the cover plate's length, a foam body bottom surface, a foam body top surface, and an uncompressed foam body width, each of the plurality of ribs piercing the body of a resilient compressible foam sealant at the foam body top surface, each of the plurality of ribs not extending to the foam body bottom surface, a connecting member attached to the cover plate and to each of the plurality of ribs, the connecting member being a pivot joint such as a conventional hinge or such as a flexible connector, such that each of the plurality of ribs remains rotatable in relation to the cover plate, the cover plate length and the foam body length being equivalent; the sum of said rib dimensions of the plurality of ribs being not more than one half the cover plate length, and the body of a resilient compressible foam sealant contacting the first substrate end face rand the second substrate end face when imposed under compression between the first substrate and the second substrate, the uncompressed foam body width being greater than the first distance.
