Estudio geotécnico in Vilasantar

In Vilasantar, the dominant geological substrata are made up of sandstones, conglomerates and flysch in a significant majority, followed by shales and schists. These materials generally exhibit good strength and stability, providing an adequate bearing capacity for conventional foundations. Although the formations are mostly impermeable or of low permeability, they may present localised shallow aquifers; therefore, it is advisable to analyse possible groundwater pressures when designing the foundation.

Seismicity in Vilasantar is very low, with only 2 events observed over 30 years and a maximum recorded magnitude of 1.9, which practically rules out any influence of seismic loads on structural design. The absence of clayey substrata eliminates the risk of expansivity. Therefore, the main constraint in the geotechnical study is identifying the level of any possible shallow aquifer, without there being significant instability risks associated with karst or expansivity.
