The photos on this site illustrate the method and the region. They do not show our work or crews, because we do not do the digging.

How the photos are used
All photos come from Wikimedia Commons under licences that allow commercial use. They were resized and recompressed; the circular crops are done in the page styling, not in the files. None of them shows work done by this site or by the operators it refers, and none is captioned as our crew.
The potholing photo shows a branded vacuum unit and the staff of a public agency in the background. It illustrates the method only. The share-alike licence on the suction excavator photo applies to that file, so any edited copy of it must be released under CC BY-SA 4.0.
