It starts as a small crack. Then, a few flakes of paint drop onto your floor. You brush it off as "old house problems." But then, a chunk of concrete—the size of a fist—crashes down.
In the engineering world, we call this Spalling Concrete. In Singapore's 2026 climate, where humidity is higher and heatwaves are more intense, this is no longer just an "old building" issue. It is a structural emergency waiting to happen.
- The "Cancer" Inside Your Slab Spalling occurs when the steel reinforcement bars (rebars) inside your concrete slab begin to rust. Rust occupies more space than steel, creating immense internal pressure. Eventually, the concrete simply snaps.
If you are seeing brown rust stains or "bulges" on your ceiling in Marine Parade, Clementi, or Bukit Merah, your home is telling you that the steel is expanding. Ignoring it doesn't just lead to leaks; it leads to structural instability.
