Estudio geotécnico in Santa Cruz de la Palma

In Santa Cruz de la Palma, soils formed by sandstones, conglomerates and flysch predominate, representing the vast majority of the materials present in the area. These strata typically offer adequate bearing capacity for the foundations of buildings, allowing versatile options of the shallow type if there are no significant alterations or fractures. The occasional appearance of granite, gneiss and other igneous rocks improves the quality of the substrate, whereas hard clays and marls are infrequent and, due to their overconsolidated nature, do not usually pose relevant risks to the stability of typical foundations.

Seismicity in this municipality is moderate, with 21 events recorded over 30 years and a maximum magnitude of 4.7, which means that the seismic action must be considered in the structural design of any project. The area shows no risks associated with karst or with soil expansivity, given the non-clayey nature of the dominant substrate. Therefore, the main focus in the geotechnical analysis should be to ensure an appropriate characterisation of the mechanical properties of the flysch and sandstones, as well as a suitable consideration of the local seismic action.
