Estudio geotécnico in Robledo de Chavela

In Robledo de Chavela, the predominant subsoil is made up of granitic formations, gneisses and other igneous rocks, accounting for around 70% of the ground. Slate and schists are also present to a significant extent. These lithologies provide high bearing capacities for foundations, although they usually require specific excavation systems due to their high compaction and hardness. The low permeability of the ground limits infiltration, but may favour the presence of localised shallow aquifers that should be considered in the design phase.

Seismicity in the area is moderate, with 10 recorded events over 30 years and a maximum magnitude of 1.9, which reduces the seismic design requirements for structures. The substratum, as it does not contain expansive clays, rules out risks associated with volumetric movements related to moisture. In conclusion, the rocky and stable nature of the substratum is the main positive conditioning factor for decision-making in the geotechnical study of the municipality.
