root-cellar plan

here is the general plan for the root cellar.



the U-shape on the top of the bags is a row of cement beam block that will hold the entire roof to the bags via re-bar pounded down into the earth bags. i opted for this instead of using bags to create my arch because i plan to pile a bunch of dirt on top of the root cellar and i believe this will be stronger. we'll grow some ground cover over the top of the root cellar and pump house. earth roof for the pump house plan will be shown at a much later date.

Hey Karl! Looks good; may I ask what is your spacing and size on your rebar in the walls and in the arch? Also, you must be going to apply the concrete fairly stiff over the metal lathe since it does not appear that you are using formwork to pour onto?

ed rex,

each beam-block will have a hole drilled through it with a piece of 1/2" rebar pounded through it. there will be 1/2" rebar wired perpendicular at two separate vertices. i also plan to cement-in several arch bent 1/4" rebar following the shape of the vault wired to the metal lath. i also have a bucket of 12" by 3/32" carriage bolts that i'll drive into the earth bags at most every block joint.

Great to see others building with earthbags. We try to cover everything going on in the earthbag building movement and may tell our readers about your project in an upcoming blog post.

How large is the span? (What is the distance between the earthbag walls?)

How much soil will you put on top? (How many inches thick?)

Thanks,
Owen

[I'm not sure this worked the first time, so am resending it again.]

owen, wall to wall distance is eight feet. there will likely be 2 feet of soil covering the cellar. my cellar is a hybrid and was done in a vacuum. i have had no classes and read about the concept years ago.

I would love to build one of these for our home, but we live in an area that has hot summers 100+ degrees. Would it still be cool enough inside to store our canned foods?

karl said...

tahtimbo, probably cool enough but likely too humid to store canning.
