Estudio geotécnico in Bell-lloc d'Urgell

In Bell-lloc d'Urgell, the predominant substrate is made up mainly of compact gravels and sands, which represent around 69% of the soils and are very common in the area. Sandstones, conglomerates and flysch are also present to a lesser extent. These materials generally provide good bearing capacity, allowing direct foundation solutions to be considered, although the consolidation and specific characteristics must be confirmed through a detailed geotechnical study for each case. It is important to note that the overall permeability is low, although there may be shallow water storages in certain layers, which can partially affect the foundation.

The seismicity recorded in this municipality is very low, with just three events over thirty years and a maximum magnitude of 2.5, which means that seismic risk is not a relevant constraint in structural design. Since the substratum is not clayey, the geotechnical risk associated with expansive soils is ruled out. In conclusion, the main constraint for the geotechnical study in Bell-lloc d'Urgell lies in the detailed characterisation of the gravels and sands to ensure their correct suitability as a supporting base, as well as in the verification of the shallow groundwater table, depending on the particular case.
