Quick Answer
To prepare the site for an earthbag construction project, clear the land of debris and vegetation, then level the ground to create a stable base. Next, lay down a grid of barbed wire to define the building's perimeter. Finally, compact the soil and lay down a layer of gravel to create a smooth surface.
Site Preparation and Grading
Clearing the land is the first step in preparing the site for an earthbag construction project. Remove any debris, rocks, and vegetation within a 10-foot radius of the building site. Use a skid steer or backhoe to level the ground, creating a stable base for the structure. The ground should be level within 1/4 inch over a 10-foot span.
Laying Down the Barbed Wire Grid
Next, lay down a grid of barbed wire to define the building’s perimeter. Space the barbed wire posts 10 feet apart, and attach a strand of barbed wire to each post. This will provide a sturdy framework for the earthbags and help to define the building’s shape. For a dome structure, use a geodesic dome pattern to create the framework.
Compacting the Soil and Laying Down Gravel
Once the barbed wire grid is in place, compact the soil beneath it using a hand tamper or plate compactor. This will create a stable surface for the earthbags. Next, lay down a 2-inch layer of compacted gravel to create a smooth surface for the earthbags to sit on. The gravel will also help to drain water and prevent erosion.
