How is a swimming pool leak detected by thermography? To identify possible water leakage areas in the swimming pool structure using non-destructive thermal imaging.
Thermal image of the swimming pool channel leak.
You can see this thermal image now — here’s a casual but clear explanation:
In this thermal scan, you’re looking at temperature differences across a swimming pool surface (probably the wall or floor). Here’s the breakdown:
- Color meanings:
- Red/Pink areas are warmer (32–34.7°C).
- Blue/Green areas are cooler (around 31.1°C).
- Yellow zones are in-between temperatures.
- The wavy blue-green crack shape in the middle is the important part — it suggests a possible water leak.
- Leaking water usually cools down the surface because water evaporation absorbs heat.
- So, when you spot a cooler, irregular, vein-like pattern like that, it’s a strong sign of leakage.
- The yellow bands might be structural joints or repairs — they are holding more heat than the leak areas.
In short:
The cold wavy pattern you see is water escaping and cooling that part of the structure. That’s where your leak is happening.
Thermal cameras are super handy for this because the temperature contrast makes leaks “glow” differently from the rest of the pool.
To sum it up in simple terms
To sum it up in simple terms:
- This thermal image shows a swimming pool surface being tested for leaks.
- The wavy blue-green path running vertically in the middle is cooler (around 31.1°C) compared to the surrounding areas (which are warmer, 32–34.7°C).
- Cooler areas like this often indicate leaking water — because as water leaks and evaporates, it cools the surface.
- The straight yellow line could be a construction joint or a floor/wall joint — water might be leaking along it or from cracks connected to it.
- The surrounding red/pink area is hotter and dry, meaning no leaks were detected there.
- The date/time stamp at the bottom shows it was captured on 2025/04/27 at 12:21 PM.
👉 Final simple explanation:
This image shows a water leak trace in a swimming pool, visible as a cooler (blue-green) wavy pattern in a hotter background.
Swimming pool structure water leak.
now looking at this third thermal image you uploaded. Here’s the casual breakdown:
- Colors again:
- Red/Pink areas = Hotter (up to 35.0°C).
- Blue area = Much cooler (around 32.0°C).
- Yellow/Green = Transition zone between hot and cold.
- In the center, you have a clear blue triangle-like patch, surrounded by a yellow/green “halo”.
- Next to it, you can see a thin yellow vertical line — that’s likely a joint line or a crack.
👉 What this means:
- The cooler blue patch strongly hints at water accumulation below the surface — likely due to a leak nearby.
- Water spreads sideways underground, creating these “cold islands” under the surface.
- The vertical line could be the source or path of the leak — water might be seeping out from it and spreading into the slab or tiles.
Quick Casual Summary:
- You have leak signs here too — cooler water has collected under the surface.
- The leak is probably along that vertical joint/crack near the blue patch.
Overall from your 3 images:
| Image | Observation | Conclusion |
|---|---|---|
| First Image | Wavy cold line | Active leak trace |
| Second Image | Uniform cold area | Moisture accumulation (slow seepage?) |
| Third Image | Cold patch + near crack | Localized leak + possible spread |
