Advice on proper foundation?

Hello,

We are building a multi-dome earthbag home on a slope. We just had the area excavated and leveled. Our footprint is somewhat rectangle with the long sides going west to east, same direction as the slope. So, the west side was excavated and the east side was filled with dirt to level out.
My crude drawing hopefully will give you a visual. (Not to scale) We will have multiple domes so it will not be just one foundation but several along the entire building area.
Any suggestions on how to do these foundations, especially where we added dirt? * we plan on backfilling to an extent when done. I'm thinking use gravel bags on top of ground on west side, and gravel trench then gravel bags on east side until above ground level.

Thanks
Jim

First I would recommend a read through of this post...Raised Earth Foundations...on good natural and traditional modalities applicable to many of the dry laid stone, rammed earth, bagged, gabion, cobb, etc wall systems, as well as others.

This will provide insights and links to more to read.

In general a gravel trench is going to serve you well as a generic description of intended recommendation (each site is different and more detail is needed/required to "spec out" any job.)

In general, also, building off "fill" is not recommended unless the fill is graded, has know angle of repose and is "tectonically stabilized."

Good luck, and we will all help where we can.

Regards,

j
