Estudio geotécnico in Villanueva de Córdoba

In Villanueva de Córdoba, granitic soils, gneisses and other igneous rocks predominate, making up more than 60% of the substrate, followed by the frequent presence of slates and schists. These materials offer a very good bearing capacity for foundations, generally allowing the adoption of direct and shallow solutions. The low permeability of these formations limits water infiltration, although shallow, surface-type aquifers may occur, which is an aspect to bear in mind during excavations.

Local seismic activity is moderate, with 35 recorded events over 30 years and a low maximum magnitude (Mmax 2.1), meaning that seismic aspects do not significantly influence structural design. The substrate, fundamentally non-clayey, rules out the risk of expansivity, and the absence of karst eliminates concerns associated with collapse due to dissolution. The main constraint for the geotechnical study in Villanueva de Córdoba is related to the accurate characterisation of the weathering and fracturing of the rocks, in order to define the optimum foundation depth.
