Estudio geotécnico in Suances

In Suances, the predominant geological substrate is composed of limestones, dolomites and marbles, rock materials of high strength but prone to the development of karstic voids. These materials provide good bearing capacity for shallow or semi-deep foundations; however, the possible presence of hidden cavities requires carrying out a detailed geotechnical study to rule out differential settlements. The lower layers of fine sands, silts, compact sandstones and gravels introduce local variability, but they do not significantly affect the foundation design except in very specific areas where they may occur as isolated packages.

The seismicity in Suances is classified as notable, with 145 events over 30 years and a maximum magnitude of 4, which implies that seismic actions must be considered in structural projects, although it does not reach the most restrictive levels. The main limiting factor is marked by the risk of karst processes; it is essential to verify the absence of cavities and the stability of the ground before proposing any foundation. Since the substrate is non-clayey, the risk of expansivity is ruled out, concentrating the main focus of geotechnical attention on controlling and verifying the karst phenomenon.
