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 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 therein. A layer of a water resistant material is disposed on the core to facilitate the compression of the expansion joint system when installed between substrates. The system can be delivered to a job site in a pre-compressed state ready for installation into the building joint.

Abstract: An expansion joint system includes a cover plate; a spline attached to the cover plate; and foam 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 foam is compressible between a first face of the spline and one of the substrates and the foam 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 foam when installed between the substrates by repeatedly expanding and contracting to accommodate movement of the substrates; and the foam with the fire retardant material included therein is configured to pass the testing mandated by UL 2079.

Abstract: A fire and water resistant expansion and seismic joint system has a cover plate; a spline attached to the cover plate along a first edge of the spline; and a core comprising a first core portion and a second core portion, each portion being located on an opposing face of the spline. The first core portion and the second core portion have a fire-retardant material infused therein. The spline depends from the cover plate in a one piece construction and extends into the core to a depth within the core, and is positioned in a gap between substantially coplanar substrates such that the cover plate overlies the gap. Each portion of the core is compressed between a respective face of the spline and a face of one of the coplanar substrates.

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: 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.
