Estudio geotécnico in Sacedón

In Sacedón, water-bearing formations predominate, followed by outcrops of limestones, dolomites and marbles, and to a lesser extent gypsums, anhydrite and salts. These carbonate materials habitually provide good bearing capacity, although the occasional presence of gypsums and soluble materials can adversely affect stability if they are found within the foundation area. The low frequency of expansive clays minimises the risks associated with volumetric movements, so most projects may consider direct foundation solutions on the rocky substratum, provided that levels of gypsum and materials susceptible to dissolution are avoided.

From the seismic standpoint, Sacedón shows very low activity, with only 5 recorded events over 30 years and a maximum magnitude of 1.9, which makes it possible to rule out seismicity as a relevant factor in structural design. However, the significant presence of calcareous and dolomitic materials makes it necessary to verify the existence of karst features before founding, as the industry recognises the potential development of associated cavities. The most significant constraint for geotechnical studies in this municipality is the assessment and control of karst risk, and, to a lesser extent, the possible discontinuous presence of gypsums and salts that could trigger dissolution processes.
