Confirmed
Multiple evidence points support the cause.
What you are seeing
Symptoms and likely causes
Typical signs
- Hollow-sounding tiles in a shower or balcony
- Grout that will not dry
- Downstairs leak with a bathroom that “looks fine”
- You were quoted a full tile strip from a photo
Causes we actually check
- Water in the tile bed from open joints
- Failed membrane under the bed
- A pipe in the sunken filling
- Threshold or trap detailing missing
How Gracia diagnoses
Evidence before treatment
Tap test, thermal on the soffit below, moisture where the surface allows. The report names a minimum opening if we still need to verify. “Break all tiles” is not a diagnosis.
Large-format tiles in Madhapur and Gachibowli showers make guesswork demolition expensive. We would rather spend the first visit on the scan.
Probable
Evidence indicates the cause; further verification may still be required.
Possible
One or more clues exist, but the evidence is not enough for a firm conclusion.
Excluded
Inspected, and no supporting evidence found in the inspected area.

Local case
Bathroom leakage into the floor below — LB Nagar
Problem. Water marks on the living-room ceiling under a first-floor bathroom after every shower.
Evidence. Moisture concentrated at the bathroom floor-wall junction, not at the tap line.
Probable. Failed wet-area membrane at the floor-wall joint. Concealed pipe leak not supported by the scan; excluded pending any opening.
Treatment. Injection grouting at the joint, two-coat wet-area system. Plumbing left in place — not in scope.
Testing. Shower test after curing; ceiling below checked the next day.

About this problem
Thermal on the ceiling below, tap test, grout and threshold inspection, moisture meter on adjacent plaster. That narrows the zone. Opening is the last step, at the point the evidence names.
