Estudio geotécnico in Altorricón

In Altorricón, the predominant soils correspond to sandstones, conglomerates and flysch, covering almost 69% of the territory, accompanied by fine sands and silts as secondary materials. These lithologies usually show low permeability in the upper part, which favours the stability of shallow foundations, although the occasional presence of silts may affect bearing capacity, which is generally suitable for typical buildings if detailed characterisation of the near-surface layers is carried out.

Seismicity in the municipality is very low, with only about one recorded event in the last three decades and a maximum magnitude of barely 1.5, which minimises any seismic influence on structural solutions. There are no signs of karstification. With regard to expansivity, although expansive clays are subordinate and infrequent, it is advisable to identify their localised presence in the geotechnical study, especially in localised areas. The main conditioning factor for foundations in Altorricón is the precise identification of the finer or silty layers, highlighting the importance of an exhaustive geotechnical investigation to rule out near-surface heterogeneities.
