Estudio geotécnico in Ledesma

In Ledesma, the subsoil is dominated by granite, gneiss and other igneous rocks, materials with high bearing capacity and great mechanical strength. Slate, schist and occasionally sandstone or conglomerates may appear in some areas, but their presence usually does not severely limit the possibilities for direct foundation. Detrital formations of compact gravels and sands, although less frequent, also provide favourable behaviour for shallow foundations, provided that any saturated area or one close to water bodies is avoided. The generally low permeability of the ground limits infiltration, which contributes to the hydraulic stability of the foundations.

Seismic activity in the municipality is very low, with only about one recorded event every thirty years and a low maximum magnitude, which means that the seismic requirements for structural design can be considered minimal. The absence of karst rules out risks associated with underground cavities, and the non-clayey composition of the subsoil eliminates the possibility of expansivity problems. In conclusion, the determining factor for the geotechnical study in Ledesma is to ensure an adequate characterisation of the quality of the rock mass and to identify specific sectors with possible near-surface aquifers.
