Estudio geotécnico in Brihuega

In Brihuega, the geological substrate is overwhelmingly dominated by limestones, dolomites and marbles, materials that provide a high and homogeneous bearing capacity. This lithological composition favours direct shallow foundation solutions on competent bedrock, although the occasional presence of gypsum, anhydrite and salts introduces a dissolution risk that must be carefully monitored, particularly for deep foundations or heavy structures. Sections with sandstones and conglomerates, which are less frequent, also provide good support, but they may show localised changes in strength.

The seismicity in the Brihuega area is considered very low, with only 9 recorded events over the last 30 years and a maximum magnitude of 2.3, so it does not represent a relevant structural constraint. Nevertheless, the existence of karst-related phenomena associated with the limestones requires thorough verification of the possible presence of cavities or dissolution processes before building, as these may compromise the stability of the supporting ground. As the substrate is non-clayey, the risk of expansiveness is ruled out, with karst presence being the main factor to assess in any geotechnical study in the municipality.
