Fatbergs threaten sewers, but RMIT engineers have created a protective concrete coating to tackle the issue.

This results in severe sewer blockages, with data indicating that half of all blockages occur in the United States and 40% in Australia.

The annual cost of maintenance and rehabilitation for these blockages is estimated at US$25 billion in the United States and A$100 million in Australia.

To tackle this problem, the researchers have developed zinc-enhanced polyurethane coating.
