Can you build an earth bag cabin on bare rock?

Hi folks,

We are going to build a trial run earthbag cabin, 4m by 4.5m, that will be used as a home if all goes well.

We are considering build it on an almost flat section of bare rock, which is shaped so water drains away from proposed cabin.

Can one build with earthbag in this manner?  The stuff touching the bare rock will be either slate rocks as a stem wall or lime stabilised reject sand from the local quarry.

Any input, particularly with examples or photos much appreciated.

Extra info.......
Rock type, slate
Soil on site, rocky, almost no clay between topsoil and bedrock.
Location, ireland, climate like Oregon.
Wall material, reject sand from quarry

The only issue that I can see possibly arising from building on bed rock would be water seepage under the first layer of earth bags, that can be stopped with a lime mortar between the rock and the first layer of bags.

Thanks Bryant.
Do you mean an exterior ring of mortar stopping water seeping in from the outside or a layer of mortar under all of the first layer of bags?  i.e. the first layer of bags resting on mortar?

You will have no issues for strength, as Bryant spoke of, waterproofing the first layer is normal practise  and you have commented that water drains away from the proposed site.
Sounds great, and I would love to see an image when possible

Hello. I'm looking at doing this also on 12 acres I purchased in southern Colorado. The building will be a glass studio and I plan to adapt it to a 12 x 20ish rock slab on the property, although I may go further out on the front (south facing slope) which drops off the slab but would give me more area for a earthship style integrated greenhouse. Can anyone point me to a better explanation on waterproofing the first layer? Also looking for best price on bags, I'm ready to order. Thanks!
