Optical confirmation
Specialized detection tools confirm the precise leak point after thermal scanning narrows the area.
Problem & causes
Guesswork repair costs you twice
Signs you have this problem
- A previous repair broke tiles or walls but did not fix the leak
- You want certainty before agreeing to any breaking work
- The leak source is not visible even after a thermal scan alone
- Hidden pipe leaks that are hard to locate by sound or sight
Common root causes
- Leaks travelling along slabs or pipes before surfacing elsewhere
- Underground or in-wall pipe leaks with no visible external sign
- Multiple possible sources that need to be ruled out one by one
- Previous repairs targeting the wrong spot due to incomplete diagnosis
How Gracia diagnoses
What we do differently
Combined with thermal imaging
We use both methods together for the most accurate diagnosis possible.
Minimal breaking
Precise location means only the necessary area is opened, not the whole wall or floor.
Hidden pipe leak tracing
Especially effective for in-wall or underground pipe leaks that are otherwise hard to find.
Our process
Symptom to warranty
01
Symptom
Bathroom leak, ceiling stain, wall damp or terrace seepage — what you see is the starting clue, not the diagnosis.
02
Inspection
On-site visual, thermal and optical checks. We do not quote a coating from a WhatsApp photo alone.
03
Evidence
Photos with marked points, thermal or moisture notes, and the limits of what the scan can prove.
04
Diagnosis
Cause labelled Confirmed, Probable, Possible or Excluded — then the minimum opening if we still need to verify.
05
Treatment
Quoted system, preparation, exclusions and testing. Work starts only after you approve the scope.
06
Warranty
The period on the quotation and certificate — not a generic banner number.
Real 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.
Inspection. Thermal scan of the ceiling below, optical check of floor-wall joints, fixture inspection.
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.
Warranty. Quoted 5-year bathroom wet-area warranty. Fixtures and later tile work excluded.

Optical confirmation is logged against the thermal map. Opening, if required, is the minimum point named in the report.
Warranty on this treatment
The warranty period and conditions on your quotation, completion record and certificate must match. If they differ, the quotation you signed is the source of truth.

Questions
Optical — frequently asked
Thermal imaging detects temperature differences from moisture, while optical detection uses specialized cameras to visually confirm the exact leak path — we typically use both together.
