Estudio geotécnico in Formentera del Segura

In Formentera del Segura, the subsoil is predominantly formed by fine sands and silts, which represent the vast majority of the materials present. These lithologies exhibit limited bearing capacity, making detailed geotechnical studies essential to ensure safe foundations. The infrequent presence of limestones, dolomites and marbles implies that hard materials have little impact, which rarely improves the natural load-bearing capacity. In addition, extensive local aquifers with moderate permeability and production require particular attention during foundation execution due to the possible rise of the water table and its effect on ground stability.

The area shows very low seismicity, with only about three notable events in the last three decades and a maximum magnitude of 3.3; therefore, there is no special requirement for the seismic design of structures. No karstification phenomena have been detected in the municipality, and the substratum contains no expansive clays, ruling out the risk of soil expansivity for the foundation. The main geotechnical constraint thus lies in the physical characteristics of the sandy and silty deposits and their response to changes in the water table level, which makes it essential to correctly characterise the bearing capacity and the potential settlements of the ground before any construction development.
