Estudio geotécnico in Cehegín

In Cehegín, the predominant geological substrate is composed mainly of limestones, dolomites and marbles, which provides soils with high bearing capacity, favouring direct or shallow foundations across much of the area. The frequent presence of fine sands and silts should also be taken into account, as these materials may show a certain degree of compressibility. It is relevant to note the occasional presence of deltaic muds and peats—materials that have low strength and high compressibility—so they are not recommended as a bearing level for foundations and must be strictly avoided during the execution of works.

Seismicity in Cehegín is moderate, with around 29 recorded events in the last 30 years and a maximum magnitude of less than 4.5; therefore, seismic influence on buildings is limited and may not be determining in most projects. The non-clayey substrate rules out the risk of expansivity. However, given the karstic nature of the limestones and dolomites, it is essential to verify the presence of cavities or instabilities associated with karst before defining and carrying out the foundation. Therefore, the main geotechnical constraint is the need to identify and assess potential karstic zones.
