Watertight movement joint system for bridge deck joints. parapet & wing joints etc.
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.
