Estudio geotécnico in Sanlúcar de Barrameda

In Sanlúcar de Barrameda, the subsoil is mainly formed by fine sands and silts, which suggests a generally medium bearing capacity and good drainability. However, the occasional presence of limestones, dolomites and marbles may introduce heterogeneity in the foundation profiles. Other materials such as compacted gravels locally improve strength, while the percentage of expansive clays is low. The widespread presence of aquifers and their high permeability make it essential to study the depth of the water table before deciding on the foundation type.

With regard to geotechnical risks, the area has moderate seismicity that must be taken into account in structural calculations, although the maximum recorded magnitude remains at low levels. The development of karst in the carbonate formations highlights the need to verify the possible presence of cavities or dissolution before carrying out any deep foundation. The main constraint for the geotechnical study in Sanlúcar de Barrameda lies in checking for karst and correctly characterising the aquifers hydrogeotechnically in order to avoid surprises during construction.
