Concrete cancer is a serious structural issue affecting many coastal buildings across the Gold Coast and Northern NSW.

What Is Concrete Cancer?

Common Signs of Concrete Cancer:

• Rust stains

• Spalling or flaking

• Exposed reinforcement

Why Coastal Buildings Are at Higher Risk?

Salt air, humidity, and water exposure accelerate corrosion, making coastal buildings especially vulnerable.
