Estudio geotécnico in Moraleda de Zafayona

In Moraleda de Zafayona, fine sands and silts predominate, alongside a significant presence of limestones, dolomites and marbles. These lithologies usually provide a medium bearing capacity, suitable for most buildings, although precise characterisation of the silt fraction must be carried out to avoid compressibility-related risks. It is important to take into account the existence, albeit occasional, of muds and peats of deltaic origin; these materials present low bearing capacity and high settlement, which is why they should be avoided as a support level in foundations.

The municipality is located in an area of moderate seismicity, with 14 events over the last 30 years and a low maximum magnitude, so seismic risk is limited, although it must be verified according to the type of structure proposed. In addition, the significant presence of limestones, dolomites and marbles implies a potential risk of karstification; it is recommended to check for the presence of cavities or dissolutions before founding in order to avoid future differential settlements. The absence of an underlying clay substrate rules out expansiveness as a relevant constraint in the area, with the main geotechnical aspect to control being the possible development of karst processes beneath the planned sites.
