Estudio geotécnico in Fresnedillas de la Oliva

In Fresnedillas de la Oliva, the dominant substratum is made up of granitites, gneisses and other igneous rocks, accompanied in smaller proportions by slates and schists. These materials give the ground high competence and good bearing capacity, which facilitates the selection of shallow and direct foundations in most cases. The very low permeability reduces the risk of liquefaction or differential settlements caused by water, although shallow aquifers may be found in altered zones, which requires a specific review during any geotechnical study.

Seismic activity in the municipality is residual, with a very low frequency of events and a very low maximum magnitude, which minimises the need to consider seismic risk in structural design. The nature of the substratum, clearly non-clayey, eliminates any concern related to soil expansivity. In the absence of karst and of chemically unstable materials, the main condition in Fresnedillas de la Oliva lies in characterising the near-surface alteration of the rock mass.
