Estudio geotécnico in Arcos de Jalón

In Arcos de Jalón, the geological substrate is dominated mainly by limestones, dolomites and marbles, accompanied by a significant presence of gypsum, anhydrite and salts, as well as occasional occurrences of sandstones, conglomerates and flysch. These materials, for the most part with low to very low permeability, provide a moderate to high bearing capacity for foundations, although special attention must be paid to areas with gypsum or salts due to the risk of dissolution, which can generate differential settlements or instabilities. The formations of gravels and sands show good mechanical behaviour, and their use for support is recommended provided that their compactness is guaranteed.

Seismic activity in the municipality is moderate, with 12 events recorded over the last three decades and a maximum magnitude of 3.6, which suggests a limited seismic risk that, nevertheless, should not be ignored when designing the structural elements. The non-clayey substrate rules out expansivity risks, but the possible existence of karstification in the carbonate and evaporitic materials requires thorough verification of voids before any foundation project, making this factor the main geotechnical constraint in the area.
