Estudio geotécnico in La Zarza

In La Zarza, the dominant substrate is made up mainly of slates and schists, which favours the presence of low-permeability soils. This type of material provides a moderate bearing capacity, and is suitable for shallow foundations provided that the possible presence of altered near-surface layers or aquifers is controlled. The predominant formations hinder infiltration, so it is essential to carry out a detailed analysis of the water table level before deciding on the foundation type, especially in large-scale projects.

Seismicity in this municipality is very low, with only 1 event in 30 years and a maximum magnitude of 1.5, so it is not considered a relevant constraint for structural design. Since the substrate is not clayey, the risk of expansivity is ruled out, minimising complications associated with volumetric movements. The main factor that must be verified is the influence of the water table level on the bearing capacity of the slates and schists, as this is the most relevant aspect in the planning of new foundations in the area.
