Extensive repairs underway on A500 Campbell Road
VolkerLaser has been appointed by National Highways to deliver major refurbishment works to the A500 Campbell Road in Stoke-on-Trent, aimed at enhancing the long-term durability and performance of the structure.
The full scope of works includes the installation of temporary works, removal and replacement of surfacing and waterproofing systems, bridge deck surveys, concrete repairs, Cathodic Protection works and joint installation.
Works commenced in July 2026, with the installation of temporary works shutters to the underside soffit of the bridge deck. Since then, the team has successfully completed surface removal to both the north and south bridge decks, along with the removal of the waterproofing membrane across both decks. Comprehensive bridge deck surveys have also been undertaken, including concrete chloride sampling, low cover surveys and hammer tap surveys, providing valuable insight into the condition of the structure.
Stage one of the concrete repairs to the south deck has now been completed. This involved, concrete removal, steel reinforcement replacement and cleaning, installation of vector anodes XP4, and the completion of concrete repair works. Following these repairs, the waterproofing membrane was reinstated to the verge area.
The project team is now preparing for the next phase of work, which includes, the removal of the waterproofing membrane from the central reservation, completion of stages two and three of the concrete repair programme on the north deck and central reservation, reinstatement of the waterproofing membrane across remaining areas, installation of two Asphaltic Plug Joints (APJs) at both ends of the bridge deck, installation of a secondary gutter seal to the longitudinal joint, and removal of the temporary works shutters.
Following completion of the deck surveys, the extent of concrete repairs required was found to be significantly greater than the original scope. Repair locations on the south deck increased from 10 to 55, while the north deck increased from one repair to 25. As a result, additional hydro demolition visits will be required, alongside increased site attendance to deliver the expanded scope of works.
Despite this, the team continues to make strong progress on site with works expected to be complete in February 2027.
