Humidity rising up the capillaries is a valuable indicator of the state of conservation of earth structures. This situation is made worse by the condition of seismic zones, because the constructions present weaknesses where they need more resistance: in their bases. The result of this study has been the realization of a patented model of equipment and practice to evaluate the humidity of walls constructed in raw earth. This Test and device to evaluate the capillary absorption in soil specimens of adobe and rammed earth allows the characterization of the easiness of the water absorbed or lost in the soil used in construction. Thanks to these studies it is possible to analyze the reaction of the earth against capillary humidity and in relation to this, improve its quality, its texture, compaction density, composition, type and doses of additives. Our main purpose is the structural consolidation of heritage buildings. Keys words: device absorption test, absorption test, adobe, rammed earth, soil, moisture, capillary
