Mini-Excavator for Earthbag Building

Mini excavators are very practical for leveling building sites, trenching and moving gravel, soil and other materials for earthbag building projects.

Anyone considering a large earthbag project should look into the advantages of mechanizing the building process with machinery since construction work by its nature is labor intensive. A foundation trench for instance could be dug by a mini-excavator or backhoe in a few hours versus a week of manual labor. The same trench could be filled very quickly with gravel using the same machine.

Touring earthbag building projects in Nepal has allowed us to gather hundreds of photos, dozens of hours of video footage, and discover lots of interesting new earthbag techniques and developments. I now have fresh content for lots of future blog posts. The volunteers and workers here are very good and so there’s quite a bit of innovation taking place. The photo above is one example of how earthbag builders in Nepal are improving the building process by sewing perfect corners on earthbags.

Most commercially available tornado shelters cost at least several thousand dollars. The materials cost for earthbag tornado shelters is around $300. That means almost pure profit for the builder.
