Estudio geotécnico in Cañada Rosal

In Cañada Rosal, the dominant material comprises fine sands and silts, which account for more than half of the soils, occasionally accompanied by limestones, dolomites and marbles. These materials, together with the presence of highly permeable aquifers, favour good drainage capacity but require detailed studies to determine bearing capacity, particularly in areas where silts or water-bearing layers are present, which can reduce ground resistance and increase differential settlement. It is essential to carry out an appropriate stratigraphic analysis prior to selecting the type of foundation, since subsoil characteristics can vary significantly over short distances.

The recorded seismic activity is very low, with only one event over three decades and a low maximum magnitude, so seismic hazard is marginal in structural design. However, the main geotechnical constraint comes from the high risk associated with the predominant expansive clays, which can cause severe problems of swelling and shrinkage in foundations. As a result, the geotechnical study in Cañada Rosal must focus primarily on assessing the ground’s expansive behaviour in order to prevent pathologies in structures.
