Estudio geotécnico in Carballedo

In Carballedo, sandstones, conglomerates and flysch predominate, forming most of the ground, while slates and schists appear as a secondary feature. These materials favour good bearing capacity and allow the adoption of conventional shallow foundations in most cases, always bearing in mind the possible local presence of water levels due to the existence of water bodies and local permeability.

The seismicity in Carballedo is classified as moderate, with 15 events over the last three decades and a maximum magnitude of 3.5, so the seismic risk is low and generally does not significantly condition structural design. As the substrate is non-clayey, any risk associated with expansiveness is ruled out; the main factors to consider in the municipality’s geotechnical studies are the lithological nature and local saturation.
