Estudio geotécnico in Fuencaliente de la Palma

In Fuencaliente de la Palma, the subsoil is dominated by sandstone, conglomerate and flysch materials, representing more than 70% of the formations, together with a significant presence of granite, gneiss and igneous rocks. These ground conditions generally show a good bearing capacity, which favours the use of shallow foundations, although the local heterogeneity of the flysch may require a detailed analysis of the stratigraphy and compaction. The formations are permeable, highlighting the existence of perched aquifers or aquifers located at lithological contacts; therefore, it is essential to carry out a prior hydrogeological investigation to rule out problems caused by water rise and to ensure the stability of the foundation.

The seismicity recorded in the municipality is high, with more than 150 events in 30 years and a maximum magnitude value (Mmax) of 4.4, which makes it necessary to firmly consider seismic action in any structural project. There are no indications of karstification or expansive clays, so there is no particular risk associated with dissolution processes or volumetric expansion. Thus, the most determining factor for the geotechnical study in Fuencaliente de la Palma is the correct characterisation of the mechanical behaviour of the materials and the appropriate response to seismic loading.
