Estudio geotécnico in Belalcázar

In Belalcázar, the geological substrate is predominantly dominated by slates and schists, with a secondary presence of granite, gneiss and other igneous rocks. Locally, compact gravels and sands are also found, as well as small areas of overconsolidated clays and marls. These lithologies, in particular the slates and schists, tend to provide a moderate bearing capacity and low deformability, which favours conventional shallow foundations in most cases. The low overall permeability of these materials implies favourable behaviour with regard to infiltration problems, although there may be associated shallow aquifers in specific areas that will need to be studied in order to prevent situations involving undermining or soil washout.

Seismic activity in Belalcázar is very low, with barely one recorded event in the last 30 years and a maximum magnitude of 1.5, so it does not represent a relevant constraint for structural design. There are no signs of karstic processes or significant expansiveness, given the predominance of non-clayey materials in the substrate. As a main conclusion, the lithological typology and the low level of seismicity mean that the appropriate characterisation of the degree of fracturing of the materials and the possible presence of local aquifers are among the key aspects to control during the geotechnical study and the definition of the foundation solutions.
