Estudio geotécnico in Valdés

In Valdés, the dominant geological substrate is formed by slates and schists, metamorphic materials, which implies low permeabilities and high mechanical strength. These rocks tend to offer a notable bearing capacity, facilitating conventional shallow foundation solutions if the levels of alteration or fracturing are minimal. It is important to verify the continuity of these materials and avoid placing foundations on areas with an occasional presence of groundwater, as this could alter stability conditions and increase local compressibility.

The municipality’s seismicity is very low, with only 5 events in the last 30 years and a maximum recorded magnitude of 2.7, so the seismic risk for structural design is low. However, the presence of karst phenomena in the area requires a specific ground check before carrying out any foundation works, with the aim of ruling out the existence of cavities or voids that could compromise safety. The non-clayey nature of the substrate eliminates the risk of expansiveness, meaning that the main geotechnical focus should be on the possible occurrence of karst developments in specific sectors.
