 Basement Bottom Plate embedded in cement floor

I think I'd have done a bit of discreet surgery on the embedded bottom plate to see what's under it. Maybe drill a 1 1/2" hole somewhere.
The whole thing sounds fishy to me.

I agree. I'd be digging some stuff up to see what's what.
It's a termite attractant, it's probably rotten, there's the air sealing inadequacy, and it's just plain cheesey.
There's no good reason for it. Only bad reasons.

I sure couldn't think of a reason, let alone a good reason for the plates to be 1-1/2" embedded. Perhaps they for some reason added the 1-1/2 inches of concrete to a bad floor (whatever) and then added a second plate to the perimiter framing, raising it the 1-1/2"s seen now...I was curious if there was a common practice I hadn't seen... Guess not!
We gotta get in there to complete the post mitigation test and I'll try and explore further...Thanks!

Was it a load bearing wall?
On a project I worked on, the interior basement wall was built on a footing long before the basement floor was poured. We formed and poured a curb at the same time as the footing, so the bottom plate would have appeared to be 'regular framing'. But I can imagine someone not going through that process, or given the project, the finished elevation for the slab was changed and so the bottom plate got buried.

Guess I assumed that it wasn't load bearing. Interior basement walls. 10 yr old bsmt. I-Joist (I viewed) to what I assumed was an I-Beam to pillar to footing. Most of the area was finnished. An area of 30'x35' maybe.
I'll see what I can do for pictures next week. The followup Radon measurement was delayed due to the homeowner unplugging the measuring device for us...
Thanks...
Sorry, my guy didn't get pictures as requested...

Isnt it likely that the plates were once flush with the concrete floor and that an additional layer of concrete was poured to level or smooth the basement floor? If the sill plates are of Pressure treated lumber you can simply leave them alone and lay nailers between the studs to secure sheetrock if not already installed. basment partition walls go up quickly enough that I, personally, would remove them, fill the troughs and reinstall.

We have done this on a few projects where we underpinned the foundations, by pouring the concrete with a additive allowing it to be runny with out losing strength, adding extra "head pressure" to the concrete to get it under the old footings to ensure contact. was it possible that the house was post and pad, then had a foundation poured after? What year was the house?
