Rust stains and hollow sounds are warnings. Act before balcony edges fail.

Spalling starts when steel corrodes inside concrete. Early signs: rust staining, fine cracks parallel to rebar, hollow sound when tapped. Patch repair without steel treatment fails in one monsoon. Proper repair: expose, clean, treat, reinstate with structural mortar.
