Estudio geotécnico in Viveiro

In Viveiro, the geological substrate is dominated by slates and schists, followed by sandstones and conglomerates, which ensures a relatively compact and strong rock base. These lithologies generally exhibit low permeability and provide adequate bearing capacity for conventional buildings, allowing shallow-type foundations in most cases, except in very localised areas where there may be alterations or residual materials.

Seismicity in the municipality is very low, with only 8 events over 30 years and a maximum magnitude of 2, which does not create special requirements for structural design. As the substrate is non-clayey, there is no significant risk of ground expansiveness. No karstification phenomena have been recorded, so the most relevant constraints for the geotechnical study focus on the local characterisation of the altered rock and the identification of potential superficial aquifers in isolated levels.
