Estudio geotécnico in Leiro

In the municipality of Leiro, the ground is dominated mainly by sandstones, conglomerates and flysch, followed by shales and schists, while the presence of water bodies is very scarce. These materials often provide adequate bearing capacity for conventional foundations, although their low permeability may locally favour the development of shallow aquifers. The firm, low-deformability nature of the subsoil provides stable conditions for most projects, limiting the risk of significant differential settlements, provided that areas with soft deposits near water bodies are avoided.

Seismic activity in Leiro is moderate, with 10 recorded events over the last 30 years and a maximum magnitude of 2.4, which implies minimal seismic risks for buildings. No karstification is observed in the area and the subsoil is not clayey in nature, ruling out risks associated with expansive soils. The main geotechnical constraint for the municipality lies in the correct identification of the location of shallow aquifers and in assessing the integrity of the rock in order to optimise foundation design.
