Earthbag Building

Dirt is the most fundamental element of earthbag construction, and it is the most abundant element on earth. Earthbag structures have been employed for many years and a variety of uses.  These include flood control and temporary shelter during times of war. The principles that made this a sound choice in the past make earthbag building for residential or commercial use an innovative sustainable building strategy for the future. Earthbag structures are still used by many people throughout the country simply because it works. Nothing compares with the beauty of an earthen home such as earthbag building. For protection from the sun’s rays, earthbag buildings are typically covered with a plaster.

Credit for developing contemporary earthbag construction goes to Architect Nadel Khalil and Illiona Ourram of the California Earth Art and Architectural Institute known as Cal-Earth. Their students have taken the earthbag buildings throughout the United States.

Simplicity of Earthbag Constructions:

Earthbag construction is also known as Flexible-Form Rammed Earth (FFRE). Earthbag Building utilizes the ancient technique of rammed earth in conjunction with bags and tubs as a flexible form. Earthbag construction does not require as much time, attention, or forms as adobe or rammed earth construction requires.


Environmental Benefits of Earthbag Construction:

Earthbag homes begin with the bags themselves, which can be recycled grain bags, misprints, burlap, polypropylene, or other economic choices—they are both sustainable and cost-effective. The fill can be on-site soil or other local materials. Depending on the needs and uses of the completed project, certain materials are selected for either insulation or providing thermal mass. Generally, the fill is of a mineral composition and not subject to decay.

Because these structures can take an endless variety of shapes, the need for traditional building materials, such as wood or steel, is negated. This saves both energy and precious natural resources.


Other Earthbag Building Advantages:

Aside from being a comprehensive eco-friendly building solution, there are a number of other benefits afforded by this building practice:
