Estudio geotécnico in Villaquilambre

In Villaquilambre, the substrate is dominated by sandstones, conglomerates and flysch, making up more than 50% of the soils, with a significant presence of fine sands, silts and, to a lesser extent, gravels and compacted sands. This composition generally indicates good bearing capacities, although the heterogeneity of the flysch requires adequate characterisation to prevent differential settlements in the foundations. Extensive and highly permeable aquifers can influence the hydrogeotechnical regime, so it is essential to control the groundwater levels before defining the type of structural support.

Seismic activity in the municipality reaches a high level, with more than 200 registered events over 30 years and a maximum magnitude of 4.7, which necessitates incorporating seismic-resistant design criteria into the structures. Expansive clays appear in a subordinate manner and in climatic zones without a significant deficit, so the geomorphological risk due to expansivity is limited. In conclusion, the most limiting factors for a geotechnical study in Villaquilambre are mainly the high seismicity and the heterogeneity of the flysch, with specific investigation campaigns recommended to ensure the stability of the foundations.
