Why is carbon wood water resistant?

Is wood against soil doomed?
No matter what one does, in the long run, wood against soil is doomed to failure. Water always wins. If longevity is important to you, then use a system where the wood is not in contact with soil. I'm not a real "code" guy, but none of the structures I have seen where wood touches soil has lasted.

Charred Wood Is Incredibly Resistant to Rot
How Charring Preserves Wood

The process leaves a layer of char on the surface, which is essentially a layer of carbon protecting the wood. Since carbon does not rot, this layer shields the wood underneath from rot. The carbon layer ma…
