Estudio geotécnico in Casabermeja

In Casabermeja, the geological substrate is widely dominated by slate and schist, metamorphic materials that represent more than 60% of the ground. These formations tend to provide a medium bearing capacity, although it may be conditioned by planes of foliation or fracturing. Occasional areas of limestone, dolomite and marble introduce some variety in ground conditions, generally providing better bearing capacities but also requiring targeted checks of stability; meanwhile, the sandstones and conglomerates present in a smaller proportion contribute to local variability. The low inherent permeability of most of these materials means that surface ponding and shallow aquifers may be found, so hydrogeotechnical analysis is essential for the correct choice of the foundation system.

The area records moderate seismicity, with 12 events over 30 years and a maximum magnitude of less than 4. There is no relevant karstified hazard, so the integrity of the subsoil is generally considered stable with regard to natural cavities. Since non-clayey substrates predominate, expansivity problems are not expected, which improves safety against differential settlements. As the main constraint, the structural characteristics of the slates and schists, together with the possible presence of weakness planes, will be key for safe geotechnical design in Casabermeja.
