Estudio geotécnico in Valencia de Alcántara

In Valencia de Alcántara, slate and schists predominate as the substrate, which translates into soils with high compactness and moderate strength, ideal for supporting typical structural loads. Granitic and igneous formations appear occasionally, giving locally more rigid and stable sections. The low permeability of the ground limits the presence of water at depth, which is favourable for the durability of foundations, but requires attention to the surface drainage of water to prevent accumulations over the bases of the structures.

Seismicity in the municipality is classified as notable, with 56 events in the last 30 years, although the maximum recorded magnitude (Mmax 3.1) does not represent a significant risk for conventional foundation engineering. The absence of clayey soils eliminates concern regarding expansiveness, ensuring a predictable ground behaviour over time. Consequently, the main constraint for the geotechnical study in Valencia de Alcántara lies in the appropriate mechanical characterisation of the dominant metamorphic materials.
