As Sydney braces for another wet season, homeowners and property managers face a hidden threat lurking in older buildings: concrete cancer. This destructive issue, often sparked by water damage and magnesite flooring, can lead to costly repairs if not addressed early. In this article, we'll explore how Sydney's rainy weather fuels these problems and what you can do to protect your property. What Is Concrete Cancer? Concrete cancer, also known as concrete spalling, happens when steel reinforcements inside concrete rust and expand. This causes the concrete to crack and break apart, weakening the structure over time. Common causes include water ingress and chloride exposure. It affects buildings from the 1960s and 1970s, especially in coastal areas like Sydney. Early signs: Cracks, rust stains, and flaking concrete. The Role of Magnesite Flooring in Water Damage Magnesite is a topping material used in older Sydney apartments for soundproofing and levelling floors. However, it's highly porous and absorbs moisture easily, making it a prime culprit in concrete degradation. When water seeps in—often from leaks or heavy rain—it reacts with magnesite, releasing chlorides that corrode the steel rebar below. This sets off a chain reaction leading to concrete cancer. Why Sydney's Rainy Seasons Worsen the Issue Sydney's climate features frequent downpours, particularly from November to March. These rainy periods increase humidity and water exposure, accelerating damage in buildings with magnesite floors. Increased rainfall leads to more leaks through roofs, balconies, and windows. High humidity keeps magnesite damp, promoting chloride leaching. Coastal salt air compounds the problem, speeding up rust formation. Experts note that urban areas see spikes in concrete cancer reports after prolonged wet weather, turning minor issues into epidemics. Signs of Water Damage and Concrete Cancer Spotting problems early can save thousands in repairs. Look out for: Bubbling or peeling paint on walls and ceilings. Rust-coloured stains on concrete surfaces. Soft or crumbly flooring, especially in magnesite areas. Visible cracks wider than a hairline. Prevention and Repair Strategies Protecting your property starts with regular inspections. Waterproof balconies and roofs, and consider removing magnesite if it's compromised. For repairs, consult professionals for: Concrete patching and rebar treatment. Waterproofing membranes. Replacement flooring options. Learn more about remedial services at Elyment Group.
