Estudio geotécnico in Elche de la Sierra

In Elche de la Sierra, the predominant substrate is made up of limestones, dolomites and marbles—highly competent materials that provide a notable bearing capacity, which is favourable for most shallow and deep foundations. The occasional presence of sands, silts, sandstones and, to a lesser extent, gypsum, anhydrite and salts may locally alter the behaviour, particularly with regard to water seepage and possible dissolution problems in areas with gypsum. The aquifers in the area show high permeability, which entails the need to assess the influence of the groundwater table level and the possible corrosivity on buried elements.

Regional seismicity is very low, with maximum values (Mmax 2.7) that do not represent a significant constraint in the structural design of buildings. However, the existence of karst processes associated with the calcareous formations makes it essential to verify cavities or possible subsidence before defining the foundation. In addition, the fact that the subsoil is not clayey rules out any risk of ground expansivity, leaving control of the karst as an essential factor in the geotechnical studies of the area.
