A house made of sewn or filled bags is known as an earthbag house or sandbag dome. It uses stacked polypropylene or burlap sacks filled with soil, clay, or gravel, layered with barbed wire for friction, and finished with a protective plaster or stucco exterior to protect against UV rotting.
Earthbag building stacks damp soil-filled polypropylene or burlap bags, interlocked with barbed wire, tamped solid, and plaster-sealed. Using a portable handheld bag-closer machine (like the Eurosew NP-7A, EZGO 101, or NP-3II) drastically speeds up build times by applying a durable chain-stitch seal that keeps fill secure during heavy tamping.
Step-by-Step Build Process
- Rubble Foundation: Dig a 45–61 cm trench, pack with gravel, and lay two initial courses of gravel-filled bags to block moisture.
- Soil Mix & Fill: Blend subsoil (10–30% clay) with water until it holds shape when squeezed. Fill bags 75–80% full.
- Machine Stitching: Pull bag tops flat and run through a Eurosew bag-closer for a leak-proof seal in seconds.
- Placement & Wire: Butt bags end-to-end; lay two strands of 4-point barbed wire between courses to resist lateral shifting.
- Tamp & Stagger: Pound bags flat until solid, staggering joints like brickwork on every row.
- Finish & Plaster: Pour a concrete bond beam at the top for roof distribution, then plaster immediately to prevent UV damage.
