Rammed earth is a building technique where humid relatively sandy soil is rammed in layers between shutters made of metal or timber. It is often stabilized with cement or lime. It is a non-polluting energy-saving building material that lends itself for commercial production because it is a simple and rapid building technique. The poster stresses the need for proper soil identification and illustrates the various phases in rammed earth construction, and includes also typical details, specifications for the construction of the form and a typical wall section.
