Geotechnical study in Pozuelo del Rey

In Pozuelo del Rey, the ground is composed mostly of limestones, dolomites and marbles, with a significant presence of sandstones, conglomerates and flysch, while white or soft expansive clays occupy only a very small percentage of the surface. The predominance of carbonate and siliciclastic rocks generally provides a good bearing capacity for shallow foundations, although local variability may require specific studies to optimise the foundation design and ensure its safety in the presence of aquifers with moderate permeability.

Seismicity in the municipality is very low, with just 1 event in 30 years and a maximum magnitude of 1.6, which reduces the seismic design requirements. However, since it is located in a non-clayey substrate context, the risk from expansivity is ruled out. It is important to note that, due to the karstic nature of the predominant carbonate formations, it is essential to verify the existence of cavities or dissolution phenomena before proceeding with the foundation, and this aspect is the main geotechnical constraint in the area.
