Estudio geotécnico in Chirivel

In Chirivel, the predominant subsoil is represented by slates and schists, together with a significant presence of limestones, dolomites and marbles. These materials provide a mostly competent ground for foundations, especially in areas where metamorphic and carbonate rocks predominate, favouring good bearing capacity. Areas with compact gravels and sands also offer good conditions for direct support, whereas fine sands and silts require detailed characterisation. The presence of overconsolidated clays and marls, although occasional, can provide stability provided they are kept in dry conditions. Low-permeability formations may affect drainage and the possible rise of groundwater, especially in the upper horizons.

Seismicity in Chirivel is moderate, with 19 events over 30 years and a maximum recorded magnitude of 3.3, a value that does not represent a serious structural constraint, but does recommend seismic assessment in design. Since the subsoil is non-clayey, the risk of expansiveness in the foundations is ruled out. However, the considerable proportion of limestones, dolomites and marbles requires verifying the possible presence of karst phenomena, as there may be dissolution processes or underground voids that can negatively affect foundation stability. Therefore, controlling the risk of karstification is established as the main local geotechnical constraint.
