This house (pictures attached) is a 1960 concrete block wall home with what appears to be a poured concrete slab.
There is efflorescence on the lower 2 blocks pretty much around the exterior, and they have elevated moisture levels (45 - 100%)
What would cause this? I mean how was it supposed to not wick up water? In other words, did standard construction methods back then have a vapor barrier? Or could it have been like this since it was built?
There are no signs of water intrusion on the interior drywall (furred or 2x4 frame, couldn’t see the framing type)
I noted in the report that the blocks have efflorescence and are wet. Should I call for an engineer or something?
