Added insulation for exterior basement walls,

[MathiasS]

What Totte has done can very well work even though it is not done as it should be. My house was built in 1925 and a few years ago I removed a chipboard floor that had been there for 25-30 years. The only thing that was moisture-damaged on that floor were the joists that lay directly against the concrete floor, and even those were not in particularly bad shape. The chipboards were completely unmarked by moisture damage.

Indeed, things that aren't supposed to work often do work anyway. When I renovated the basement here, some walls were framed directly on the slab. The bottom plate of the wall was even cast into the concrete for some reason. There's probably no one who can explain why that bottom plate wasn't completely rotted away despite quite a bit of moisture coming up through the slab.

Wigert - place the insulation on the outside even above ground level and hire some cheap labor skilled at plastering.
