Estudio geotécnico in Sobradiel

In Sobradiel, the geotechnical subsoil is dominated by fine sands and silts, alongside a significant presence of limestones, dolomites and marbles. These materials exhibit good bearing capacity in compacted phases, although silt-bearing layers may show a certain degree of compressibility. The presence of compact gravel and sand is positive for supporting shallow foundations, whereas the occasional appearance of gypsum, anhydrite and salts introduces a dissolution risk that must be assessed before defining the foundation type and depth. The area shows extensive permeability, which favours drainage but requires controlling the potential impact on projects in relation to the underlying aquifers.

Seismic activity in Sobradiel is considered notable, with 68 events over 30 years and a maximum recorded magnitude of 4,8; consequently, seismicity must be incorporated into the structural design criteria. The risk of expansiveness is ruled out, since the subsoil is not clayey, and the absence of karst simplifies the underground characterisation. The main geotechnical factor to take into account is the interaction between soils of diverse nature and the possible dissolution of gypsum and salts, conditioning the choice of the most suitable foundation system according to the exact location of the ground.
