Work in Progress
Earthbag building is a modern twist on perhaps humanity’s most important building tradition. Bags or tubes are filled with earth (a suitable aggregate, sometimes with additions, and if you’e really lucky it’ll just be the stuff you moved to make the site for your building), and then placed in walls; barbed wire is used as a tie or ‘mortar’, and the bags are ‘rammed’. Most often then, the earth cures, and makes solid walls which no longer rely on the bags or tubes for their integrity.
From its origins in the building of military bunkers, and in flood defence, earthbag has been developed and applied around the world. It has been widely tested both structurally and thermally.
The history of earth bag building is covered in detail in a very readable article by Kelly Hart.
