Estudio geotécnico in Horche

In Horche, the predominant geotechnical subsoil is made up of limestones, dolomites and marbles, which ensures favourable mechanical properties in terms of bearing capacity for shallow or deep foundations. The sandstones and conglomerates that are also present contribute some heterogeneity, although to a lesser extent. The occasional presence of gypsum, anhydrite and salts implies a potential risk of dissolution, particularly in areas where these materials crop out, which must be carefully assessed when designing footings, piles or other structural support systems. The non-clayey subsoil rules out risks of ground expansivity.

The municipality has high seismicity, with more than 150 registered events over the last 30 years and a maximum magnitude of 4.6, so it is essential to take this parameter into account in the structural and foundation design. On the other hand, the development of karst processes in the carbonate formations requires an exhaustive check for the possible presence of cavities or galleries before proceeding with any foundation. In conclusion, the main geotechnical constraint in Horche is controlling the karst risk together with seismicity, whereas risks due to expansivity can be ruled out in this case.
