Estudio geotécnico in Capela, A

In the municipality of Capela, A, the soils are predominantly composed of sandstones, conglomerates and flysch, representing more than 98% of the substrate. These lithologies are characterised by high consistency and good bearing capacity, which facilitates the design of shallow foundations without major technical complications. However, the low permeability of these materials often leads to the presence of shallow aquifers located mainly in areas where the relief favours the accumulation of water, which may require special attention during the excavation phase and the monitoring of the groundwater table.

With regard to the seismicity of Capela, A, 20 events have been recorded over the last 30 years, with a maximum magnitude of 1.8, indicating moderate seismic activity and no significant implications for the usual structural design. The geotechnical study does not reflect the presence of karstic processes or risks associated with expansivity, since the non-clayey nature of the substrate rules out this type of instability. The main factor to consider in geotechnical studies of the area is the possible presence of locally aquiferous levels and the appropriate control of drainage in foundation works.
