Estudio geotécnico in Vilafamés

In Vilafamés, the predominant subsoil is formed by limestones, dolomites and marbles, representing more than half of the soils in the municipality. These materials offer a notable bearing capacity, suitable for most direct foundation systems. Sandstones, conglomerates and flysch occur occasionally, and they also present good mechanical characteristics. Compacted gravels and sands, although less frequent, also provide excellent conditions for founding. Fine ground and hard clays are not extensive and, in general, do not represent critical constraints. However, the presence of very permeable aquifers implies that the groundwater level may be a factor to consider in the design of deep foundations.

Seismic activity in Vilafamés is moderate, with 30 events in the last 30 years and a maximum magnitude of 3.3, which entails low seismic risk for conventional building. However, there is a significant probability of the development of karst phenomena, since the dominant carbonate materials can generate cavities or underground instabilities. For this reason, it is essential to verify the possible presence of karstification before executing any foundation. The subsoil is not clayey, so the risk of swelling or expansivity is ruled out; thus, the main factor to be assessed in any geotechnical study in Vilafamés is the possible presence of karst.
