Estudio geotécnico in Quijorna

In Quijorna, the predominant subsoil is composed of granite, gneiss and other igneous rocks, accompanied by significant proportions of sandstones and conglomerates. In most cases, these materials exhibit high bearing capacity and stable behaviour under loads, which favours the use of shallow direct foundations in many instances. However, the occasional presence of slates and schists, with more variable mechanical behaviour, must be verified during the geotechnical study in order to determine the uniformity of the subsoil and the suitability of the foundation type to be used.

With regard to additional geotechnical risks, Quijorna shows very low seismicity, with only 5 events over 30 years and a maximum magnitude of 3, so the structural seismic analysis is not a significant constraint in the area. The absence of clayey subsoils rules out the risk of expansivity, and there are also no factors linked to karst or the presence of gypsum that would involve dissolution processes. The main constraint for the geotechnical study in Quijorna will therefore be to check the homogeneity of the bedrock and identify areas with possible localised mechanical alterations.
