Estudio geotécnico in Palazuelos de Eresma

In Palazuelos de Eresma, soils formed by slate and schists predominate, representing 93% of the subsoil and creating a geotechnical environment in which bearing capacity is usually high and homogeneous. These metamorphic materials, characterised by low permeability, favour shallow foundations directly on competent ground, unless extensive alteration has produced occasional ochreous levels. Granite, gneiss and other igneous rocks occur only very occasionally, also providing good bearing capacities but requiring additional checks in the event of deep foundations or anchors.

The area is characterised by high seismicity, with 200 events recorded over 30 years and a maximum magnitude of 4.7, which implies the need to incorporate seismic-resilient criteria into structural design. Since the subsoil does not contain significant clay fractions, the risk of expansivity is ruled out, allowing for greater predictability in ground behaviour. The main geotechnical constraint for this municipality lies in considering seismic load during the analysis and execution phases of the structures.
