Estudio geotécnico in Benifairó de la Valldigna

In Benifairó de la Valldigna, formations of limestones, dolomites and marbles predominate, providing a competent substrate and one that is generally favourable for shallow foundations. The presence of compacted gravels and sands also offers good conditions for bearing capacity and drainage. There is a low representation of expansive clays and overconsolidated stiff clays, so problems linked to deformation or differential settlement are reduced in comparison with municipalities dominated by more plastic materials.

Seismicity in the area shows moderate activity, with 27 events in the last 30 years, although with a low maximum magnitude (Mmax 3.4), so seismic risk is rather limited. There are no indications of significant expansivity, as the subsoil is not clayey, thus ruling out problems associated with that. However, since carbonated materials such as limestones and dolomites are present, it is essential to check for possible karstic voids before constructing, as these represent the main local geotechnical constraint.
