Geotechnical study in Los Molinos

In the municipality of Los Molinos, the dominant substrate is made up of granite, gneiss and other igneous rocks, accounting for 100% of the materials observed in the soil studies in the area. This type of ground provides a solid and stable base, with high bearing capacity, which makes it easier to select shallow (direct) foundations for most structures. The impermeability or very low permeability associated with these materials may lead to localised superficial aquifers, but it does not constitute a relevant factor for the stability of the ground under usual structural loading.

In terms of geotechnical hazards, the Los Molinos area shows very low seismicity, with a maximum of 5 events over 30 years and a maximum magnitude of 3, which implies a minimal influence for seismic design of buildings. Since the substrate is non-clayey, the risk of expansiveness is completely ruled out, so this factor does not affect the project. Overall, the municipality’s main geotechnical advantage lies in the stability and excellent performance of its rocky substrate, which simplifies the foundation design procedures.
