Estudio geotécnico in La Puebla de Cazalla

In La Puebla de Cazalla, strata of sandstone, conglomerates and flysch predominate, forming the geological base for most foundation works. These materials, typical of the area, usually exhibit good bearing capacity, although the presence of flysch may involve a certain heterogeneity in the ground’s physical-mechanical characteristics. The general impermeability of these soils reduces risks associated with the migration of water, providing favourable stability for conventional foundations, provided that detailed characterisation is carried out for the proper selection of the type of support.

As regards the conditioning factors, seismic activity is very low, with only 3 events over 30 years and a maximum magnitude of 3, so that seismicity has little impact on structural design. However, the possible presence of karst phenomena makes it essential to thoroughly verify the existence of cavities or dissolution before founding, as these processes can significantly affect the long-term stability of the ground. The absence of clayey soils rules out the risk of expansiveness, consolidating karst as the main geotechnical conditioning factor in the initial stages of the study.
