Estudio geotécnico in Corcubión

In Corcubión, sandstone, conglomerate and flysch soils predominate, accounting for almost the entirety of the local geotechnical subsoil. These formations exhibit low to very low permeability, which limits the flow of groundwater, although small aquifers may exist in the superficial levels. The bearing capacity of these materials is usually favourable for conventional shallow foundations, provided that proper levelling is carried out and any potential block movements or structural discontinuities are ruled out. Slate and schists, although present in very low proportions, scarcely influence the overall mechanical behaviour of the ground.

Seismicity in Corcubión is classified as moderate, with 20 recorded events in the last 30 years and a maximum magnitude of 1.8, which implies a low seismic risk that usually does not condition the customary structural design. No karstic phenomena or soils with expansive tendencies are detected, since the non-clayey subsoil removes this problem. The main factor to be assessed in the geotechnical study is the low permeability and the possible presence of levels with superficial aquifers—aspects to be verified in order to correctly define the foundation solution.
