Estudio geotécnico in Vilanova del Vallès

In Vilanova del Vallès, the subsoil is made up mainly of granite, gneiss and other igneous rocks, with a significant representation of 50%. These materials provide excellent bearing capacity and offer stable conditions for shallow foundations, provided that the competent rock level is reached. Dense gravels and sands are also common, contributing good strength parameters. Fine sands and silts appear in specific areas and may show a certain degree of compressibility, although they are not predominant. It is relevant to note the low permeability of most of these formations, although small aquifers may exist at the surface level.

The seismicity recorded in the area is very low, with only 1 event in 30 years and a maximum magnitude of 2.5, which does not pose a concern for structural design. As this is a non-clayey substrate, the risk of expansiveness is ruled out, making it easier to choose conventional foundation solutions. In summary, the main factors for the geotechnical study in Vilanova del Vallès focus on the local characterisation of the mixed materials and the accurate identification of the rock level in order to optimise the foundation.
