Estudio geotécnico in Fresno de Torote

In Fresno de Torote, the dominant substrate is composed mainly of sandstones, conglomerates and flysch, which account for about two thirds of the surface composition. These materials usually exhibit good bearing capacity, allowing shallow foundations in most cases, particularly in areas of extensive aquifers and very permeable soils such as those found in this municipality. Limestones, dolomites and marbles occur only in specific places, providing areas with higher resistance, whereas shales and schists, although less common, may cause variability in the local mechanical behaviour of the ground.

Seismicity in Fresno de Torote is very low, with only 5 recorded events over 30 years and a maximum magnitude (Mmax) of 3, so it does not constitute a relevant conditioning factor in structural design. Expansive clays are only present in a subordinate way or in areas with low climatic influence, significantly limiting the risk of volume-change movements due to expansivity. The main point to assess is the correct characterisation of the materials present and consideration of the possible discontinuity that the aquifers may create in the foundation area.
