For many Sydney apartment owners, magnesite flooring is a hidden issue that can significantly impact property value and structural integrity. This legacy flooring, once a popular choice, can lead to costly problems like concrete cancer. When it’s time to update your floors, navigating the strata approval process is your first and most critical step. What Is Magnesite Flooring and Why Is It a Problem? Magnesite is a cement-based compound used as a floor leveller in apartments built between the 1920s and 1980s. While it was once valued for its soundproofing and fire-resistant qualities, it has a major weakness: it absorbs moisture. This moisture absorption causes a reaction that releases chlorides, which in turn corrode the steel reinforcing beams within the concrete slab. The result? A serious issue known as “concrete cancer.” Signs you might have a problem include: Lumps or unevenness under your carpet. Cracks in your floor tiles. Rust stains or corrosion in the concrete. Neglecting this issue can lead to structural damage, health risks (due to potential asbestos content in older batches), and a major hit to your property’s value. It’s a ticking time bomb for your investment. Strata Approval: The First Step in Sydney In most strata schemes, the concrete slab and any flooring attached directly to it—including magnesite—are considered part of the building’s “common property.” This means you can’t simply start chipping it away. You need official written approval from your Owners Corporation or Strata Committee. Starting work without permission can lead to legal disputes and expensive orders to rectify the damage. Here’s a breakdown of the key steps: 1. Check Your Strata By-Laws Your building's by-laws are the rulebook. They dictate the process for renovations and, most importantly, financial responsibility. While strata is often responsible for the removal of common property like magnesite, some schemes have updated their by-laws to shift this cost to the lot owner, particularly if it's for cosmetic purposes. Always get a copy and understand what it says about flooring and common property. 2. Prepare a Detailed Proposal To get approval, you’ll need to provide the Strata Committee with a comprehensive plan. This should include: A clear description of the proposed work (magnesite removal, concrete grinding, and floor levelling). Proof of professional asbestos testing (if applicable). Quotes from qualified, insured professionals. Strata committees typically require multiple quotes. A timeline for the project, including start and finish dates, and working hours. 3. Submission and Approval Submit your proposal to the Strata Committee or Strata Manager. They will review it and, if the work involves a special resolution, it may need to be approved at a general meeting. A well-prepared and transparent proposal is crucial for a smooth approval process. Who Pays for Magnesite Removal? This is the big question. In an un-amended strata scheme, the Owners Corporation is generally responsible for the costs of removing the magnesite and repairing any concrete cancer, as this is maintenance of common property. However, if the by-laws have been updated, the lot owner may be responsible for the removal and levelling, while the strata remains responsible for any concrete cancer repairs. It’s essential to clarify this upfront to avoid financial surprises. A proactive approach is always best. Summary and Key Takeaways Magnesite flooring is a serious issue that needs professional attention. Don’t let the thought of strata approval deter you. A clear, well-documented approach will streamline the process and help you protect your investment for the long haul.
