Geotechnical study in El Pont de Vilomara i Rocafort

In El Pont de Vilomara i Rocafort, deposits of fine sands and silts predominate. These materials usually exhibit variable bearing capacity depending on their degree of compaction and moisture content. This type of soil requires careful assessment in order to determine its behaviour under load, since the formations present tend to have very low permeability. The occasional presence of shallow aquifers should be taken into account, particularly when defining the optimal depth and foundation type, considering possible changes in the groundwater table.

Seismic activity in the municipality is low, with only 5 events over 30 years and a maximum recorded magnitude of 1.6, which places seismicity at a very low level with no implications for the usual structural design. Although expansive clays occur in a subordinate position or in climatic zones without an important deficit, their direct impact on foundation stability is often limited; however, it is advisable to identify their specific location on each plot. The priority constraint for carrying out a geotechnical study in this area will be to accurately characterise the variability of sands and silts, as well as potential changes in ground moisture.
