Estudio geotécnico in Alcorisa

In Alcorisa, soils formed by gypsum, anhydrite and salts stand out, accounting for approximately 44% of the substrate, occasionally accompanied by limestones and dolomites, as well as sandstones and conglomerates. The gypsum-bearing materials present risks of dissolution, which can affect the stability and bearing capacity of foundations. Due to the low permeability of these formations, it is essential to carry out a detailed geotechnical study to identify safe support zones and avoid possible differential settlements in the ground.

Seismicity in Alcorisa is moderate, with 13 events in the last 30 years and a maximum recorded magnitude of 2.1, so its impact on structural design is limited. Given the geological setting, the presence of karst associated with gypsum and limestones requires prior verification of the existence of cavities before any foundation work. In addition, the non-clayey substrate removes the risk of expansivity. The main precaution to consider in the area is related to dissolution phenomena and possible sinkholes due to the soluble nature of the predominant material.
