Estudio geotécnico in Ateca

In the municipality of Ateca, compact gravels and sands predominate, followed by limestones, dolomites and marbles, as well as by slates and schists. These lithologies generally provide good bearing capacity, which favours the choice of shallow (direct) foundations, provided that the consistency of the materials is verified during the specific geotechnical study. The minor presence of gypsum, anhydrite and salts implies the need to consider the risk of dissolution, particularly in areas where evaporitic materials may be present close to the foundation level.

The seismicity affecting Ateca is very low, with a historically recorded maximum magnitude of 3.1, so the seismic influence on structural projects is minimal. Given the existence of calcareous formations, special attention should be paid to the possible presence of karstification; this phenomenon is significant and must be ruled out through geotechnical investigations before proceeding with the construction of the foundations. The non-argillaceous substratum virtually eliminates the risk of expansivity, so the main factor to consider in a geotechnical study for Ateca is the presence of karst processes or dissolution associated with soluble materials.
