Estudio geotécnico in El Puerto de Santa María

In El Puerto de Santa María, soils formed by limestones, dolomites and marbles predominate, providing a firm substrate with high strength. This lithology confers a marked bearing capacity, enabling the use of shallow (direct) foundations in most construction situations. The high permeability of the ground indicates the presence of extensive and productive aquifers, which may require particular attention in the design of drainage systems and protection against possible rises in the water table.

The seismicity of the municipality is very low, with only 3 events over 30 years and a maximum magnitude of 2.9, so seismic risk does not represent a relevant constraint in structural design. Although expansive clays exist in a subordinate manner, their frequent occurrence in climatic zones without moisture deficit nullifies the risk of expansivity in most projects. Therefore, the main constraint to take into account is hydrogeotechnical management due to the potential saturation of the aquifers in permeable horizons.
