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. <EOS>
