Estudio geotécnico in Santa Pau

In Santa Pau, the geological substrate is dominated by two major lithological groups: sandstones, conglomerates and flysch, as well as granite, gneiss and other igneous materials. Both types of formations exhibit characteristics of high compactness and strength, which positively affects the ground bearing capacity and makes it possible to use conventional shallow foundations. However, the generally low permeability implies the possible presence of localised near-surface aquifers, which requires checking stability and drainage when designing foundations.

Seismic activity in Santa Pau is very low, with only a single event recorded in 30 years and a maximum magnitude of 2, which eliminates seismicity as a relevant design constraint in local engineering. In addition, the non-clayey composition of the substrate rules out risks associated with expansive soils. The main point to consider in the geotechnical studies for this municipality will be the detailed assessment of lithological heterogeneity and hydrogeological behaviour in areas with shallow aquifers.
