Estudio geotécnico in Cassà de la Selva

In Cassà de la Selva, the dominant substrate is mainly composed of compact gravels and sands, as well as granites and gneisses, which represent the greater part of the ground in the area. These formations exhibit good mechanical characteristics and an adequate bearing capacity for most foundations, facilitating straightforward, shallow solutions in many cases. The occasional presence of sandstones, conglomerates and slate-like materials increases local heterogeneity, but in general it does not constitute a significant negative constraint for the design of structural supports.

Seismicity in the municipality is moderate, with a record of 10 events in the last 30 years and a maximum magnitude of 3, which implies that the level of seismic risk is low and does not decisively condition structural design. In addition, the non-clayey substrate rules out the presence of expansive soils and, therefore, eliminates this as a limiting factor when carrying out foundations. The main aspect to be assessed when undertaking a geotechnical study in Cassà de la Selva will be the correct identification of the lithology present at the specific intervention point in order to select the optimum foundation.
