Downer - West End Road Bridge Repair

Originally built in the early 1900s the original concrete sections had shell aggregate from local beaches which had over time been severely compromised. Beam spalling and large cracks were apparent from the initial inspection from the ground.

Following onsite inspections with Sika, Downer and Auckland Transport, a full structural strengthening programme was signed off, and work commenced in March 2015.

Working off a scaffold set up under the main structure, while combatting high tide movements, we closely examined the bridge structure and used a number of repair systems to rectify spalling columns, cracks in beams and surface pitting, and using ferrous anodes to keep the steel inert. Utilising Sika concrete repair methodology this work was completed in May 2015.
