Estudio geotécnico in Argamasilla de Alba

The municipal district of Argamasilla de Alba is characterised by a predominantly calcareous bedrock consisting of limestones, dolomites and marbles, accompanied by significant proportions of gypsum, anhydrite and salts. These materials generally show good bearing capacity, which favours the execution of conventional shallow foundations, particularly in areas where compact gravels and sands are found. However, the frequent presence of gypsum, anhydrite and salts implies a risk associated with the possible dissolution and formation of voids, which calls for caution when assessing the definitive bearing capacity of the ground.

With regard to conditioning factors, the recorded seismicity is moderate, with 46 events over thirty years and a maximum magnitude of 3.6, which implies some attention during structural design but without requiring exceptional measures for earthquakes. Since karst is present, it is essential to verify the development of cavities before defining the foundation type. In addition, as the substrate is non-clayey, the risk of expansivity is ruled out, but the main challenge for the geotechnical study in Argamasilla de Alba lies in the investigation and treatment of possible karst-related phenomena and ground dissolution.
