Estudio geotécnico in Sax

In Sax, the soils are mainly composed of sandstones, conglomerates and flysch, with a significant presence of fine sands and silts. These lithologies generally offer good performance from a geotechnical point of view and usually provide a medium to high bearing capacity for shallow foundations, provided that the thicknesses of fine sands and silts are not excessive or saturated. In areas of limestones, dolomites and marbles, although less frequent, a robust foundation can be obtained; however, it is essential to study the possible influence of gypsum, anhydrite and salts, occasional in the municipality, due to their potential for dissolution which may compromise long-term stability. It is crucial to avoid bearing the foundation on loose horizons or disintegrated materials.

The recorded seismicity in Sax is very low, with a low maximum magnitude (Mmax 3), so this factor scarcely affects the structural design from the seismic point of view. The non-clayey bedrock rules out expansiveness-related risks, which provides greater security regarding the volumetric stability of the materials. However, the presence of karst in areas with carbonate formations must be verified, as the existence of underground cavities or dissolution processes can affect, decisively, the feasibility of the foundations. In conclusion, the main constraint for any geotechnical study in Sax lies in the need to investigate karst-related phenomena and associated risks arising from the presence of soluble salts.
