1. A fire and water resistant expansion joint system, comprising:
- a core;
a fire retardant infused into the core; and
a water resistant layer disposed on the core;
wherein the layer is tooled to define a profile to facilitate compression of the expansion joint system when installed between substrates, wherein the core infused with the fire retardant compressed has as a density of about 160 kg/m3 to about 800 kg/m3; and
wherein the expansion joint system is angled around a corner, and the fire and water resistant expansion joint system and the core infused with the fire retardant are configured to pass testing mandated by UL 2079.

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.

26. A fire and water resistant vertical expansion joint system, comprising:
-
a first section of core extending in a horizontal plane; a second section of core extending in a vertical plane; an insert piece of core located between the first section of core extending in the horizontal plane and the second section of core extending in the vertical plane, the insert piece being configured to transition the first section of the core from the horizontal plane to the vertical plane of the second section of the core; and a water resistant layer disposed on the core, the water resistant layer imparting a substantially waterproof property to the core, wherein the water resistant layer is a continuous layer of the water resistant layer from the vertical plane to the horizontal plane and the water resistant layer is a continuous layer of the water resistant layer over the insert piece, and the insert piece is held in place by the continuous layer of the water resistant layer, and the expansion joint system is configured to accommodate at least one of thermal and seismic movement in the system; wherein the core is infused with a fire retardant; wherein the fire and water resistant vertical expansion joint system is installable between horizontal substrates and vertical substrates, wherein the core infused with the fire retardant compressed has as a density of about 160 kg/m3 to about 800 kg/m3; and wherein the fire and water resistant vertical expansion joint system and the core infused with the fire retardant are configured to pass movement cycling and fire endurance testing mandated by UL 2079. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35)
