Abstract: A fire resistant tunnel expansion joint system for installation between substrates of a tunnel. The system includes a fire protection barrier applied at a predetermined thickness to the substrates and a fire resistant tunnel expansion joint. The tunnel expansion joint includes a core and a fire retardant infused into the core. The core is configured to define a profile to facilitate the compression of the tunnel expansion joint when installed between the substrates. The fire protection barrier and the fire resistant tunnel expansion joint are each capable of withstanding exposure to a temperature of at least about 540° C. or greater for about five minutes.

Abstract: 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.

Abstract: A fire and/or water resistant expansion joint system for installation between substrates of a tunnel. The system includes a fire resistant coating applied at a predetermined thickness to achieve a substantially uniform layer on the substrates and a fire and water resistant expansion joint. The expansion joint includes a core having an edge, wherein the substantially uniform layer of the coating extends along the substrates of the tunnel to the edge of the core, and a fire retardant infused into the core. The core is configured to facilitate the compression of the expansion joint system when installed between the substrates. The coating and the fire and water resistant expansion joint are each capable of withstanding exposure to a temperature of at least about 540° C. or greater for about five minutes.

Abstract: A fire resistant and water resistant expansion joint system comprises a compressed lamination of fire retardant infused open celled foam, one coat of an elastomeric waterproofing or water resistant material on the lamination, and another coat of an intumescent material on an opposing surface of the lamination, thereby providing fire resistance in one direction and water resistance in the opposite direction. The intumescent material may be further coated with a similar elastomeric material, thereby providing fire resistance in one direction and water resistance in both directions. In the alternative, the compressed lamination may comprise first and second opposing layers of intumescent material thereon each having a respective layer of elastomeric material to provide both water resistance and fire resistance in both directions.

Abstract: An expansion joint system includes a cover plate; a spline attached to the cover plate; and a core having a fire retardant material included therein in an amount effective to pass testing mandated by UL 2079. The spline depends from the cover plate and is configured to be positioned in a gap between substrates such that the cover plate overlies the gap. The core is compressible between a first face of the spline and one of the substrates and is compressible between a second face of the spline and the other of the substrates, and the expansion joint system is configured to facilitate compression of the core when installed between the substrates by repeatedly expanding and contracting to accommodate movement of the substrates; and the core with the fire retardant material included therein is configured to pass the testing mandated by UL 2079.

Abstract: A watertight, integrated wall and roof expansion joint seal system includes an expansion joint seal for a structure. The seal includes a central portion having an underside and at least one central chamber disposed around a centerline, a first flange portion extending outwardly from the centerline and a second flange portion extending outwardly from the centerline in a direction opposite the first flange portion. The expansion joint seal includes a fold including a first fold portion and a second fold portion, wherein the first fold portion of the first flange portion is attachable to a first surface of a first substrate of the structure and the second fold portion of the first flange portion is attachable to a second surface of a the first substrate, and the first fold portion of the second flange portion is attachable to a first surface of a second substrate of the structure and the second fold portion of the second flange portion is attachable to a second surface of the second substrate, such that the central portion is disposed within and seals a gap formed between the first substrate and the second substrate of the structure. The system further includes a joint closure.

Abstract: A system configured to anchor a cover plate over an interface formed between substantially coplanar substrates includes a sleeve capable of being anchored in a first substrate; a spring located in the sleeve; a post located in communication with the spring; and a fastener secured onto the post. A head of the post is located in the sleeve, and an end of the post opposite the head of the post extends out of the sleeve to receive the fastener. The fastener is secured onto the post over the cover plate located on the first substrate such that the cover plate extends over the interface formed between the first and second substrates when they are positioned to be substantially coplanar.
