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 four structures St. Peter’s Bridge, Staplehill underpass, Riverside Viaduct and Pumphouse Bridge provide main routes into Burton town centre carrying on average 24,000 vehicles a day each. Vital strengthening works were required on all structures, meaning HGVs could continue to access the town and ensure that all bridges, which form vital links through Burton will be free of unplanned and disruptive maintenance work in the future.
The scope of USL Ekspan’s works included removal of the existing waterproofing systems across all decks and the supply and application of 3600m² PmB spray applied polyurethane waterproofing membrane to meet the requirements for a high specification waterproofing system and protect the structures for many years to come.
New expansion joints were required to replace the original joints with modern equivalents too allow for sections of the deck to move without affecting the road surfacing, preventing water leaking onto the bearings beneath. The solution was to use BP1 & BP3 buried joints and Britflex BEJ 5 expansion joint systems to accommodate 20mm and 50mm of horizontal movement respectively.
