Estudio geotécnico in Segura de la Sierra

In Segura de la Sierra, carbonate materials predominate, mainly limestones, dolomites and marbles, which make up 47.54% of the subsoil and constitute the dominant substrate for foundations. These materials usually provide good bearing capacities, although their rigid and fractured nature may require a detailed study of the load distribution. Secondary materials include sandstones, conglomerates and flysch, together with the occasional presence of gypsum, anhydrite and salts, which may present risks of local dissolution. Deposits of gravels, sands and silts are very rare, which limits their incidence as directly supporting soils. In this context, accurate characterisation and in situ verification of the substrate are essential in order to select the most reliable and safe foundation solution.

Seismicity in the municipality is moderate, with 35 recorded events in the last 30 years and a maximum magnitude (Mmax) of 3.7, which implies a low technical consideration in structural design compared with more active areas. There is also a notable risk of karst development in the carbonate materials present, making it essential to carry out checks prior to foundation works to rule out cavities or associated instabilities. The presence of gypsum and salts, although only occasional, recommends assessing the risk of dissolution and its possible long-term effects. The absence of an clayey substrate rules out expansivity-related problems, establishing as the main constraints the presence of karst and the possible risk of dissolution associated with the ground type.
