Curious what the symptoms of your under slab plumbing leak are?

I need to have a sewer line repaired and one of the options is to tunnel
under and the spot is about 5 feet from the exterior wall.

The company provided an estimate to dig using a "vaccon truck". Did a
search and cannot figure out what this is, is this a mini-horizontal
driller?

After the line is repaired, they said they will back fill with a
"non-exacavatable flowable fill". What type of material is this? Is it
plastic? If they run into a footing, do you know what is a standard
procedure? Break the footing there to get through, or go under the
footing?
Will the back fill material be able to fill the void ABOVE the footing
line?

Thanks,

MC
