Construction works on two breakwaters for the exciting Ocean Reef Marina project are underway, reports the Government of Western Australia.
The two-kilometre-long breakwaters, each rising up to 18.5 metres from the ocean floor, will protect boats and users within the marina.
The breakwaters will have a limestone core, surrounded by granite, for protection from the elements.
Approximately 650,000 tonnes of limestone rocks – ranging from 0.5 to three tonnes each – and 300,000 tonnes of one to 10-tonne granite rocks will be delivered to the site from early March.
Some granite and limestone from the existing breakwater will also be reused.
