kindof expensive.

but if it saved the garage it would be a good deal.

on my other office building the sewer ran under a parking lot that was 8" thick concrete with steel rebar. and of course it was clay and of course it was partly collapsed and so every few years i had to have it jetted out. tearing out the concrete was cost prohibitive. i also would have had to set a manhole in the alley. so the jetting every so often seemed a bargain.
