Geotechnical study in La Pobla de Lillet

In La Pobla de Lillet, soils formed by sandstones, conglomerates and flysch predominate, which provides a competent ground for foundations in most cases. These lithologies usually offer good bearing capacity and stable behaviour, making them a suitable base for buildings and other infrastructure. Low near-surface permeability can favour stable conditions, although it must be verified whether there are aquifers at depth that require specific attention in some projects.

Seismic activity in the area is very low, with only about 5 events in 30 years and a maximum magnitude of 1.6, so the risk from earthquakes is practically negligible. However, since conditions are favourable for the development of karst, it is essential to check for the presence of cavities or zones of dissolution before defining the foundation. The fact that the bedrock is not clayey rules out concerns about expansiveness; therefore, potential karst development is the main factor to be studied during the geotechnical study analysis.
