Estudio geotécnico in Pobla del Duc, la

In La Pobla del Duc, soils formed by limestones, dolomites and marbles predominate; these materials have high mechanical competence and provide excellent bearing capacity for the foundations of buildings and infrastructure. Although small proportions of fine sands and silts are observed, as well as areas with waterlogged mass, the dominant soils do not present any relevant difficulties for shallow foundation, except locally where alluvial deposits may reduce ground homogeneity or induce slight variations in permeability.

With regard to seismicity, the area has recorded moderate activity with 27 events in the last 30 years and a maximum magnitude of less than 4.5, which implies that specific earthquake structural design is not required in most cases. The underlying stratum is not clayey, which de facto rules out any risk associated with expansive soils. In conclusion, the main geotechnical constraint in La Pobla del Duc is the predominance of competent rock materials, which allow conventional foundations to be considered with few specific restrictions.
