Latest in Joint Sealing Technology

CSC Services will be showcasing the innovative Emseal BEJS structural expansion joint system at the Bridges Conference & Exhibition. 

The BEJS System, from NCC Movement Joints Limited, is ideal for sealing the difficult structural expansion joints on bridge decks, wing walls, abutments, parapet walls and more. It brings together the benefits of several different systems into one single installation, providing a watertight, trafficable, new and retrofit bridge movement/expansion joint sealing system. 

Emseal BEJS is designed to handle harsh environmental conditions and features watertightness with greater movement capability, better low temperature flexibility and higher temperature stability than other technologies. 

Innovative BEJS System Features

  • Watertight: the tensionless silicone 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 materials is pre-compressed in the factory ensuring that the spring energy of compression is always pushing back on the substrate. 
  • Non-Invasive Anchoring: there is no drilling into sound concrete and no hard metal-to-concrete connections, as required in systems with mechanical fixings such as embedded pins, anchors, screws. bolts or tracks, etc/ Instead, the BEJS System is licked into the joint faces by means of i) backpressure of the foam, ii) bonded by the epoxy adhesive, iii) the injected silicone band at the foam and silicone bellows joint interface. 
  • Continuity of Seal: continuity of seal through changes in plane and direction is a real performance differentiator of the Emseal BEJS System. Prefabricated details and sections are provided to ensure watertight transitions from deck to walls, at kerbs, pavements and crossovers, etc. 
  • Versatility: The BEJS System is resistant to fuels and other automotive fuels, plus the system can easily accommodate variations in joint dimensions, particularly variable joint widths without excessive, expensive and time consuming additional preparatory works.
  • Installation: fast, easy installation can also be staged to preserve partial traffic flow. Under normal conditions and temperatures, the BEJS System provides a driveable surface within hours of installation.
