Estudio geotécnico in Garachico

In Garachico, soils are predominantly composed of sandstones, conglomerates and flysch, materials that provide good mechanical competence for shallow foundations, although they may show variable compaction indices in certain layers. In smaller areas, granite, gneiss and other igneous rocks are found, which increase the ground’s bearing capacity and favour the stability of the foundation. Nevertheless, the generally low permeability makes it necessary to assess the possibility of deep aquifers and to control water-related construction effects on site.

The seismic activity recorded in Garachico is moderate, with 18 events over 30 years and a maximum magnitude of 3, which implies that seismicity is not a relevant structural conditioning factor in the area. No karst phenomena or risks associated with expansive clays are evident; therefore, the main aspect to consider lies in the proper characterisation of the heterogeneity of the strata and in ensuring a correct geotechnical study of permeability and the possible groundwater levels.
