I have a peculiar house with all four types of foundations: timbers foundation in the east, crawl space in the west, basement in the north, and a concrete slab in the south. The latter is a classic 70s construction with wooden studs cast directly into the concrete. Measurements (Anticimex) have shown that moisture has entered the studs, but they have not yet begun to rot/smell.
The slab is under a single room with one exterior wall. Since we are renovating that room and replacing the parquet floor, it seems appropriate to address the issue once and for all. I've looked around a bit, but haven't really found a direct comparison of different options. Platon, Nivell, foam insulation, fans, plastic, EPS, vapor barrier :x
Which solution is best? I would prefer to avoid mechanical equipment (fans) and am reluctant to chip away and dig out for a modern slab construction.
Where can I turn for some expert help?

I had the exact same problem in my rec room, which I fixed with a Nivell floor. The hardest part was removing the joists, or rather, the joists that hadn't rotted away. In this floor, I also installed ventilation, so now it should be more resistant to deterioration! But if you don't have major moisture problems, you can build the Nivell floor with "natural draft" by leaving a small air gap between the wall and the floorboards. A colleague of mine did that, and it works well. I had it dripping wet with insulation directly on the concrete and other issues, so ventilation was the best option.
