Bahareque
Bahareque is a traditional building technique used in regions such as Caldas, which is one of the 32 departments of Colombia. Bahareque, which came from the word bajareque, is an old Spanish term for walls made of bamboo ("guadua" in Spanish) and soil. Guadua is a common woody grass found in Colombia.  Based on Jorge Enrique Robledo’s book, Muñoz points out that this traditional technique of building evolved in Caldas from the first buildings constructed during the 1840s through the introduction of new materials, creating different typologies. Usually all these typologies use stone foundations. These typologies are: 1 . Bahareque de Tierra, 2. Bahareque de Tabla, 3. Bahareque Metálico, and 4. Bahareque Encementado. Each typology has a different structural design. For instance, the Bahareque de Tierra uses bamboo in both the frame and the structural panels and the plaster, and according to Sarmiento, is made from a mixture of earth and cattle dung. The Bahareque Encementado uses wood in the frame and bamboo ("guadua") in its structural panels, and the plaster is made by a kind of “reinforced cement” because of the use of steel mat between the bamboo panels and the cement plaster. In the 1840s, the first  settlers of Manizales, the capital city of Caldas, used Bahareque de Tierra in buildings that were usually single story. At the same time, in the rural areas, some farmers were using a mix of traditional building styles. This mix of traditional styles was Tapia, which is a pre-Hispanic construction technique, and bahareque. The first floor, "tapia", was based on compacted earth using wood earth forms, and the second floor was bahareque. In 1993, Jorge Enrique Robledo called this variation as “"Estilo Temblorero"”. The name derives from the fact that this new technique of bahareque had better performance in the  earthquakes (Spanish "sismo" meaning earthquake) since the first floor, which was rigid, absorbed the seismic energy, and the second floor, which was flexible, dissipated the energy. Consequently, the "Estilo Temblorero", which was used in a few farms and occasionally in the city of Manizales as temporary housing, gained favor after people saw that earthquakes were destroying buildings built with other construction techniques, such as Tapia. Those built with "Estilo Temblorero" remained standing. Because of the bahareque-materials flammability, and after the great fires of Manizales between 1925 to 1926, the trustworthiness of bahareque was lost. After these great fires and  the introduction of new construction techniques, such as reinforced concrete, new variations of the bahareque technique were introduced, leaving more trust in reinforced concrete than bahareque. These new techniques, which used concrete frames and bahareque facades and structural panels, were the most common structural designs in the reconstruction of the downtown that was swept by the great fires.
