| Résumé: | When some volumes of walls, roofs or plaster of earthen architecture are lacking, conventional “grafts” made with plastic material have been used as fillers. Although this strategy solves part of the problem, the reality is that adequate adhesion with the substrates is never achieved due to the shrinkage of the integrated areas. Given this problem, a procedure has been developed in which, from the control of humidity, the addition of lime and compaction processes will generate much more stable components. Thus, a better link to the historical substrate, greater density, water saving is achieved and the retraction and detachment of the integrated parts is eliminated. In addition, over time the lime reacts with the clays and acquires greater strength and durability. This article describes some theoretical and practical considerations for the implementation of this conservation and restoration technique, which has a high application potential due to its practical, economic and ecological benefits. |
