Follow-up on this post: I cleared a spot of land at the side of the house where the wood stack won’t block the view, and i put a few concrete slabs to isolate the wood from the ground.
I’ll let the slabs settle into the ground for a few days before starting to load it up some more with the first layers of wood. The ground is soft here, and my experience is that it will compress and shift for quite some time before settling down.
Looks solid. Why not gaps between the tiles to allow for ventilation ?
Edit: forget I said it. Probably nothing compared to the space beween the logs
