Earthen Bag

(construction material)

Earthbag construction is a method to create structures which are both strong and can be quickly built. It is a natural building technique that evolved from historic military bunker construction techniques and temporary flood-control dike building methods. The technique requires very basic construction materials: sturdy sacks, filled with inorganic material usually available on site. Standard earthbag fill material has internal stability. Either moist subsoil that contains enough clay to become cohesive when tamped, or an angular gravel or crushed volcanic rock is used. (Sandbag structures with sand fills are an alternative technology and require very different construction details). Walls are gradually built up by laying the bags in courses — forming a staggered pattern similar to bricklaying.

Target region(s)

Earthen bags can be used anywhere that the user has access to enough earth or dirt to compact into bags to form walls.

Distributors/implementing organizations

Varies. While some organizations have marketed and commercialized earthen bags, they can also be made onsite out of readily available materials.

Market suggested retail price

Certain sources claim earthbag homes can be built for as low as $16 USD per square feet.

Competitive landscape

Any standard earthen block or average brick has a similar function as an earthen bag.

SDG targeted

Goal 1 and 11: Aims to provide fast, affordable, and durable shelter.

Target user(s)

Any person, community, or organization that wants to construct a structure out of readily-made material: earth.
