Estudio geotécnico in Navahermosa

In Navahermosa, granito, gneiss and other igneous rocks predominate as substrate, occasionally accompanied by slates, schists, sandstones and flysch. This lithological set provides high bearing capacities, allowing direct foundations in stable and compact areas. The low presence of soft materials, such as clays or hard marls, minimises the risks of deformability and compressibility under structural loads, while the generally low permeability of the formations limits inconveniences related to the migration of groundwater.

The municipality’s seismicity stands out for recording more than 150 events in the last 30 years and reaching a maximum magnitude of 5.1; these factors require structures to be designed considering seismic action. The geological setting also presents a possible development of karst cavities, so karst must be specifically verified before executing any type of foundation. The non-clayey nature of the substrate rules out expansivity as a relevant problem, with seismic activity and possible karst being the main conditioning factors for the geotechnical studies in Navahermosa.
