Estudio geotécnico in Monforte de Lemos

In Monforte de Lemos, soils composed of sandstones, conglomerates and flysch predominate, as well as slates and schists; these materials provide good bearing capacity in most cases. The occasional presence of compacted gravels and sands further favours stability and makes it possible to consider conventional shallow foundations, while outcrops of granite, gneiss or other igneous rocks, although less frequent, offer optimal conditions for supporting structures of a certain size. The low presence of limestones, dolomites or marbles reduces the likelihood of encountering karstified areas. The reduced permeability of these materials also implies a stable response to superficial hydrogeological changes on the ground.

From the point of view of seismic hazard, the record of only 7 events in 30 years with a maximum magnitude of 2.6 places Monforte de Lemos at a level of very low seismicity, which favours structural design without special requirements. The municipality does not present clayey strata, so the problem of expansivity is ruled out. As a result, the main constraints for the geotechnical study focus on the accurate identification of the supporting materials and the characterisation of local permeability, with no significant risks associated with seismicity, expansivity or karst.
