Living in Sydney's stunning coastal suburbs offers breathtaking views and a relaxed lifestyle, but it comes with hidden challenges. One such issue is magnesite damage, a problem that plagues many older homes near the sea. If you're a homeowner in areas like Bondi, Manly, or the Northern Beaches, you might be wondering: is your property at risk? In this article, we'll explore what magnesite is, why coastal locations amplify the danger, and how to protect your investment. Source: Inspired by insights from Elyment's guide on concrete cancer in Sydney. What Is Magnesite Flooring? Magnesite flooring was a popular choice in Australian homes built between the 1920s and 1980s. It's a cement-like material made from magnesium oxychloride, often used as a topping over concrete slabs for soundproofing and levelling. Common in apartments and older houses. Contains high levels of chlorides, which can react with moisture. May include asbestos in some older installations, adding health risks. While it seemed ideal at the time, magnesite breaks down over years, especially in humid environments. Why Sydney's Coastal Homes Are More Vulnerable Sydney's coastal climate – with its salty air, high humidity, and frequent rain – accelerates magnesite deterioration. The chlorides in magnesite attract moisture, leading to corrosion of steel reinforcements in concrete floors. Salt from sea breezes speeds up the process, causing "concrete cancer." Areas like the Northern Beaches or Eastern Suburbs face higher risks due to proximity to the ocean. Rainy seasons in Sydney exacerbate water ingress, as noted in recent studies on coastal erosion. Properties near the beach are particularly susceptible, with experts warning that delaying action can lead to costly repairs. Signs of Magnesite Damage to Watch For Early detection is key. Look out for these common indicators in your home: Cracked or bulging tiles and floors. Hollow sounds when tapping on the surface. Rust stains or spalling concrete. Uneven surfaces or "sweating" floors in humid weather. If you spot these, it's time to consult professionals. Ignoring them could result in structural failure. The Risks and Consequences of Ignoring Magnesite Damage Beyond cosmetic issues, magnesite damage poses serious threats: Structural Integrity: Corroded steel can weaken slabs, risking collapse. Health Hazards: Potential asbestos exposure and dust from crumbling material. Financial Impact: Repair costs can soar into the tens of thousands, plus decreased property value. In coastal Sydney, where homes are already vulnerable to erosion, this adds another layer of concern for homeowners. What Can Homeowners Do to Mitigate the Risk?
