Cape Naturaliste

The Australian Maritime Safety Authority (AMSA) sought a turnkey solution from McElligotts to undertake repainting and repair works of the Cape Naturaliste Lighthouse in WA. A piece of history, this lighthouse was built in 1904 and still uses the original first-order Fresnel lens. To keep the structure in good shape and protect it from the elements, some remedial concrete repairs and protective coating were necessary.

Works we completed in this project included:

  • Stabilisation and repair of concrete cracks on the balcony and floor support corbels
  • Repointing of the stone work
  • Repairs of any severe corrosion damage to metallic substrates
  • Reglazing of the lantern room
  • Removal of asbestos materials
  • Replacement of plastic safety screens
  • Temporary navigation system setup, with reinstallation of the original system once all works were completed

Cape Naturaliste LighthouseAlthough this lighthouse was built primarily using limestone, some structural areas were constructed with concrete, which required attention in order to remain stable. After all toxic materials and miscellaneous repairs were taken care of, we applied a durable protective coating to the internal and external surfaces of the structure. We selected a coating system designed to withstand the corrosive-inducive environment surrounding it for many years to come.

Kununurra Dam Gate Remediation

From 2009 – 2014, McElligotts completed gradual remediation works on the Kununurra Dam Gates as part of a five-year contract for the WA Water Corporation. The Kununurra Dam consists of 20 gates, requiring us to complete works on at least four per year. The remediation process included abrasive blasting, scaffolding, and protective coating application on the internal and external structures.

Our team had to setup specialised equipment on barges and engineer specially-designed scaffolding for the unique conditions presented in this project. Each gate took about three months to finish, owing to the accessibility and sheer scale of each radial gate. We carefully assessed the surroundings and identified suitable primers and protective coatings that will last for many years to come.
