Estudio geotécnico in Puigpunyent

In Puigpunyent, the ground is characterised predominantly by the presence of limestones, dolomites and marbles—rocky materials that generally provide a high bearing capacity for the foundations of new buildings. However, the significant presence of gypsum, anhydrite and salts introduces a risk factor associated with the dissolution of these materials, which may compromise the stability of shallow and deep foundations. Very fine soils such as sands and silts are rare and have little influence on the overall bearing capacity of the area.

Historical seismic activity is considered moderate, with 24 events in the last 30 years and a maximum magnitude of 3.2, which does not constitute a critical constraint for structural design. It is nevertheless essential to carry out a specific verification of karst development before planning any foundation in the municipality, since the presence of karst can induce unexpected voids or sinkholes. The non-clayey substrate rules out risks of expansiveness; the potential for dissolution and karst are the main factors to analyse in the geotechnical studies of the area.
