A block of apartments has a water leak that they can not trace.
The building has a concrete slab floor and is built on sand, and adjacent is a tarseal carpark

Q. Will a thermal camera enable images below ground level?

Yes realise that Dan, but interested in what depth they can read to successfully. e.g. say 6"concrete slab - or 3" of tarseal - can it determine moisture below?

If there is a big enough temp difference from seepage or evaporation to affect the surface then yes (depends on unit how sensitive)

If its a slow leak 6" below surface and the water isn't surfacing there, or is same temp as the surrounding concrete it wont show a variance

If you've got water coming in it should highlight a cooler area somewhere

I'm pretty sure I still dont use mine to its capabilities
