Geotechnical study in Morata de Jalón

In Morata de Jalón, formations of slates and schists predominate, followed by sandstones and conglomerates, which gives the ground a medium to high bearing capacity and favours shallow foundations, although the high degree of fracturing may require local reinstatements or a suitable distribution of loads. The occasional presence of gypsum, anhydrite and salts is an additional factor to consider due to the possible risk of dissolution and subsidence, while the levels of fine sands and silts should be avoided as direct bearing strata because of their limited strength and compressibility.

From a geotechnical perspective, the seismicity is notable but of low maximum magnitude (66 events/30 years, Mmax 2.8), which implies standard structural control without extraordinary requirements. Since the substrate is non-clayey, the risk of expansivity is ruled out as a conditioning factor. It is essential to verify the possible presence of karstification in limestones and gypsum before defining the foundation solution, as the existence of cavities or conduits may compromise structural stability. In short, the main conditioning factor of the geotechnical study in Morata de Jalón lies in the potential occurrence of karst phenomena and the presence of gypsum, which require special prior analysis before the works are carried out.
