Estudio geotécnico in Dosrius

In Dosrius, the predominant subsoil is formed by granite, gneiss and other igneous rocks, representing approximately 87.5% of the ground. These materials offer a high bearing capacity, a favourable feature for most shallow or semi-deep foundations, depending on the presence of altered zones. Fine sands and silts, present in a smaller proportion, may require caution due to their lower strength and higher compressibility, although their low frequency reduces their impact on the overall choice of foundation type.

Seismic activity in the municipality is very low, with only 1 event in the last 30 years and a maximum magnitude that does not exceed 1.5; therefore, this factor is of no relevance for structural design purposes. Since the subsoil is not clayey, any risk of expansivity is ruled out. Thus, the main technical consideration for the geotechnical study of Dosrius lies in characterising the degree of alteration of the igneous rocks and in the point-by-point detection of any soft granular soils that might require specific solutions.
