Estudio geotécnico in Taboada

In Taboada, the geological substrate is defined fundamentally by the presence of sandstones, conglomerates and flysch, followed by slates and schists. These materials, of predominantly rock nature and variable strength, provide a generally favourable bearing capacity for shallow and semi-deep foundations, although the low permeability of these lithologies may give rise to localised superficial aquifers that it is advisable to take into account in drainage or waterproofing planning. The limited presence of water bodies implies specific risks mainly associated with temporary saturation in areas nearby.

The seismicity in the municipality is classified as notable, with 88 events in the last three decades and a maximum recorded magnitude of 4, which indicates the need to apply specific seismic criteria in the structural design of new buildings. No karst formations are detected and there is no risk from expansive soils, since the substrate is not clayey. The most relevant constraint for geotechnical projects in Taboada is the combination of notable seismicity and the heterogeneity in the strength and permeability of the materials present.
