Geotechnical study in Pazos de Borbén

In Pazos de Borbén, the soils formed by sandstones, conglomerates and flysch predominate, accompanied to a lesser extent by shales and schists. This substrate generally exhibits low permeability, limiting the development of deep aquifers and affecting the drainage of the ground. For the calculation of bearing capacity and the selection of the foundation, it is important to consider the competent nature of these materials, which usually provide a good response as direct support, although they may require a detailed study of discontinuities and surface alterations.

Seismic activity for the municipality is moderate, with 14 events recorded in the last 30 years, with a maximum magnitude of M4, which calls for minimal attention in structural design, although it does not severely condition projects. The non-clayey substrate removes concern about expansiveness, and there are no risks associated with karst development. Thus, the main starting consideration centres on the homogeneity and mechanical alteration of the dominant rocks.
