Estudio geotécnico in El Hoyo de Pinares

In El Hoyo de Pinares, the subsoil is dominated by the presence of granite, gneiss and other igneous rocks, which represents a compact ground with high bearing capacity. These rock formations, which are widely impermeable or have very low permeability, are favourable for direct foundations using strip footings or a slab, although special excavation techniques may be necessary due to the hardness of the subsoil. The abundance of shallow aquifers is associated only with formations locally altered, which habitually do not affect the overall ground stability for civil works.

Seismic activity in the municipality is classified as moderate, with 32 recorded events in the last three decades and a maximum magnitude of Mmax 2.8, which does not entail any relevant impact on the structural design. The absence of clayey soils eliminates the risk of expansivity, thereby ruling out problems due to ground volumetric heave. The main conditioning factor for geotechnical study in El Hoyo de Pinares is the precise identification of the depth of fresh rock and its degree of alteration—key aspects for designing safe and optimised foundations.
