Estudio geotécnico in Espirdo

In Espirdo, the subsoil is predominantly dominated by slates and schists, which account for more than 80% of the ground, whereas calcareous formations and compacted gravels occur only in minor proportions. These materials generally exhibit low permeability and provide a moderate to high bearing capacity, suitable for conventional shallow foundations. However, it is essential to carry out a geotechnical study that quantifies the heterogeneity and local variation of these materials in order to ensure the suitability of the foundation type to be used.

With regard to geotechnical risks, Espirdo shows high seismic activity, with 200 recorded events over 30 years and a maximum magnitude of 4.7, which means that the seismic action must be taken into account by advising during the structural design phase. There is no evidence of karstification or any risk of expansive soils, as the bedrock is not clayey. Therefore, the main constraint for any project in the area will be the correct characterisation of the geomechanical parameters and the integration of seismicity in the design calculations for the foundation structures.
