Log house/Torpa foundation

[Roger1337]

There will be a new floor structure throughout the house, 220mm insulated, with underfloor heating in the entire house. A timber house with Torpagrund foundation.
I was thinking of shoveling out the foundation from wood chips and similar, possibly getting a vacuum truck so that all debris disappears.
My question is what is best for the house with the foundation, plastic in the foundation or not?
Please write suggestions
Best regards

There will be a new floor structure throughout the house, 220mm insulated and underfloor heating in the entire house. Timber house with Torpargrund. Planning to clear out the foundation from wood chips and similar debris, possibly bringing in a suction truck to remove all the waste. My question is what's best for the foundation of the house, plastic in the foundation or not? Please provide suggestions. Regards

Torpargrund or crawl space?
Wood floor structure?
Outdoor air ventilated?
Is the house on solid bedrock or loose sand?

The safest is probably an open plinth foundation on rock or dry coarse moraine with at least 500mm of air under the floor structure, completely without plastic and mineral wool, but it has its disadvantages too.

Cottage foundation vents are present, the house is situated high, I would say it's rock, not sand. It is a wooden beam structure, 220mm fully insulated with underfloor heating.
Why not plastic? It keeps ground moisture away?

The torpargrund is based on continuous burning so that the chimney heats the foundation. When you stop burning and supplying heat, it becomes a crawl space.

Ok, then it has been converted to a crawl space.
What do you think about plastic?

First and foremost, you need to find out the conditions. Are there any problems with the foundation? If so, what problems?

it is damp as most crawl spaces are, vents are present but maybe more are needed for more ventilation. the house is situated high.
