ECI on new and bespoke contracts via USL TEKSERV.
With more complex and substantial machining demands for projects, Ekspan now operate a state-of-the-art Hurco DCX3226i CNC machine, an essential addition to their in-house manufacturing facilities.
USL Ekspan is the UK's largest quality bearing supplier and installer to meet demands both in the UK and worldwide.
USL Ekspan install an extensive range of mechanical and elastomeric expansion joints and seal joints to CD358 standards.
Bridge jacking and temporary works are an essential part of most bearing replacement and refurbishment operations, ensuring works are carried out safely and efficiently without affecting the integrity of the structure.
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.
USL Ekspan has been contracted previously by Balfour Beatty in Summer 2009 to undertake waterproofing and joint works to the southbound carriageway. During these repairs, the edge of the adjacent deck on the northbound side was found to be showing similar signs of deterioration. It was decided that similar repairs were required to the northbound carriageway and USL Ekspan was asked by AOne+, the managing agent for Area 14, to provide a complete package for the deck refurbishment works, which included:
Works were planned for the school summer holidays, commencing on 15th July 2013 with completion by 22nd August 2013 under two phases, phase 1 being hard shoulder and lane one and phase 2 being lane two.
Within this period there were approximately 32 days where only one lane would be open in a southbound direction. The volume of traffic carried by the road (around 100,000 vehicles per day) meant that it was essential that works were completed on time.
Works were programmed to take place 24 hours a day, utilising lane closures between the hours of 0600 and 2000 and full road closures at night.
With the live railway below the structure and overhead line equipment energised to 25,000 volts fitted to the soffit of the centre span deck and to bridge supports, hydro-demolition was not permitted as an option for removing concrete because of the volume of water required for this type of operation, so all breaking out was to be undertaken by hand.
