Bridge Expansion Joint System, BEJS is a traffic-durable bridge and roadway expansion joint which provides a primary watertight seal. It is designed to handle harsh environmental conditions and features greater movement capability, better low temperature flexibility and higher temperature stability than other technologies. Non-invasive anchoring provides for quick turnaround and repairs. The BEJS System helps prevent and/or decrease maintenance costs to bridge bearing pads and support structures. Primarily designed for D.O.T./Infrastructure markets, it is ideal for new construction and retrofit of old or failed bridge expansion joint systems in: Concrete-to-concrete substrates / Rebuilt joint faces / Where demolition and removal of existing embedded metal angles is not feasible or affordable / As a lasting replacement for all failed liquid-sealant joints in parapets, sidewalks, jersey-barriers, etc.

The 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 a hydrophobic acrylic impregnation infused into the cellular foam base material resulting in low-temperature flexibility not available in asphalt, wax, or isobutylene-based products.

Available on reels for smaller gap widths (1/2″ – 1 1/4″ / 12mm – 30mm) or a sticks for larger gap widths (1 1/2″ – 4″ / 35mm – 100mm).

Watertight—the tensionless silicone bellows is installed just below the deck surface. This ensures watertightness is achieved at the deck surface.

Unlike liquid-applied sealants, compression seals, and inflated seals, the BEJS System does not rely on adhesion in tension. Instead the material is precompressed in the factory ensuring that the spring energy of compression is always pushing back on the substrate.

BEJS is not like other foam-based (EVA) expansion joints. BEJS is supplied precompressed to less than the joint size. It is held in compression by its packaging. When released it expands. BEJS, properly sized, is never in tension in the joint. This is the key to its performance.

BEJS is coated at a width that exceeds the maximum expected joint opening. Expansion is faster when hot and slower when cold.

Non-Invasive Anchoring—there are no hard metal-to-concrete connections as those found in systems with embedded pins, anchors, screws, bolts or tracks, trays or rails. Instead, BEJS is locked to the joint faces by means of the 1) backpressure of the foam; 2) the epoxy adhesive; and 3) the injected silicone sealant band at the joint face to foam and silicone bellows interface.
