Estudio geotécnico in Valverde del Fresno

In Valverde del Fresno, soils formed by slates and schists predominate, accompanied to a lesser extent by granite, gneiss and other igneous rocks. These lithologies give the ground good bearing capacity, which favours the execution of shallow foundations, provided that support is avoided on fine sand and silt layers, which are present only occasionally. The overall low permeability of these materials limits the risk of internal erosion and promotes foundation stability, although shallow aquifers may form at certain elevated points, which must be taken into account for groundwater level monitoring.

Seismicity in the municipality is appreciable due to the occurrence of 56 events in the last 30 years, although the maximum magnitude (Mmax 3.1) indicates a low intensity, so it does not represent a significant requirement for conventional structural design. As the substratum is not clayey, it rules out the risk of expansivity, facilitating the selection of conventional foundation solutions, as the main limiting factor in this setting is the load-bearing behaviour of the predominant rock materials.
