The importance of carrying out bearing and expansion joint inspections by proficient and competent engineers who understand their functionality can often be key to maximising a structure’s lifespan and avoiding major, unexpected, emergency repair costs.
USL Ekspan have carried out a number of projects for swing bridges and foot bridges. From design, fabrication of all structural components, to trial erection and final installation. Details of these type of bridge installations can be supplied on request.
The brief included the removal of the existing joints at each abutment and their replacement with a suitable proprietary bridge expansion joint system.
The expansion joint gap was expected to open at its maximum of 85mm and it was considered that the most suitable method of repair was to remove the existing system and install a Britflex BEJ bridge expansion joint.
The Britflex BEJ joint was selected as it allows for movements between a minimum gap setting of 30mm and a maximum of 85mm.
The replacement of the joint system was undertaken during one day using multiple crews working within lane closures to provide access to each half of the joint at a time.
