Estudio geotécnico in Alcaraz

In Alcaraz, formations of gypsum, anhydrite and salts predominate; they make up more than half of the geological substrate and exhibit very low permeability. This type of ground implies special caution regarding the risk of dissolution, as subsidence processes or differential movements may develop in the foundations. The occasional presence of limestones, dolomites and marbles adds the possibility of karst structures, while compact sands and gravels are infrequent but, if encountered, they can provide favourable bearing levels for construction.

Seismicity in Alcaraz is moderate, with 22 events in the last 30 years and a recorded maximum magnitude of 2.6, so the risk associated with seismic movements is low. The non-clayey substrate rules out problems related to expansive soils. However, the main technical constraint is the frequent occurrence of karst zones and the presence of soluble materials, which requires thorough verification of karstification processes before designing the foundation of any structure in the area.
