Estudio geotécnico in Viladecavalls

In Viladecavalls, sandstones, conglomerates and flysch predominate, accompanied to a lesser extent by shales and schists. These materials, present in almost 90% of the municipality, provide a generally competent foundation base, with good bearing capacity and predictable behaviour under structural loads. Thanks to their lithological nature, stability is ensured provided that projects take into account the low permeability and the possible presence of aquifers at depth, which may condition the management of groundwater and the excavability.

The seismic activity recorded in the area is very low, with only 6 events over 30 years and a low maximum magnitude (Mmax 2.6), so seismicity does not condition structural designs. Since the substrate is not clayey, the risk of expansiveness is ruled out, facilitating the design and execution of foundations. The main aspect to consider in Viladecavalls is controlling the water table level and infiltration, given the low permeability of the dominant soils.
