Abstract: A fire and/or water resistant expansion joint system for installation into a building joint in vertical and horizontal configurations is designed such that it can be used for either an inside or outside corner. The system comprises a core having a fire retardant infused therein. A layer of an elastomer is disposed on the core and is tooled to define a profile to facilitate the compression of the expansion joint system when installed between coplanar substrates. The system can be delivered to a job site in a pre-compressed state ready for installation into the building joint.

Abstract: A fire and/or water resistant expansion joint system for installation between substrates of a tunnel. The system includes a coating applied at a predetermined thickness to the substrates and a fire and water resistant expansion joint. The 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 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 seal includes a central portion having 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. When installed on the structure, the first flange portion is attachable to a first substrate of the structure and the second flange portion is attachable to a second substrate of the structure such that the central portion is disposed within and seals a gap formed between the first substrate and the second substrate of the structure. Movement of one or both of the first substrate and the second substrate causes a response in the central portion to maintain the seal.

Abstract: A water resistant expansion joint system includes foam, which has been formed into a desired shape by at least one of stamping, cutting, molding and die-cutting; and a layer of an elastomer disposed on the foam. The layer of the elastomer facilitates compression of the water resistant expansion joint system when installed between substrates. The desired shape of the foam includes an angle, and the water resistant expansion joint system is angled around a corner and accommodates thermal and seismic movement in the system by expanding and contracting, and creates a waterproof seal around the corner upon expansion of the foam between the substrates.

Abstract: A water resistant expansion joint system for installation into a building joint in vertical and horizontal configurations is designed such that it can be used for either an inside or outside corner. According to an aspect, the system comprises open celled foam having a water-based acrylic chemistry infused therein. A layer of an elastomer is disposed on the open celled foam and is tooled to define a profile to facilitate the compression of the expansion joint system when installed between coplanar substrates. The system is delivered to a job site in a pre-compressed state ready for installation into the building 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.
