Estudio geotécnico in Villadiego

In Villadiego, limestones, dolomites and marbles predominate, together with a significant development of sandstones and conglomerates. This rock substratum generally provides good bearing capacity and allows stable direct foundations; however, in areas where compact gravels and sands crop out, the mechanical behaviour may vary. The presence of extensive aquifers and very permeable soils implies the need for proper treatment of groundwater in the geotechnical study, as well as preventing sudden drops in the water table during the excavation phases.

Seismic activity is very low, as 5 events have been recorded over 30 years with a maximum magnitude of 2.6, meaning that the seismic risk for structures is low. However, given the karstic nature of the carbonate materials common in the area, it is essential to investigate the presence of cavities or dissolution processes before any foundation, as these can compromise ground stability and bearing capacity. The non-clayey substratum eliminates the risk of expansivity, with the karst phenomenon being the main geotechnical condition to take into account in Villadiego.
