Geotechnical study in Cordoba

In Córdoba, fine sands and silts predominate as substrates, along with frequent outcrops of limestones, dolomites and marbles. This lithological mosaic influences bearing capacity, with the presence of carbonate materials being particularly relevant: these generally provide good conditions for shallow foundations, whereas areas of fine sands and silts may exhibit more compressible behaviour and require compaction or strengthening studies. Hard, structured materials such as slates, schists and igneous rocks appear sporadically, providing favourable support where they outcrop.

Seismic activity in Córdoba is notable, with a record of 54 events over 30 years and a maximum magnitude of 4.6, which makes it necessary to incorporate seismic considerations into the structural design of new buildings. The karstification risk associated with limestones and dolomites requires a specific verification of cavities before deciding on the foundation solution, given the possibility of localised subsidence. The absence of expansive clays eliminates the risk associated with this behaviour. The main geotechnical constraint in Córdoba lies in the need to analyse the effects of karst and seismic action, especially in carbonate areas.
