Geotechnical study in Segorbe

In Segorbe, sandstone, conglomerate and flysch substrata predominate, followed by limestones, dolomites and marbles, alongside a notable presence of gypsum, anhydrite and salts. These materials often provide adequate bearing capacity for foundations, although it is essential to pay attention to the gypsum and salts due to their potential for dissolution, which can affect the stability of the ground under structural loads. The low permeability of the surface formations suggests that natural drainage is usually not high, although aquifers may exist at depth, which must be checked to rule out moisture problems in basements or foundations.

Seismic activity in the municipality is very low, with only 7 events in 30 years and a maximum magnitude (Mmax) of 2.4, which implies that seismic risk can be considered low for structural design. Nevertheless, the karstified nature of the ground requires checking for the presence of cavities before proceeding with foundation work, especially in areas with limestones and gypsum where dissolution can generate voids. Likewise, the non-clayey substrate rules out the risk of expansivity, so the main geotechnical constraint will be the possible presence of karst processes combined with soluble soils, which require a specific analysis in each building project.
