Estudio geotécnico in El Robledo

In El Robledo, the dominant geotechnical substrate is mainly composed of slates and schists, representing close to 95% of the area. These materials are very low permeability and tend to provide a moderate to high bearing capacity, which generally facilitates the planning of direct shallow foundations. However, the discontinuities and foliation planes inherent to the slates may require specific attention during execution to ensure the stability of the foundation.

Seismicity in El Robledo is very low, with only about 3 recorded events in the last 30 years and a maximum magnitude of 2.4, which limits the impact of additional structural requirements for this reason. The geotechnical analysis shows no presence of expansive clayey soils or karst risk, ruling out problems of expansivity or associated subsidence. Therefore, the most relevant geotechnical constraint in the municipality lies in the accurate characterisation of the existing slates and schists, especially with regard to their fracturing and compaction.
