An expansion joint includes a foam strip having first and second lateral side surfaces extending axially outward to an outer edge surface, and an elongated gasket having a laterally expandable portion adhered to the outer edge surface of the foam strip, with the laterally expandable portion extending between first and second lateral end portions. The first and second lateral end portions each define at least one of a laterally outward facing bonding surface and an axially inward facing bonding surface, with the at least one bonding surface being spaced apart axially outward from the corresponding one of the first and second lateral side surfaces of the foam strip.

An expansion joint design for supporting transfer loads. The system includes an elongated core and at least one longitudinal load-transfer member which are bonded together.

A system which creates a durable seal between adjacent horizontal panels, including those that may be curved or subject to temperature expansion and contraction or mechanical shear. The durable seal system incorporates a plurality of ribs, a flexible member between the cover plate and the ribs and may incorporate a load transfer plate to provide support to the rib from below, and/or cores of differing compressibilities.

An illustrative example method of making a concrete expansion joint insert includes establishing an insert body having two ends, two longitudinal edges between the ends, and two side surfaces between the longitudinal edges and the ends. A sealant is secured to one of the longitudinal edges so that the insert and the sealant can be simultaneously inserted into an expansion joints.

An expansion joint seal system with a water-activated impregnation solute, and a body of an open-celled and resiliently-compressible foam, where the volume of the water-activated impregnation solute may be combined on-site and on-demand with water and manually impregnated into the body of the foam for insertion.

A concrete slab joint forming system and method for forming a joint between adjacent concrete slabs. In various embodiments, the concrete slab joint forming system includes a concrete slab joint former, an extension connector, a cross intersection connector, a tee intersection connector, an end connector, a field cut connector, and/or any combination of any quantity of these components.

An illustrative example embodiment of an assembly for making a concrete expansion joint insert includes an extruder a device that receives material from the extruder. The device includes a flow path through the device and at least one internal feature that directs the material away from a middle of the flow path and toward outside edges of the flow path to establish an approximately equal flow rate of the material through the middle and outside edges of the flow path.

An expansion joint seal system with a water-activated impregnation solute, and a body of an open-celled and resiliently-compressible foam, where the volume of the water-activated impregnation solute may be combined on-site and on-demand with water and manually impregnated into the body of the foam for insertion.

An expansion joint sealing system comprises a core body having an EMP, EMI, RFI, electronic surveillance and/or EMR shielding/barrier material introduced in the core body as at least one of a component or layer, disposed on the core body as a coating or wrapping, or disposed beneath the core body. The core body with the shielding/barrier material is configured to expand and contract when compressed between substrates forming an expansion joint to accommodate movement of the substrates and maintain a seal of the expansion joint.
