Earthen Bag

Earth Bug Structures

Earthbag, also known as superadobe or soilbag, is a structural construction material used in natural building that requires easily found resources. It is mainly made of polymer bags (burlap sack) filled with soil, that is, a mixture of clay, silt, and sand.

Product description Brand name and product description

Earthbag construction is a construction material that is both strong and can promote quickly building. 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 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.
