Estudio geotécnico in Jamilena

In Jamilena, formations of limestones, dolomites and marbles predominate, which implies a solid substrate with good bearing capacity for foundations, although the occasional presence of layers of sandstones, conglomerates, flysch and overconsolidated clays may introduce some local heterogeneity into the geotechnical profiles. Given the generally low permeability of these materials, the risks of differential settlement due to moisture are reduced, although there may be shallow aquifers that must be checked depending on the site. Fine sands and silts appear only occasionally and rarely condition direct bearing, but it is essential to avoid, as a foundation level, any area where loosely cemented sandy horizons are detected.

Local seismicity is classified as high, with around 200 events over 30 years, although the maximum magnitude recorded (Mmax 4.4) does not exceed the threshold specified for special structural requirements, so the seismic risk is relevant but moderate within the applicable regulations. There is a presence of PREDOMINANT EXPANSIVE CLAYS in some areas, which represents a significant geotechnical risk and must be studied in particular detail regarding the potential for swelling and shrinkage. In addition, the calcareous nature of the soil requires verification of karstification risks before carrying out the foundation. The main constraint in the area lies in the potential expansivity of the clays, together with the necessary assessment of karst cavities.
