Estudio geotécnico in Utebo

The ground in Utebo is characterised primarily by the presence of fine sands, silts and compact gravels, accompanied by a considerable proportion of limestones, dolomites and marbles. This diversity of materials provides generally favourable bearing capacity, compatible with shallow foundations if a competent stratum is located. However, the occasional presence of gypsum, anhydrite and salts constitutes a factor to monitor, as these materials can undergo dissolution on contact with water, generating potential voids and subsequent settlements. Extensive aquifers and high permeability should be taken into account in the design of drainage and foundation protection measures to preserve its stability.

With regard to seismicity, Utebo exhibits notable seismic activity, with 68 events in the last 30 years and a maximum magnitude reaching 4.8, which requires the application of specific design criteria for earthquake-resistant structural design in new-build projects. The substratum does not contain expansive clays, ruling out the risk of expansivity. In conclusion, although the seismic situation and the possible dissolution of salts and gypsum are key technical constraints, the permeable nature and the overall stability of the ground favour construction potential, provided that both aspects are carefully assessed in the geotechnical study.
