Sod as a building material - Wikipedia (en.wikipedia.org)

Sod is the upper layer of soil held together by (usually grass) roots. It was used as a building material, in a similar way to soilbags.

Or not well-designed. I'm sure someone like Mark Oehler could've figured something out. I don't have much sod here in central Finland, unfortunately, to try something, neither did he I suppose. I still think of how to cover the roof in living grass though, this is perfect roofing material IMHO once we figure out how to fix leakage without resorting to plastic sheets that my grass seems to tear like they are not even there.

Stainless steel perhaps

Yes and no. There are grades, variations of acidity and oxidative state of medium through the year. It's heavy. It warps differently from everything else with temperature variation. Most of all, it is expensive.

I was also considering glass or clay overlapping tiles. Would be cool to cast huge ceramic panel, but it will crack, unless soil matrix holds it together. Shingles under sod might get roots growing through.

Another possible approach would be to allow leaks deliberately, then leave porous medium below the locking level with airflow access - so that any leaked water would be carried away with warmer air rising from habitation levels or even rhtough ventilation system or stove exhaust.

So much to study.
