Elastomeric Bridge Expansion Joint

AssaFlex RE is a durable and versatile expansion joint system with unique properties such as puncture resistance, flexible and waterproof with 8 No standard models designed to accommodate movements of up to 150mm.The combined compound of RSS1, standard PBR with inner steel sheets, forms a formidable membrane with plenty of flexibility to withstand plenty of pressure and movement. The steel is shut blasted and laser cut to form high quality steel components for bonding and installation.


AssaFlex Expansion Joint comes in nine different types; AssaFlex 280 - AssaFlex 1100. The membrane is produced in a variety of widths and lengths to suit different types of joints. In some cases the length of the membrane can be changed to the requirements of the client, depending on circumstances
