Abstract. Constructive techniques based on low environmental impact materials are increasingly gaining importance in developed and developing countries as a way to mitigate the effects of intensive use of industrialized materials such as steel, cement, concrete, among others, responsible for high energy consumption and emission of greenhouse gases. The aim of this work is to promote a re-reading of a vernacular constructive technique widely used in the colonial period, the wattle and daub, aiming at its application in social interest habitatio. Innovations were incorporated in relation to the materials and the traditional production process, in order to allow the pre-fabrication of modular units that fit the pillars of the building. A prototype of the modular unit was produced and mechanically tested using a self-compacting soil–cement-sisal fiber mortar and a bamboo framework (Bambusa Tuldoides) as reinforcing material. Bamboo is a native plant in Brazil with accelerated growth, without any need of replanting, low cost, good mechanical properties and high capacity of carbon sequestration in its biomass. The bamboo framework was assembled with sticks rods of dimensions 1.55 x 0.03 x 0.005 m (length, width, thickness, respectively), obtained from the subdivision of the culm into four parts. A three-point bending test was performed to characterize the mechanical behavior of the modular unit (prototype), designed with dimensions of 1.5 x 0.12 x 0.30 m (length, thickness, height, respectively). The purpose of this research is to revive and valorize a constructive technique that is widespread in some Latin American countries, with great economic, technological and environmental advantages.
