Estudio geotécnico in Villanueva de la Concepción

In Villanueva de la Concepción, the predominant materials in the subsoil are slates and schists, accompanied by sandstones, conglomerates and flysch, whereas calcareous formations, dolomites and marbles are less common. These lithologies generally provide good stability and an adequate bearing capacity for most buildings. However, the characteristic impermeability of these strata can affect the management of groundwater and surface water, making it essential to carry out a detailed analysis to define the most suitable foundation, particularly in areas of local aquifers.

The municipality’s seismic activity is moderate, with a record of 19 events over 30 years and a maximum magnitude of 3.9, which implies considering seismic design criteria, although without strict requirements. Given the occasional presence of carbonated materials such as limestones and dolomites, it is necessary to check for karst processes before carrying out the foundations, as they may condition the stability of the structure. The non-argillaceous substrate eliminates the risk of expansiveness, highlighting as the main control factor the possible presence of karstic cavities.
