Estudio geotécnico in Incio, O

In the municipality of O Incio, substrates made up mainly of slates and schists predominate by a large margin, accounting for more than 90% of the surface area, accompanied to a lesser extent by gravels and compact sands. This type of ground, generally of low permeability, offers an adequate bearing capacity for conventional deep or shallow foundations, although it may host small local shallow aquifers. Direct support on slates and schists is favourable, whereas the gravels and compact sands, although uncommon, also provide good conditions for construction.

From the point of view of geotechnical risk, seismicity in O Incio is high, with around 200 events recorded over the last 30 years and a maximum magnitude reaching 5, so this aspect must be considered obligatorily in the design of structures and infrastructure. There is no risk of expansivity associated with clayey soils, given the lithological character of the substrate, nor have any karst phenomena been identified in the municipality; in this context, seismicity is the critical factor to be controlled in geotechnical studies prior to any work.
