Estudio geotécnico in Villafranca de los Caballeros

In Villafranca de los Caballeros, the geological subsoil is mostly composed of limestones, dolomites and marbles, accompanied in smaller proportions by gypsum, anhydrite and salts. These formations are known for offering good bearing capacity, which favours the stability of foundations, especially in compact, well-founded soils. The low surface permeability may allow the existence of aquifers at deeper levels, but it also requires attention during the foundation phase due to the possible presence of soluble materials. The infrequent presence of gravels, sands and igneous materials suggests the existence of locally more mechanically competent zones.

Seismic activity in the area is considered high, with 200 recorded events in the last 30 years and a maximum magnitude (Mmax) of 5.1, which makes it necessary to incorporate specific seismic requirements in structural design. In addition, the existence of soils with gypsum and salts entails a dissolution risk that may affect the stability of the ground under sustained loads. Although the presence of expansive clays is rare and the dominant subsoil is not clayey, the risk of expansivity may be considered negligible. Before any foundation is constructed, it is essential to verify the existence of karstification, as this represents the main conditioning factor in the geotechnical behaviour of the municipality.
