Estudio geotécnico in Albalate del Arzobispo

In Albalate del Arzobispo, the dominant geotechnical subsoil is formed by gypsum, anhydrite and salts, present in more than 24% of the ground, complemented by sandstones and conglomerates. These lithologies generate soils of variable resistance, presenting locally risks of dissolution associated with gypsum and salts, which can induce subsidence processes or the formation of cavities not detected at the surface. Dense gravels and sands, although less frequent, provide favourable points for foundations due to their good bearing capacity, whereas the occasional presence of fine sands and silts may limit their use as a stable support stratum. The existence of extensive high-permeability aquifers must be considered both in soil consolidation and in controlling the groundwater level during the execution of the works.

Seismic activity in the municipality is moderate, with 49 events over 30 years and a recorded maximum magnitude of 3,5; although it is not a significant threat for conventional structural design, it should not be ignored in specific projects. Verification of the karst phenomenon is essential before defining the foundation type, as gypsum and sulphate-bearing materials can undergo significant dissolution processes, increasing the risk of ground instability. Since the subsoil is not clayey, the risk of expansiveness is ruled out. In conclusion, the most relevant geotechnical constraint in Albalate del Arzobispo is the presence of gypsum formations and karst vulnerability—factors that require a detailed geotechnical study prior to any construction intervention.
