The “taipa” technique in Brazil northeast
The technique of rammed earth has been used in humanity from ancient societies as ancient Egypt, back in 5.000 bC. It is usually related to regions where water resources is a problem. It consists in a variation of the adobe technique.
In the brazilian “sertao”, region whose characteristics are very like a desert, the rammed earth has been used as the most common building technique for houses for humble people.
According to the architecture brazilian historians Schmidt (1946), Barreto (1949), Vasconcellos (1961), Corona & Lemos (1972) e Pisani (2004), the houses are usually built using local wood as foundation, that usually don’t reach very low depths. For the structure, a grid of wood is created, and later the wall is filled with mud and dried plants.
