ceiling slab soffit water leaking
07 Jul 2026Water leakage at the ceiling slab soffit is a common defect in residential, commercial, and high-rise buildings. Water stains, damp patches, peeling paint, mould growth, or active dripping from the concrete slab soffit are often signs that water is penetrating through the reinforced concrete slab from the floor above, roof slab, balcony, bathroom, or external facade.
At KH Building Inspection, our experienced inspectors identify the root cause of the leakage instead of simply treating the visible symptoms. We conduct a comprehensive assessment using professional inspection methods to determine the source of water ingress and recommend the most appropriate repair solution.
