Estudio geotécnico in Sabiñánigo

In Sabiñánigo, hard materials predominate, such as limestones, dolomites and marbles, accompanied by sandstones, conglomerates and flysch in significant proportions. These lithologies provide a stable substrate with good bearing capacities for the foundations of new buildings, although the occasional presence of fine sands, silts, shales or schists means that the plot must be accurately investigated to avoid areas of lower competence. The reduced permeability of these formations may favour the presence of confined or superficial aquifers, which must also be assessed during the geotechnical study.

The area shows moderate seismicity, with 30 recorded events over the last three decades and a maximum magnitude of 2.9, suggesting a low but not negligible seismic risk. However, the main geotechnical constraint in Sabiñánigo is the karst potential, typical of calcareous and dolomitic ground, so it is essential to carry out the appropriate checks to rule out cavities or dissolution before defining the foundation solution. For its part, the non-clayey substrate eliminates concern about expansive soils in this municipality.
