Estudio geotécnico in Gorliz

In Gorliz, the predominant soils largely correspond to sandstones, conglomerates and flysch, accompanied by a notable presence of limestones, dolomites, marbles and beds of fine sands and silts. This geological setting generally provides good bearing capacity, particularly in the strata of a more rock-like nature, favouring the use of shallow foundations provided that the homogeneity of the ground is ensured. It is important to identify the presence of the finer deposits, since the sand and silt horizons, despite being frequent, may show localised variations in bearing capacity and may require additional checks to optimise the foundation design.

Seismicity in Gorliz is considered notable, with 94 events over 30 years though without exceeding critical magnitudes (Mmax 3.7), meaning it is an aspect to be considered without requiring exceptional structural requirements. The expansiveness recognised through the subordinate presence of clays, combined with climatic conditions that limit expansive activity, implies a moderate and localised risk in specific areas: these sectors should be assessed on a case-by-case basis during the geotechnical study. As the main constraint on the site, substrate heterogeneity stands out, along with the possible localisation of fine layers or low competency levels that could modify the bearing characteristics that were predicted.
