Estudio geotécnico in Alcalá de Guadaíra

In Alcalá de Guadaíra, fine sands and silts predominate, accounting for almost half of the soils, followed by formations of limestones, dolomites and marbles. This mixed substrate provides good conditions for bearing capacity, especially in the presence of gravels and compact sands, which favour shallow or semi-deep foundations, depending on the case. The presence of extensive, high-permeability aquifers requires an appropriate assessment of the groundwater level, as it could influence the type of foundation recommended and the control of possible differential settlements.

Seismic activity in Alcalá de Guadaíra is very low, with minimal seismicity and Máx (Mmax) values below the thresholds of structural significance. The absence of expansive clays in the substrate rules out significant risks associated with volumetric movements due to hydration. Likewise, the lack of localised karst processes means that underground voids that could compromise foundation stability are not expected; the control of the groundwater level and the lithological composition are therefore the main factors to be considered in local geotechnical studies.
