Estudio geotécnico in Baleira

In Baleira, the geological substrate is dominated by the presence of slates and schists, which make up more than 90% of the ground and have very low permeability. These materials, being mostly hard and compact, generally provide good conditions for bearing capacity, although local fracturing may influence the choice of the appropriate foundation type. The occasional presence of fine sands and silts is minimal and, in general terms, the risk associated with their behaviour is low for most construction projects, although their specific identification is recommended during the geotechnical study.

Seismicity in the area is moderate, with 15 events recorded over 30 years and a maximum magnitude of 3.2, which implies a moderate requirement in the structural analysis from the seismic viewpoint. However, Baleira is located in an area where conditions are favourable for karst processes, so before carrying out any foundation work, it is essential to verify the presence of cavities or dissolutions that could affect ground stability. Since the substrate does not contain expansive clays, the risk of expansivity can be ruled out as a relevant limiting factor, the main geotechnical challenge being the possible presence of karst.
