Estudio geotécnico in Barreiros

In the municipality of Barreiros, slates and schists predominate by a wide margin, which results in a subsoil with high strength and low deformability. These materials generally have an adequate bearing capacity for most conventional foundation solutions, although their low permeability can influence the hydraulic behaviour of the ground and the management of shallow groundwater. It is essential to assess the possible presence of shallow aquifers in areas where infiltration is concentrated.

Seismicity in Barreiros is moderate, with 10 events over the last 30 years and a maximum recorded magnitude of 3.2, so the seismic risk is low in foundation projects. However, since there is karst potential in the area, a rigorous check for the presence of karst is recommended before carrying out any foundation, as cavities or voids that are not detected may compromise structural stability. In this context, the main conditioning factor for the geotechnical study is the possibility of karst development in the bedrock.
