Geotechnical study in Aldeadávila de la Ribera

In Aldeadávila de la Ribera, the ground is dominated by slates and schists, together with a significant presence of granite, gneiss and other igneous rocks. This rocky substratum is widely recognised for its high bearing capacity and stability—factors that make it easier to choose shallow, direct foundations. The low permeability characteristic of these formations minimises risks associated with movements of groundwater, although it is important to assess the presence of water bodies in the vicinity of the works on a spot basis.

Seismic activity in the municipality is very low, with only 2 events over 30 years and a maximum magnitude of 1.7, so it does not constitute a constraint for structural design. Given the non-clayey nature of the substratum, the presence of risks from expansive soils is ruled out. The main geotechnical constraint in the area is the local variability in the depth and composition of the rocks, making it essential to carry out a detailed geotechnical study to verify the uniformity and fracturing of the substratum in the plot of interest.
