Estudio geotécnico in Torrejoncillo

In Torrejoncillo, soils formed by phyllites and schists predominate, representing more than 60% of the substrate, accompanied in smaller proportions by sandstones, conglomerates and flysch formations. These lithologies generally show adequate bearing capacity for conventional shallow foundations, although the possible presence of fracturing in areas of phyllites should be considered, as this could affect the uniformity of the support. Permeability is low in most cases, although locally small superficial aquifers may develop; therefore, it is essential to analyse the groundwater level before carrying out deep foundations.

Seismic activity in Torrejoncillo is classified as notable, with 56 recorded events over 30 years, although the maximum magnitude (Mmax 3.1) remains within low values, which minimises the seismic requirements for structural design. The non-clayey substrate eliminates the concern regarding expansivity in the ground, allowing greater flexibility in selecting the type of foundation. The main constraint for geotechnical studies in this municipality is usually linked to the degree of alteration of the phyllites and possible variations in the groundwater level.
