Does our strata insurance cover diagnosing and repairing concrete cancer?

Concrete cancer, also known as concrete spalling, is a condition where steel reinforcement within concrete begins to corrode, usually due to water ingress. As the steel rusts, it expands and causes the surrounding concrete to crack, flake, or break away. Common signs include rust stains, bubbling or cracking concrete, and pieces of concrete falling off.

Strata insurance excludes damage caused by concrete cancer, as it is considered a gradual deterioration or a building defect, rather than a sudden or accidental event. These policies are generally designed to cover insured events such as water damage, storms, fire, or impact—not maintenance issues or long-term structural faults.

While it can be expensive to diagnose and repair, unfortunately, concrete cancer is usually considered a building upkeep issue and is a cost that the owners corporation must bear.
