Estudio geotécnico in La Vall d'en Bas

In La Vall d'en Bas, soils formed by sandstones, conglomerates and flysch predominate; these geological materials provide good resistance and stability for building projects. These lithologies exhibit low permeability, which usually limits water infiltration and favours ground stability. The bearing capacity is usually adequate, although it will be necessary to assess the compactness and the possible development of shallow aquifers at some points. For the foundation, direct systems can generally be used, although it is always advisable to confirm the homogeneity of the substrate during the geotechnical survey.

The seismic activity recorded in the municipality is very low, with only 2 events recorded and a low maximum magnitude (Mmax 1.6), ruling out seismicity as a relevant factor in structural design. There are also no signs of karst processes or risks associated with expansivity, since the non-clayey substrate eliminates this concern. Thus, the main geotechnical constraint to take into account will be the precise characterisation of the lithological substrate in the specific area of intervention.
