At the moment it suffers the risk of disappearance, product of the sociocultural processes lived in the territory during the last 50 years. This article describes the actions to rescue and value the system, through a technological research project with field and laboratory methodology in the region of Arica and Parinacota, in northern Chile. The results obtained through this research have allowed the mechanical and physical characterization of the system, the findings have been contrasted with the principles of safeguarding to assess its potential for recognition in the national system of safeguarding Intangible Heritage.
