Estudio geotécnico in Villagonzalo Pedernales

In Villagonzalo Pedernales, soils formed by limestones, dolomites and marbles predominate, accompanied by significant percentages of gypsum, anhydrite and salts, as well as sandstones and conglomerates. These lithologies habitually exhibit good bearing capacity for shallow foundations, although the presence of gypsum and anhydrite implies a high risk of dissolution processes; therefore, a detailed analysis is recommended before determining the optimal foundation solution. Compact gravels and sands are considered infrequent and, although they offer good geotechnical conditions, they have little impact on the general context of the municipality.

Seismicity in Villagonzalo Pedernales is very low, with only 4 recorded events over 30 years and a maximum magnitude of 1.7, which minimises the need for seismic requirements in structural design. The absence of clayey strata eliminates the risk of expansivity, thereby ruling out problems associated with expansive movements. The main geotechnical constraint in this municipality is therefore the potential risk of dissolution linked to the significant presence of gypsum, anhydrite and salts in the ground.
