The Emseal BEJS SYSTEM builds on a track record of over 30 years of sealing bridge joints with precompressed, impregnated foam sealants.
The system is comprised of a precompressed, silicone impregnated foam hybrid installed with a field-applied epoxy adhesive on the joint faces and sealed with Pecora silicone.
BEJS can be used for:
Watertight: The tensionless silicone bellows is installed just below the deck surface. This ensures watertightness is achieved at the deck surface.
Compression: 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.
Non-Invasive Anchoring: there are no hard metal-to-concrete connections in the 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 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.
Continuity of Seal: as in all EMSEAL expansion joint systems, continuity of seal through changes in plane and direction is an essential performance differentiator. Details for watertight, field-fabricated transitions from deck to wall, at curbs, sidewalks, parapets, tees, and crosses are available with the BEJS SYSTEM.
Aesthetics & Versatility: Standard bellows colour is black; with grey also readily available (other custom colours can be discussed with Allco), uniform bellows appearance, fuel resistance, and an enhanced ability to handle variations in joint size are among other system features.
Installation: Fast, easy and can be staged to preserve partial traffic flow.
The removal and replacement of the existing mechanically fixed metal plate system with a more permanent and safer watertight system less likely to vibrate loose as a result of continuous thermal, mechanical and seismic movement.The existing system was more difficult to install and suffered recurring problems with mechanical fixings which...READ MORE
In April 2012 the Bridge Nosing’s were replaced on the Temuka Bridge which is located just out of Timaru. After a short time the nosing began to crack and fail. In March 2016 Downers Timaru, on behalf of NZTA, undertook the job of replacing all of the Bridge nosing’s using Emseal Emcrete and the...READ MORE
