Estudio geotécnico in L'Armentera

In L'Armentera, the predominant ground comprises fine sands and silts, materials considered to have low plasticity, which results in variable bearing capacity, suitable for shallow foundations under conditions of favourable compactness. However, the occasional presence of deltaic muds and peats means that it is necessary to avoid these organic levels as a bearing stratum, as they exhibit very compressible behaviour and low mechanical strength. In general terms, it is recommended to carry out a detailed geotechnical study in order to delineate homogeneous zones and define the optimum foundation levels.

As regards seismicity, the municipality records 10 significant events over 30 years with a maximum magnitude of 1.9, which corresponds to a moderate seismic activity scenario and does not imply critical constraints for the usual structural design. The non-clayey substrate rules out the risk of expansivity, enabling conventional foundation design. The main constraint lies in identifying and excluding the levels of muds or peats when designing the foundation system, thereby ensuring the stability and durability of the structures.
