Estudio geotécnico in Touro

In Touro, slates and schists predominate, representing 65,47% of the soils, alongside a significant presence of sandstones, conglomerates and flysch. These formations usually have moderate bearing capacity, favouring direct foundation solutions in most projects. Fine sand and silt layers are rare, so the conditions of firmness for supporting foundations are generally suitable, although stability and compaction should be checked given the laminated nature of the slates and schists.

The municipality’s seismicity is moderate, with 21 events recorded in the last 30 years and a maximum magnitude (Mmax) of 2, so the seismic influence on design is low. The analysis reveals the absence of risk from expansive soils due to the non-clayey substrate, and no karst processes are identified. The main geotechnical consideration lies in the heterogeneity and low permeability of the materials, which may influence the ground’s drainage behaviour.
