Estudio geotécnico in Dénia

In Dénia, calcareous substrates predominate, with a significant presence of limestones, dolomites and marbles that represent almost half of the soil types. These materials, of a hard and stable nature, provide good bearing capacity and are suitable for shallow foundations in most cases. However, the occasional occurrence of fine sands, silts and, in lesser proportion, soft or expansive clays requires verification of compaction and moisture conditions in order to avoid the risk of differential settlements, choosing the most competent stratum as the bearing surface.

Seismic activity in the municipality is moderate (14 events in 30 years, Mmax 2.7), with no need for specific structural measures against earthquakes of high magnitude. The presence of karstification in the calcareous substrates makes it necessary to verify the existence of cavities or underground instabilities before proceeding with foundation works, as these may compromise structural safety. In addition, the absence of extensive clayey substrates rules out the risk of expansivity as a primary conditioning factor, placing the presence of karstification as the main aspect to control in geotechnical studies in Dénia.
