Estudio geotécnico in Els Hostalets de Pierola

In Els Hostalets de Pierola, soils of compact gravels and sands predominate, together with sandstones, conglomerates and flysch. These formations generally show good bearing capacity and offer suitable characteristics for shallow foundations, owing both to their compactness and to the low risk of differential settlement. The low permeability of these materials limits the presence of deep groundwater, although it is possible to find shallow aquifers in some areas, which requires some attention during foundation design to avoid dampness-related problems.

The municipality’s seismicity is very low, with only 5 recorded events over 30 years and a maximum magnitude of 1.6, so it does not constitute a relevant constraint for structural design. The non-clayey substrate rules out expansivity, eliminating the risk of swelling or shrinkage in the supporting soils. Thus, the main geotechnical conditions favour the safety and stability of foundations in the area.
