Article about the history of earthbag building
A Short History of Earthbag Building by Kelly Hart The idea of making walls by stacking bags of sand or earth has been around for at least a century. Originally sand bags were used for flood control and military bunkers because they are easy to transport to where they need to be used, fast to assemble, inexpensive, and effective at their task of warding off both water and bullets. At first natural materials such as burlap were used to manufacture the bags; more recently woven polypropylene has become the preferred material because of its superior strength. The burlap will actually last a bit longer if subjected to sunlight, but it will eventually rot if left damp, whereas polypropylene is unaffected by moisture. Because of this history of military and flood control, the use of sandbags has generally been associated with the construction of temporary structures or barriers. 1978, a prototype house using an earthquake-proof stacked-bag type of construction was built in Guatemala.

Superadobe (sandbag and barbed wire) technology is a large, long adobe. It is a simple adobe, an instant and flexible line generator. It uses the materials of war for peaceful ends, integrating traditional earth architecture with contemporary global safety requirements. Earthbag Construction EarthBag Homes - you're standing on the building materials... earthbag home Long sandbags are filled on-site and arranged in layers or as compressed coils. Stabilizers such as cement, lime, or sodium carbonate may be added to an ideal mix of 70% sand, 30% clay. Straw may also be added. The earthbags are then plastered over with adobe.

Tiny Earthbag Homes Constructing an earthbag home is considered by many to be the most inexpensive method of building a home simply because the material is free and usually already onsite. The major cost associated with earthbag homes are the bags used to hold the earth which makes up the structure. The most common type of bags used are solid-weave polypropylene. These bags typically hold rice and grain during shipment and can be reused for building an earthbag home. You can of course buy the bags new as well.

Low-Cost Multipurpose Minibuilding One of the most practical structures on a small farmstead is a multi-purpose garden structure that can serve as a storage shed or cool pantry above ground, or as a root cellar or storm shelter below ground. You can build this multipurpose structure for about $300 using earthbag construction (bags filled with earth and stacked like bricks). And the skills you learn by building the dome will serve you well if you plan to build a larger earthbag structure or even an earth home. This earthbag shed is 8 feet in diameter inside (about 11 feet outside) and approximately 8 feet high. Plans could be scaled up to create 10- to 16-foot diameter domes. At the top of a larger dome, the earthbag thickness and cantilever (corbel distance) have to be adjusted slightly so it's more conical.

Earthbag & Papercrete Home: Hart House This is our first experimental earthbag dome. The interior diameter is 14 feet and the dome stands about 16 feet high. At first we tried filling the bags with the fine sand that it is built upon, but when we were partly done, the dome fell in because the sand couldn't hold the shape. Then we filled the bags with crushed volcanic rock (scoria) that provides better insulation and holds its shape much better.

Little Dome in Durban, South Africa This is the begining of our root cellar. Our neighbor came over with his back hoe tractor. He dug the whole thing in a couple of hours. The roots were amazing. I could have never dug the thing by hand. Low-Cost Multipurpose Earthbag Building - DIY Related Content Earth Building in Thailand I had heard there are thousands of new earthen houses in Thailand.

There is a makeshift hut made of nipa and, beside it, a room that doubles as the barangay's multipurpose hall. Despite the school's effort to make do with what is available, the students still find it difficult to learn because of the noise and overcrowding.

Also, my new Earthbag Building Guide and Earthbag Building DVD are now available. We built this earthbag dome at our home in Thailand for Mother Earth News Magazine in 2007.
