Estudio geotécnico in Galaroza

In Galaroza, substrates of phyllites and schists predominate, followed by granite and gneiss, which creates foundation conditions on hard, scarcely deformable materials. These soils generally show low permeability and may occasionally contain shallow aquifers; however, their bearing capacity is usually favourable for most buildings, provided that the stratigraphic profile is properly characterised to identify any possible fractures or altered layers.

Seismic hazard in the area is very low, with only 4 events recorded over 30 years and a maximum magnitude of 2.1, so it does not constitute a relevant design constraint. Although the substratum is not clayey and rules out the risk of expansivity, the possibility of developing karstic phenomena must be checked thoroughly before designing any foundation; this is the main factor requiring geotechnical caution in the municipality.
