Construcción con sacos de tierra
La construcción con sacos de tierra (a veces llamados sacos de arena) es algo viejo y nuevo. Los sacos de arena se han utilizado durante mucho tiempo, especialmente por los militares, para crear barreras protectoras fuertes o para el control de inundaciones. Las mismas razones que las hacen útiles para estas aplicaciones se trasladan a la creación de viviendas. Dado que las paredes son tan sólidas, resisten todo tipo de clima severo (o incluso balas) y también resisten calamidades naturales como terremotos e inundaciones. Se pueden montar de forma sencilla y rápida con componentes de fácil disponibilidad, por muy poco dinero.
La construcción con sacos de tierra ocupa un nicho único en la búsqueda de una arquitectura sostenible. Los sacos se pueden llenar con materiales naturales locales, lo que reduce la energía incorporada comúnmente asociada con la fabricación y el transporte de materiales de construcción. El material de relleno es generalmente de composición mineral y no está sujeto a descomposición (incluso cuando está húmedo), es atractivo para las alimañas o quemable... en otras palabras, es extremadamente duradero. El material de relleno generalmente no es tóxico y no liberará gases nocivos al edificio.

Recurso claveIntroduction Given the proper facilities necessary to store seeds long-term, whereby low temperature and low humidity are kept stable over time, it is very possible to store most orthodox seeds for several years at a time in the tropics (Harrington, 1972). Unfortunately, implementation and...

In addition to lateral support, buttresses (as well as curves) follow criteria for determining their height to width ratio. For every foot (30 cm) of wall height, add six inches (15 cm) of width to the wall, either as total thickness, or as a curve or buttress. In other words, theheight to width...

Building with earthbags (sometimes called sandbags) is both old and new. Sandbags have long been used, particularly by the military, for creating strong, protective barriers, or for flood control. The same reasons that make them useful for these applications carry over to creating housing. Since...

Roundhouses are perhaps the simplest, fastest, easiest earthbag structure to build. We’re extremely pleased with the results, especially in terms of strength and cost. This is one of the strongest structures I’ve ever worked on in my 30-plus year construction career. The main impression is one of...

For those who don’t know, earthbag building uses polypropylene rice bags or feed bags filled with soil or insulation that are stacked like masonry and tamped flat. Barbed wire between courses keeps bags from slipping and adds tensile strength. The final plastered walls look just like adobe...
- 20/1/2004 Building with earthbags is gutsy. Gutsy because only the brave take up a construction method so different from the conventional. Gutsy because people build homes with this technique when they’ve just learned it. Gutsy because the materials are basic, elemental, primal. And gutsy, indeed, because...
