Estudio geotécnico in Bolbaite

In Bolbaite, the ground is dominated by limestones, dolomites and marbles, which account for more than 80% of the substrate, together with small fractions of fine sands, silts and a point-like presence of gypsum, anhydrite and salts. These materials typically provide an excellent bearing capacity for shallow and deep foundations. However, the existence of gypsum and salts entails some risk of dissolution, although in limited proportions. The low presence of soft materials such as silts or sands, and the absence of muds or peats, mean that the choice of support level, in geotechnical terms, is relatively safe.

Seismicity in Bolbaite is very low, with barely any events recorded in the last 30 years and a low maximum magnitude (Mmax 1.6), which implies that it does not represent a relevant threat to design. Since the substrate is not clayey, it rules out expansive risks associated with clays. However, the possible presence of karstification in the limestones and dolomites requires a detailed verification through a geotechnical investigation before any foundation is built, as the existence of voids or dissolutions could be the main factor conditioning the geotechnical study in this municipality.
