Estudio geotécnico in Toral de los Vados

In Toral de los Vados, the substrate is predominantly made up of slates and schists, characterised by low permeability and a competent response to structural loads, generally offering sufficient bearing capacity for shallow foundations, except in local cases of advanced alteration. Areas where compact gravels and sands occur can improve ease of execution and provide viable alternatives for shallow foundation design. It is important to avoid founding on masses of water, whereas the occasional proportion of sandstones and conglomerates does not constitute a significant constraint in most interventions.

The seismicity recorded in the municipality is notable, although the maximum magnitude values are low and do not imply significant seismic requirements for conventional regulatory design. Nevertheless, given the presence of karst phenomena, it is essential to verify whether cavities or dissolutions exist in the ground before proceeding with the foundations, as they represent the main local geotechnical constraint. The absence of clayey materials rules out the risk of expansivity in this environment.
