Estudio geotécnico in Sant Vicenç de Torelló

In Sant Vicenç de Torelló, the subsoil is composed mainly of white or soft expansive clays, together with a significant proportion of sandstones, conglomerates and flysch. The dominant presence of clayey materials implies a bearing capacity that may be variable and points of low strength, although the presence of detrital materials such as sandstones and conglomerates locally improves the conditions for founding. The low overall permeability favours stability, although it may require attention in the event of shallow aquifers to avoid moisture-related problems in the foundation.

The seismicity in the municipality is very low, with only 5 events in the last 30 years and a maximum value (Mmax) of 1.6, so the seismic risk is practically negligible. Although clays predominate, the non-clayey subsoil rules out the risk of significant expansivity. The main limiting factor will be related to the distribution of the materials and areas with a higher presence of soft clays, paying particular attention to the bearing level chosen for foundations.
