Estudio geotécnico in Fuente de Pedro Naharro

In Fuente de Pedro Naharro, the ground is composed mainly of sandstones, conglomerates and flysch; these elements give the subsoil a favourable bearing capacity for building projects, especially when the support levels are located on compact formations. The occasional presence of limestones, dolomites and marbles introduces the factor of carbonate rocks, while the significant proportion of gypsum, anhydrite and salts implies a risk of dissolution, which can lead to instabilities if it is not correctly identified during the geotechnical study. Given the low permeability of most materials, deep aquifers are usually found, which is a relevant aspect for foundation safety.

Seismicity in the municipality is very low, with only 1 event in 30 years and a maximum magnitude of 2.2; therefore, this parameter does not condition the criteria for structural design in the area. However, the potential development of karst processes in the limestones, dolomites and marbles requires specific verification of the existence of cavities or voids before any foundation is executed, since they may represent a fundamental constraint on the feasibility and safety of the structure. The risk of expansivity is negligible, as the substrate is not formed by expansive clays; accordingly, attention should focus on the possible presence of karst and the dissolution of evaporitic materials as the main conditioning factor of the geotechnical study.
