Estudio geotécnico in La Malahá

In La Malahá, the geological substrate is made up mostly of gypsum, anhydrite and salts, materials which generally have sufficient bearing capacity to support buildings, although they require detailed analysis because of their particular behaviour under loads. The impermeability of these materials leads to the presence of shallow aquifers in certain areas, which can affect the stability and design of the foundations. In addition, the high salt content implies a risk of dissolution; therefore, it is crucial to consider these factors to avoid differential settlement or stability problems in the medium and long term.

This municipality exhibits high seismic activity, with 200 recorded events in the last 30 years, although the maximum magnitude does not exceed 3.8, meaning that the structural effect is moderate but not negligible. The presence of karstification must be checked thoroughly prior to any intervention, since this phenomenon can cause cavities and unexpected ground subsidence. The possible development of expansive clays, although subordinate, suggests evaluating their presence locally; however, the main factor conditioning the geotechnical study in La Malahá remains the risk resulting from the dissolution of gypsum and salts, together with the existence of karst structures.
