Estudio geotécnico in Xove

In the municipality of Xove, local geology is mainly dominated by the presence of sandstones, conglomerates and flysch, which constitute almost 50% of the soils, followed by slates and schists in a proportion that is also significant. These materials, characterised by low permeability, provide competent behaviour from the standpoint of bearing capacity, making them suitable for shallow surface footings in most cases. The occasional presence of granite, gneiss and other igneous rocks increases the geotechnical stability of certain areas, although it may require adaptation of excavation techniques due to their hardness.

As regards seismicity, Xove shows very low seismic activity, with only 9 events over the last 30 years and a maximum magnitude of 2, which does not represent a relevant constraint for structural design. The analysis of expansivity reveals a non-clayey substrate, ruling out potential risks associated with expansive soils. In conclusion, the key factor to consider in the geotechnical studies for Xove is the appropriate characterisation of the continuity and physico-mechanical properties of the sedimentary materials; and low permeability is an aspect to take into account in the management of groundwater and drainage during the foundation phase.
