Estudio geotécnico in Totana

In Totana, the dominant substrate corresponds to fine sands and silts, present in almost 60% of the municipality, which implies a ground with medium or low bearing capacity depending on the local compactness. Limestones, dolomites and marbles are observed in specific locations, being occasional and associated with better conditions for shallow foundations if their fracturing is low. Due to the predominant presence of silty and sandy materials, it is essential to carry out in-situ tests to determine the groundwater table level and to avoid problems caused by differential settlement. Permeability is generally low, although there may be areas where shallow aquifers are present, which conditions the choice of foundation depth and type.

The municipality shows a notable level of seismicity, with 138 events in the last 30 years and a maximum magnitude value (Mmax) of 5.4, which means that seismic actions must be considered in the structural design of any project. Given the karstifiable nature of part of the subsoil, especially where limestones and dolomites crop out, it is a priority to verify the possible existence of cavities or instabilities associated with them before carrying out the foundation works. The absence of clayey materials rules out the risk of soil expansivity. In Totana, the main factors for any geotechnical study are significant seismicity and the potential for karst formation, which require thorough investigation prior to construction.
