Estudio geotécnico in Bescanó

The environment of Bescanó is characterised fundamentally by the presence of slates and schists, which account for 75% of the subsoil, providing a competent and normally uniform substrate in terms of bearing capacity, with low deformability. To a secondary extent, igneous rocks such as granite and gneiss crop out, as well as sands and silts in smaller proportions, and some compact gravel deposits located locally. This composition, largely made up of hard materials with low permeability, usually makes it easier to adopt conventional shallow foundations, provided that no levels of loose sands or silts emerge at depth.

Seismic activity in Bescanó is very low, with only 8 recorded events over 30 years and a maximum magnitude of 2.8, which implies a very low seismic risk for geotechnical design. The absence of clays in the substrate rules out concerns related to soil expansiveness, and the karst phenomenon does not present itself as a factor to consider. Therefore, the main technical condition for the geotechnical study in the area is associated with verifying the continuity and strength of the schists and slates at depth, as well as identifying any eventual loose granular zones.
