Geotechnical study in Xinzo de Limia

In Xinzo de Limia, formations of sandstones, conglomerates and flysch predominate, accompanied by smaller levels of overconsolidated clays and marls, as well as slates and schists. These materials typically provide good to moderate bearing capacity, especially in areas where hard, compact materials prevail. However, the occasional presence of muds and peats of deltaic origin requires special attention, as these soils are not suitable as a supporting layer for foundations and must be avoided or treated if encountered within the project site.

Seismicity in the municipality is considered moderate, with 36 recorded events in the last 30 years and a maximum magnitude of 3.7, which implies the need for a basic analysis of seismic stability in the design, although without special structural requirements. The non-clayey substratum rules out significant expansivity risks and there are no constraints associated with karst processes. The main aspect to be verified in a geotechnical study will be the detection and treatment of soft soils of mud or peat type, always prioritising foundation solutions over the dominant hard strata.
