Geotechnical study in Vilobí del Penedès

In Vilobí del Penedès, compact gravels and sands predominate, occurring in approximately 75% of the soils. This enables a good bearing capacity and favours safety in shallow foundations. Less commonly, sandstone, conglomerates and flysch are also found, as well as certain outcrops of limestones and dolomites. Owing to their compactness and nature, these subsoils make it possible to design direct foundations without any significant difficulties, although the eventual presence of aquifers at depth must be taken into account in detailed studies.

Seismicity in the municipality is very low, with only two recorded events over the last thirty years and a maximum magnitude (Mmax) of 1.6, so the seismic influence on structures is minimal. Since the subsoil is not clayey, the risk of expansivity is ruled out, minimising the secondary problems associated with foundation stability. In conclusion, the dominant geotechnical condition in Vilobí del Penedès is favourable for construction, highlighting in particular the ground’s bearing quality and the low level of seismic activity.
