Estudio geotécnico in Priego de Córdoba

In Priego de Córdoba, the predominant substrate is made up of limestones, dolomites and marbles, which provides competent soils with a high bearing capacity, suitable for shallow foundations provided that homogeneity is confirmed and unfavourable elements are absent. The presence, although less frequent, of sandstones, conglomerates and flysch also contributes good geotechnical characteristics, whereas fine sands and silts are very unrepresentative and only found locally and at specific points. These formations, generally of low permeability, may give rise to shallow aquifers, although they do not adversely affect the general mechanical behaviour of the ground.

Seismicity in this municipality is classified as moderate, with 20 events in the last 30 years and a maximum magnitude of 3.4, which implies a low seismic risk for structural design. However, due to the karstified nature of the limestones and dolomites, it is essential to verify the presence of voids and cavities before carrying out any foundation work, as these processes can critically condition ground stability. In addition, the non-clayey substrate rules out expansivity-related risks, establishing the possible development of karst as the main geotechnical conditioning factor in the area.
