Estudio geotécnico in Elx/Elche

In Elx/Elche, fine sands and silts predominate, which determines the ground’s bearing capacity, placing it at medium-low values and requiring special attention to compaction and settlement control for the foundation. Locally, sandstone, conglomerates and flysch are also present, as well as occasional calcareous formations. These features may favour the surface accumulation of water due to low permeability, influencing the choice of the foundation system and the management of drainage.

Seismicity in Elx/Elche is moderate, with 21 events recorded over 30 years and a maximum magnitude below 4.5, so it does not pose a special requirement for structural design. However, given the occasional presence of limestone and dolomites, it is essential to verify the existence of karstic phenomena before carrying out foundations, as these could involve voids or underground cavities that would compromise stability. The non-clayey substratum rules out the risk of expansivity, leaving the main geotechnical constraint in the possible presence of cavities due to karstification and the low bearing capacity of the silty and sandy formations.
