Rammed Earth – Tapia
Rammed earth, also known as taipa in Portuguese, tapial or tapia in Spanish, tàpia in Catalan, pisé (de terre) in French, bijenica in Serbian, and hāngtǔ (夯土) in Chinese, is a technique for constructing foundations, floors, and walls using natural raw materials such as earth, chalk, lime, or gravel. It is an ancient method that has been revived recently[when?] as a sustainable building method. Edifices formed of rammed earth are on every continent except Antarctica, in a range of environments including temperate, wet, semiarid desert, montane, and tropical regions. The availability of suitable soil and a building design appropriate for local climatic conditions are the factors that favour its use.
