Sea Service Diving and Marine are currently appointed as the lead dive team to assist DM Roads, Sydney’s leading road network management provider, in the analysis of all concrete, steel and cast iron bridges that enter waters across NSW; a project overseen by NSW Roads and Maritime.

As a part of the inspection process, the Sea Service team perform an initial clean of all pylons and pile caps via either hand scraping methods or high pressure cleaning. Once the bridge has been professionally cleaned, our senior dive team conducts a detailed underwater video survey of all pylons and pile caps, carefully collecting additional measurement photos of any cracks or concrete spalling detected.

All cctv inspection footage is displayed on the dive support vessel at the time of survey and is recorded. The recorded survey is then provided to our client accompanied by a comprehensive bridge survey report, inclusive of the underwater photography. Repair works, if required, are then conducted on the bridge, which Sea Service Diving and Marine are available to assist with.

Just some of the major bridges surveyed recently include:

  • Spit Bridge
  • North and South Ryde Bridge
  • Windsor Bridge
  • all bridges within the Narrabeen Lakes
  • Manly Lagoon Bridge
  • Gladesville Bridge
  • Tartan Creek Bridge
  • Fullers Road Bridge and more.
