Floor Ideas in non clay areas

Hi, I’ve been building an Earthbag home in the UP for some years now. Structurally the house is complete, this summers project is the floor. The house is set four ft in the ground on top of a French drain.   There’s no clay to be found in the area, so cob and most earthen floors are out.
I was wondering if you can do cordwood right on tamped roadbase gravel? Or if it has to be on a concrete slab.
If there are other ideas out there I’m more then interested! Besides the no clay, rocks are incredibly scare so no flagstone or slate floor.

I remember hearing in one of Paul's podcasts, some guy just used a bunch of linseed oil on tamped earth. It apparently worked. I think cordwood would work on tamped gravel. I would try filling the gaps with dirt and covering the entire floor in some kind of oil.

That looks beautiful Kassey. I'm guessing that you used road base as your earthbag material?

Yes the bags are filled with road base gravel and plastered with lime! The roof is self supported built out of conventional lumber and tin.

I think I will try that. I’ve only ever read about linseed oil, are there others to try?

We used similar material for our root cellar/basement. Owen Geiger helped me relax about getting the perfect blend for filling earthbags.
