Some wall plates in my basement are partially submberged in the concrete floor. This is pretty confusing to me, did somebody pour a new layer of concrete in the basement after some walls were up? Not all the wall plates are in concrete though.
One of the wall plates rotted away and there are holes in the concrete and the stone that goes under the floor is exposed. There is water coming through there. I am planning to fill that in with some concrete, does that seem alright?. (see pics)
Also at one point someone cut trenches in the floor to add a drain, presumably because there seems to be a lot of water under the floor. These run to a sump, but a drain guy told me that one of them actually stops short so that is another thing to fix. What is odd is that at the seems of these patched trenches, there is always a bit of moisture (see pics). It never gets really wet, just a bit of moisture perpetually. This makes me worried for finishing the basement, seems like it needs to be remedied before being covered up. Not sure what to do though. Any thoughts or advice on this messed up basement would be appreciated.
Partially submberged wall plate (and another that is actually the opposite, on a raised section of concrete):
Where a rotted wall plate was and some spots are open to stones underneath, planning to patch:
A seam between two rooms that is perpetually moist:*
