New apartment buildings across Australia are suffering from widespread concrete defects, according to industry bodies, with some buildings requiring major repairs within their first decade. The problem has been attributed to poor workmanship, inadequate supervision, and cost-cutting during construction.
Scope of the problem
The Australian Construction Industry Forum (ACIF) and the Concrete Institute of Australia have reported that up to 10% of new apartment buildings may have significant concrete defects. These include cracks, spalling, and insufficient strength, which can compromise structural integrity and lead to expensive remediation.
According to ACIF executive director James Cameron, the issue is systemic. "We're seeing a pattern where corners are being cut, and the result is buildings that may not be safe for occupants," he said. The groups estimate that repair costs for affected buildings could run into the hundreds of millions of dollars over the next decade.
Regulatory and industry response
Several state governments are reviewing building regulations to address the problem. New South Wales has already introduced tougher licensing requirements for engineers and mandatory inspections during key stages of construction. Victoria is considering similar measures.
The Building Ministers' Forum, which includes federal and state ministers, is also examining whether national standards need to be updated. Industry bodies are calling for more rigorous testing of concrete and better training for workers.
Impact on homeowners and buyers
For residents, the defects mean potential safety risks and unexpected costs. Owners of apartments in affected buildings face special levies to pay for repairs, which can amount to tens of thousands of dollars per unit. Some buildings have had to install temporary supports or even evacuate residents.
"We bought our apartment thinking it was a safe investment, but now we're facing huge bills," said a resident of a Sydney building that required major concrete repairs. The problem also affects property values, with some apartments becoming unsellable until defects are fixed.
Long-term solutions
Industry experts say that addressing the issue requires a cultural shift in the construction industry. "We need to move away from the race to the bottom on price and focus on quality and safety," said Dr. Sarah Wilson, a structural engineer at the University of Melbourne. She advocates for mandatory third-party inspections and better enforcement of existing standards.
Some developers are already adopting more rigorous quality control measures, including using higher-grade concrete and conducting more frequent tests. However, industry bodies warn that without consistent regulation and enforcement, the problem will persist.
The federal government has announced a review of the Building Code of Australia, with a focus on ensuring that new buildings meet minimum durability and safety standards. The review is expected to report its findings later this year.
