Estudio geotécnico in Tavernes de la Valldigna

In Tavernes de la Valldigna, the subsoil is mainly dominated by compact gravel and sand, which provides a high bearing capacity and generally favours the selection of shallow foundations. More locally, hard materials such as limestones, dolomites and marbles appear, as well as sequences of sandstones, conglomerates and flysch, broadening the foundation-solution options depending on the specific site. The occasional presence of gypsum, anhydrite and salts introduces a risk of dissolution, which may affect the integrity of the ground, particularly in areas with high permeability due to the region’s very productive and extensive aquifers.

Seismic activity in the municipality is very low, with only 3 recorded events in the last 30 years and a low maximum magnitude, so seismicity does not represent a relevant constraint for structural design. In addition, the non-clayey subsoil makes it possible to rule out the risk of harmful expansivity for buildings. However, kinematic activity associated with carbonate formations may exist in the area, which means a detailed verification of karstification processes must be carried out prior to the execution of the foundations. Thus, the main geotechnical constraint in Tavernes de la Valldigna is the possible presence of karst cavities and dissolution processes, especially in limestone areas and where gypsum is present.
