Estudio geotécnico in Ciutadella of Menorca

In Ciutadella de Menorca, the substrate is predominantly made up of limestones, dolomites and marbles, along with the occasional presence of sandstones and conglomerates. These rock materials, generally of high quality, provide a notably favourable bearing capacity for the direct foundation of buildings, although their local discontinuity requires confirming the homogeneity of the stratum through a precise geotechnical study. The existence of extensive aquifers and moderate permeability make it necessary to assess the groundwater level and its possible influence on deep interventions.

Seismic activity in the municipality is moderate, with 24 recorded events over 30 years and a maximum magnitude of 3.2, which implies a low seismic risk for conventional structural design. However, since the substrate consists mainly of limestones and dolomites, the development of karst phenomena is a real possibility that must be verified before carrying out any foundation works, as it can cause voids and subsidence. In addition, the substrate does not contain expansive clays, ruling out expansivity risks. The main limiting factor in Ciutadella de Menorca will be the potential presence of active or ancient karst processes beneath the study area.
