Application

  • Watertight, traffic durable, joint-face-adhered, precompressed, primary seal for retrofit and new expansion joints in road bridges, wing walls, abutments, jersey barriers, longitudinal joints, precast panels, etc.
  • Suitable for new construction and retrofit bridge preservation of old or failed joint Systems in concrete or rebuilt joint edges. Use in embedded metal angles where demolition or removal of the metal angles is not feasible and where existing joint opening is suited to the movement capability of BEJS.
  • Suitable for lasting replacement of failed caulk joints.

Description

The BEJS System (Bridge Expansion Joint System) is comprised of a precompressed, silicone-and-foam hybrid installed into field-applied epoxy adhesive on the joint faces; with the silicone bellows locked to the joint faces with a silicone sealant band.


The BEJS System features an innovation in sealant technology in the form of a microsphere-modified, 100% acrylic impregnation infused into the cellular foam base material.


The material is odorless, clean handling, UV stable, non-staining, and features low temperature flexibility not previously available in asphalt, wax, or isobutylene-based predecessors or competitors. The result is extension of the usability of the product to applications where asphalt and wax-based predecessors did not work well under conditions of thermal shock (rapid opening and closing of joints during large temperature swings). These applications include joint-face adhered installations on bridge decks, wing walls, abutments, jersey barriers, precast panels, etc.

Suitability is further extended to applications in colder geographical regions to which asphalt and wax-based predecessors have not previously been recommended.


Features and benefits:

  • Watertight – the tensionless silicone bellows are installed just below the deck surface. This ensures watertightness is achieved at the deck surface.
  • Non-Invasive Anchoring – there are no hard metal-to-concrete connections with the BEJS System. This includes embedded pins, anchors, screws, bolts or tracks, trays or rails. The System is locked to the joint faces by means of the backpressure of the foam; the epoxy adhesive; and the injected silicone sealant band at the joint face to foam and silicone bellows interface.
  • Continuity of Seal – as in all Emseal expansion joint Systems, continuity of seal through changes in plane and direction is an essential performance differentiator. 'Universal 90s“ Kick-out Terminations' and 'Custom Transitions' are factory fabricated transition pieces from Emseal that can be installed at inside corners and outside corners as needed and are warranted by Emseal to be watertight through the entire movement capability of the product. Alternatively, details for field-fabricated transitions from deck to wall, at curbs, sidewalks, parapets, tees, and crosses are available from Emseal.
  • Movement capability: +60% and -60% (Total 120%) of nominal material size.
