Estudio geotécnico in Vedra

In the municipality of Vedra, slates and schists predominate, followed by sandstones, conglomerates and flysch. These materials are characterised by low to very low permeability, which significantly restricts the presence of deep aquifers, although poorly developed aquifers may exist in shallow levels. The bearing capacity of these soils is usually suitable for most buildings, enabling the execution of shallow or semi-deep foundations depending on the degree of weathering and fracturing of the rock.

As for seismicity, Vedra shows a moderate level with 40 events over 30 years and a maximum magnitude (Mmax) of 3.1, which implies a low seismic risk in the structural context. No karst-related phenomena are associated with these materials, and the non-clayey substrate rules out risks due to soil expansivity. The main geotechnical constraint in the area derives from the characterisation and continuity of the rock materials, and a detailed investigation is recommended to avoid zones that are deeply weathered or fractured.
