Earthbag Dome

Earthbag construction uses stacked courses of polypropylene bags filled with a mix of earth, sand and binder. Two lines of barbed wire are laid out between each course to maximize interlocking between bags.

Dome exterior finishes are made of cob (earth + sand + straw) and eco-bricks (plastic bottles filled with trash). They are covered by shingles made out of plastic bottles and nailed to the earth bags.
