Estudio geotécnico in Puigcerdà

In Puigcerdà, a substrate composed mainly of slates and schists predominates. These materials provide a generally competent and stable foundation base, although with low permeability. The presence of fine sands and silts, as well as sections of sandstone and conglomerates, introduces some variation in bearing capacity, which requires attention when determining the most suitable foundation depth and type. Gravel and compact sand soils, although less frequent, can offer good conditions as a support level, provided that continuity and homogeneity of these layers are verified.

Seismicity in Puigcerdà is very low, with only 7 recorded events over 30 years and a maximum magnitude of 3; therefore, seismic risk is not considered a relevant conditioning factor in local geotechnical design. No karst phenomena or risk of expansiveness are observed in the substrate, since it is not clayey. For all these reasons, the main factor to consider in geotechnical studies in the area is the lithological variability that can influence bearing capacity and the appropriate selection of the foundation.
