Geotechnical study in Sober

In Sober, substrates of slates and schists predominate, together with a significant proportion of granite, gneiss and other igneous rocks. These materials are typically competent and provide a high bearing capacity, which is favourable for most shallow and deep foundations. Compact formations of gravels and sands, although less common, also provide good conditions for supporting foundations, provided that their compactness and continuity are verified. The occasional presence of sandstones and conglomerates reinforces the geotechnical stability of the area, and water bodies may locally indicate the saturation of the nearest soils, which should be taken into account during the excavation phase.

Seismic activity in the municipality of Sober is considered very low, with only 5 events in the last 30 years and a maximum recorded magnitude of 3.1, so seismicity does not represent a significant concern for structural design. The non-clayey bedrock eliminates the risk of expansivity, which simplifies the selection of foundation solutions. In conclusion, the main geotechnical factor to evaluate in Sober is the location and accurate characterisation of the competent horizons to found on, especially in areas close to watercourses or where the rock is weathered.
