⚡ Quick Answer
Roof leakage in India is usually caused by damaged waterproofing membrane, cracks in RCC slab, or gaps around parapet walls and expansion joints. The permanent fix requires exposing the slab, applying crystalline waterproofing, and re-doing the protective screed.
Diagnosis: Where is the Leak Coming From?
- Leakage throughout ceiling after rain → Terrace slab waterproofing failed → Full terrace treatment needed
- Leakage at one specific point → Crack in slab, or pipe penetration point → Targeted crystalline injection
- Leakage near walls/edges → Parapet wall connection failed → Seal parapet-slab junction
- Leakage only at expansion joint → Joint sealant dried/cracked → Replace with polyurethane sealant
- Leakage from bathroom of floor above → Missing waterproofing in bathroom above → Redo bathroom waterproofing
💡
Emergency Fix
For immediate temporary fix during monsoon: apply Dr. Fixit Raincoat spray or bituminous coating over the identified area from the terrace. Permanent fix MUST follow in the next dry season.
