An expansion joint sealing system includes 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.

Expansion joint sealing system having shielding properties

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&#xb0; C. or greater for about five minutes.

Fire resistant expansion joint systems

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&#xb0; C. or greater for about five minutes.

Water and/or fire resistant tunnel expansion joint systems

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.

Water and/or fire resistant expansion joint system

An expansion joint system includes: a core; and water resistant coating on the core. The core and the water resistant coating forming an elongated section, the elongated section configured to be oriented between substrates. The expansion joint system further includes a termination section located at one end of the elongated section and comprising a flared end forming an angle with the elongated section and configured to direct fluid and/or particles and/or solvents away from the expansion joint system.

Expansion joint system

Fire resistant tunnel expansion joint systems

An expansion joint system includes: a core; and a layer of an elastomer disposed on the core. The core and the layer of elastomer disposed thereon form an elongated section, the elongated section configured to be oriented vertically between substantially coplanar substrates. The expansion joint system further includes a termination section located at one end of the elongated section and comprising a flared end forming an angle with the elongated section and configured to direct fluid and/or particles and/or solvents away from the expansion joint system.

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.

Movement-compensating plate anchor

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&#xb0; C. or greater for about five minutes.
