The Hidden Dangers Lurking in Your Floors Many Sydney homes, particularly those built between the 1960s and 1980s, have a hidden threat beneath their carpets and floorboards: magnesite flooring. Once a popular choice for its soundproofing and levelling qualities, magnesite is now a known cause of "concrete cancer," a destructive process that can compromise your property's structural integrity. To make matters worse, this older material may also contain asbestos, posing a serious health risk to your family. At Elyment Group, we believe in empowering homeowners with the knowledge to protect their property and their loved ones. This guide will walk you through the essential safety protocols for magnesite removal and asbestos testing in Sydney. What Is Magnesite and Why Is It a Problem? Magnesite is a type of cement that was used as a floor topping. Its main flaw is that it's hygroscopic, meaning it absorbs moisture from the air. In Sydney's humid climate, this is a recipe for disaster. Moisture Absorption: When magnesite gets damp, it releases corrosive chloride ions. Concrete Cancer: These chlorides seep into the concrete slab below, causing the steel reinforcements to rust and expand. This process, known as concrete cancer, leads to cracking, spalling, and severe structural damage. Hidden Damage: The damage often goes unnoticed for years, hidden under floor coverings, until major and costly repairs are needed. The Asbestos Connection: A Double Threat During the era when magnesite was common, asbestos was frequently mixed into building materials to increase durability and fire resistance. If your magnesite flooring was installed before 1990, there's a significant chance it contains asbestos fibres. Health Risks of Asbestos When disturbed, asbestos-containing materials release microscopic fibres into the air. If inhaled, these fibres can lead to serious and fatal diseases, including: Asbestosis (scarring of the lungs) Lung cancer Mesothelioma It is crucial that you do not attempt to remove or disturb suspected asbestos-containing magnesite yourself. The Safe Solution: Professional Removal and Testing Protecting your home and family requires a professional approach. Here are the essential steps to follow, in line with NSW regulations. Step 1: Professional Asbestos Testing Before any removal work begins, a licensed professional must test the magnesite for asbestos. A sample will be taken and analysed in a NATA-accredited laboratory. This is the only way to be certain if asbestos is present. Step 2: Engaging a Licenced Removalist If the test confirms asbestos, or if you're dealing with more than 10sqm of any non-friable asbestos material, you are legally required to use a licensed asbestos removalist in NSW. For highly dangerous friable asbestos, a Class A licensed professional is mandatory. Step 3: Safe Magnesite Removal Professionals use specialised equipment and techniques to ensure safe removal: Dust Control: Industrial-grade dust extractors with HEPA filters capture up to 99.99% of harmful dust. Specialised Grinders: Diamond grinders are used to remove the magnesite layer efficiently and completely. Proper Disposal: All hazardous waste is sealed and disposed of according to SafeWork NSW regulations. Key Takeaways for Sydney Homeowners If your home was built between the 1960s and 1980s, be aware of the risks of magnesite flooring. Magnesite can cause "concrete cancer," leading to expensive structural repairs. Older magnesite flooring may contain asbestos, a serious health hazard. Never attempt a DIY removal. Always engage a licensed professional. The first step is always professional asbestos testing. Protecting your investment and ensuring a safe living environment is paramount.
