Estudio geotécnico in Guijo de Galisteo

In Guijo de Galisteo, the dominant substrate is formed by phyllites and schists, present in 77.8% of the municipality, accompanied by smaller areas of sandstones, conglomerates and flysch, as well as small outcrops of granite and gneiss. These lithologies, mostly of low permeability, provide stable conditions for shallow foundations, although they may require specific monitoring of superficial aquifers in isolated cases of interstitial water. The bearing capacity is usually sufficient for residential and agricultural buildings, with no presence of soft soils such as muds or peats, which makes it easier to select the type of foundation in this geological setting.

Seismic activity in Guijo de Galisteo is notable, with 56 events recorded over the last 30 years, although with a maximum magnitude of 3.1, which implies a low structural hazard associated with earthquakes. There is no risk from karstification or expansivity, since the substrate is not clayey, ruling out volumetric problems stemming from moisture changes. The most important factor to consider in a geotechnical study for this municipality is the impermeable and compact nature of the phyllites and schists, which governs both drainage capacity and the foundation design.
