Rammed Earth Attributes


Rammed earth, an ancient building technique, may have originally been developed in climates where humidity and rainfall did not permit the production of soil block. For soil block to cure uncovered, there must be at least 10 rain-free days. Soil mixtures for rammed earth are similar to those for soil block. Soils with high clay content may be more suitable for ramming, as they tend to crack in blocks when curing.


Vernacular Architecture

Caribou_MAH_lgVernacular architecture is a term used to categorise methods of construction which use locally available resources and traditions to address local needs and circumstances. Vernacular architecture tends to evolve over time to reflect the environmental, cultural and historical context in which it exists. It has often been dismissed as crude and unrefined, but also has proponents who highlight its importance in current design.

It can be contrasted against polite architecture which is characterised by stylistic elements of design intentionally incorporated for aesthetic purposes which go beyond a building's functional requirements.[1]

Doug Beall, an architect living in Erie, Colorado, is armed with a vision to design and build indigenous Earthlodge homes that will strengthen family ties and reconnect our souls to nature not to mention they’re eco-friendly, too.


Building with Earthbags

SANY0011Using soil-filled sacks (earthbags) for construction has been recently revived as an important natural building technique for several reasons. It is inexpensive, using locally available site soil and polypropylene or burlap sacks, which often can be obtained free or at low cost. The technique demands few skills, and is easy to learn. In addition, building with the bags goes extremely quickly, much faster than any other earth-building technique. They are adaptable to numerous site conditions and can be used with just about any type of fill material available. When built properly, earthbags are extremely strong, and as the bags themselves are lightweight and easily transported, they are useful for remote locations or emergency shelter. Thus, it is a flexible means of construction usable in a wide range of situations to create a variety of forms and structures.
