Estudio geotécnico in Garrafe de Torío

In Garrafe de Torío, soils formed by sandstones, conglomerates and flysch predominate, accounting for the vast majority of the substrate and providing favourable characteristics for foundations, thanks to their good bearing capacity. The presence of fine sands, silts and compact gravels, although in smaller proportions, complements the lithological mosaic, while the existence of extensive aquifers with high permeability requires an adequate hydrological assessment for the design of foundations and to prevent possible differential settlements in areas locally saturated.

Seismic activity in the municipality is considered moderate, with 11 events in the last 30 years and a maximum magnitude of 2.7, meaning that seismic risk on structural design is low. The risk of expansivity arising from the presence of expansive clays is secondary and mainly associated with very localised zones or special climatic conditions, so it does not constitute a general constraint within the municipal term. The heterogeneity of the subsoil and the management of the presence of groundwater will be the main factors to analyse in any geotechnical study in Garrafe de Torío.
