Estudio geotécnico in Santisteban del Puerto

In Santisteban del Puerto, soils of phyllites and schists predominate, together with a significant presence of limestones, dolomites and marbles. This type of substrate provides a solid foundation with good bearing capacity for shallow foundations, although the occasional occurrence of gypsum, anhydrite and salts implies potential risks of dissolution, which must be considered when selecting and designing the foundation. The generally low permeability limits natural drainage, which may influence ground stability in specific areas.

The municipality shows moderate seismicity, with 19 recorded events over three decades and a maximum magnitude of 4, which advises considering seismic aspects in structural projects. Given the karstic nature of some ground conditions, it is essential to verify the existence of cavities before proceeding with the execution of the foundations, since karst can compromise long-term stability. The risk of expansivity is ruled out because the substrate is non-clayey, and the main technical constraint is the occasional presence of soluble materials and the potential development of karst-related phenomena in the subsoil.
