Geotechnical study in Sallent

In the municipal term of Sallent, substrates of sandstone, conglomerates and flysch predominate, accompanied to a lesser extent by gravel and compact sands. These lithologies, generally compact and of coherent formation, provide good conditions for bearing capacity for traditional foundations, although the low permeability may require studying possible accumulations of groundwater at certain levels, particularly in areas in contact with shallow aquifers. The soils of the municipality make it possible to propose shallow foundations except for local exceptions, facilitating technically and economically efficient solutions.

Seismicity in Sallent is very low, with only 1 recorded event in 30 years and a maximum magnitude of 3, so the seismic risk is practically negligible in geotechnical design. The absence of karst and the non-clayey nature of the subsoil also rule out the influence of expansive processes. Overall, the geotechnical conditions in Sallent are favourable, with relative impermeability and any possible pockets of water being the main aspects to check during the geotechnical study phase.
