Estudio geotécnico in Migjorn Gran, Es

In Migjorn Gran, soils formed by limestones, dolomites and marbles predominate, occupying more than 90% of the territory and creating a rigid and competent substrate with good bearing capacity for shallow foundations. However, in specific areas, white or soft expansive clays may be present, although their occurrence is occasional and in the minority. Extensive aquifers and moderate ground permeability could imply variations in the saturation of the subsoil; therefore, foundation solutions must take into account possible fluctuations in the groundwater table.

Seismicity in Migjorn Gran is moderate, with 24 events over 30 years and a maximum magnitude (Mmax) of 3.2, indicating a low risk from the structural standpoint. However, given the pronounced karstic nature of the limestone and dolomitic materials, it is essential to verify the presence of cavities and voids prior to proposing any foundation solution. In this municipality, karst development is the main geotechnical constraint to consider in subsurface investigations.
