After watching some videos on log cabin construction I’m not surprised they’re hard to take down.[/quote]
It’s very solid. My parents built a 11" yellow pine house 15 years ago. Someone framed it and they did all the other work.
Wood hardens as is drys out. If sealed from getting wet, will last for a very long time. To make wood rot, it’s done by fungi. (Which would make an interesting way for the game to ‘weaken’ walls with some of the creatures here).
Wood fungi need a source of infection, right temp, moisture, oxygen.
This is why for log houses and decks, you use a sealant. That stops moisture.
