Road base: A special clay/gravel mixture used to build roads. Most soils will work just fine.

Options for Finishing the Earthbag Dome

Plaster the entire dome. This is the fastest, easiest option to protect the dome if all you need is a tool shed or basic shelter. Mesh isn’t required, although it’s recommended on the areas previously mentioned.

Step-by-Step Building Schedule

Day 1: Use temporary stakes to mark building location. Remove and stockpile topsoil (to cover the dome later), then level the building site. Stockpile road base around the dome site in a continuous U-shaped pile about 4-feet high by 8-feet wide at the base.

What is earthbag building?

For those who don’t know, earthbag building uses polypropylene rice bags or feed bags filled with soil or insulation that are stacked like masonry and tamped flat. Barbed wire between courses keeps bags from slipping and adds tensile strength. The final plastered walls look just like adobe structures.

What is one community?

The following structure is purposed to clearly share our design parameters and goals in a duplicable and easily modifiable format. This structure is purposed to comprehensively address challenges before they arise while easily and transparently tracking the evolution of of all aspects of this component (through both top-down and bottom-up changes) until it is complete. In the following systems engineering approach:

Linear projects (walls, etc.)

Calculating how many bags you'll need for something like a wall is to simply figure how many square feet the face of the construction will be (H x L). A very basic rule of thumb is 4:1 - four bags for every square foot.
