Geotechnical study in Burguillos de Toledo

In Burguillos de Toledo, the subsurface is mainly made up of slates, schists and a significant percentage of granite, gneiss and other igneous rocks. These lithologies ensure good bearing capacities for building works, allowing shallow foundations in most cases, although the occasional presence of overconsolidated clays and marls may require a local assessment to avoid differential settlement problems. The predominant formations generally show low permeability, which limits water infiltration and promotes long-term stability.

Seismicity in the Burguillos de Toledo area is high, with approximately 200 events over 30 years and a recorded maximum value (Mmax) of 5.1. This level of seismic activity implies that seismic design criteria must be considered in structural projects. There are no signs of karstification or risks of expansivity, since the substrate is not clayey, which reduces concern regarding volumetric ground movements. The main geotechnical constraint for this municipality is therefore seismic action, which must be integrated into the analysis and design of the foundations.
