EMSEAL BEJS Bridge Expansion Joint Systems NS Chezzetcook Bridge

Transitions

Factory-fabricated Upturns and Downturns

The quick and easy way to step up and down at curbs and parapet walls of bridge expansion joints.

As in all Sika Emseal expansion joint systems, continuity of seal through changes in plane and direction is an essential performance differentiator. Emseal is the first company to warrant curb and parapet wall/corner transitions to be watertight when sealed with our factory fabricated assemblies.

These single-piece 90-degree units have a 12-inch long leg and a 6-inch vertical piece on each end of the elbow.   The Universal-90’s are symmetrically coated on both sides.  This allows them to be installed as an upturn or as a downturn. Emseal’s “Universal-90’s” more reliably ensure continuity of seal and allow for much faster installation by eliminating field cutting or notching and bending at angles.

Emseal also offers BEJS Factory Fabricated Custom Transitions. These single-unit transitions are manufactured to your custom specifications regarding angle, lengths and sealant-face orientation.

What if there isn’t a curb or parapet wall and the joint just terminates at the edge of the bridge deck? In this case you’ll want to take a look at our Kickout Termination.

U.S. Patents

US Patent 9,200,437; 9,637,915

 

Custom 90’s:
US Patent 10,570,611

Universal or Custom. Transition or Termination.

Universal-90 Transitions are cut at 90-degrees with both ends open for a butt-connection to another stick or another Universal-90. Either leg can be trimmed in the field to connect to straight run material or to another Universal-90 when going, for example, up and over a curb, into a parapet, or up and down treads and risers.

Universal-90 Terminations end, on the 6-inch leg, in a 45o sealed and mitered end.  This allows termination as a stand alone upturn or provides a surface against to which a wall joint system can be married.  Flipped over, the Universal-90 termination unit can be alternatively installed as a downturn termination where a joint runs off the deck.  In this use, the sealed, mitered end provides a drip edge for drainage of water off the joint.

Custom Transitions and Terminations coated on just the weather-facing faces, are also available when field conditions and measurements are known up front. Consult EMSEAL.

Features Explained

Watertight — Like the BEJS System Universal 90’s and custom 90’s from EMSEAL are watertight and so protect rockers, bearings and the underlying bridge support piers and beams.

Non-Invasive Anchoring — There are no hard metal-to-substrate connections with Universal-90 transitions or terminations. This includes embedded pins, anchors, screws, bolts or tracks, trays or rails, flanges or coverplates. The system is locked to the joint faces by means of the backpressure of the foam, epoxy in some cases, and the injected sealant bands at the joint face.

Versatility — Universal-90’s are coated on both sides (regardless of the single or dual coating nature of the EMSEAL impregnated-foam product with which they are joined). This allows them to be sealed to any side of water contact when turned in any 90-degree position. All Universal-90 pieces can function as an inside or outside corner.

Joint-Size Variation —Uniform bellows appearance, and the ability to handle variations in joint size through size-switching makes the Universal-90’s aesthetically and functionally versatile.
