Estudio geotécnico in Ramirás

In the municipality of Ramirás, the prevailing geological substrate is made up of sandstone, conglomerate and flysch formations, together accounting for more than 75% of the surface area, which suggests soils with mechanical characteristics that are generally favourable for foundations, although possible localised variations must be taken into account. Occasional materials, such as slates and schists, and sporadic outcrops of granite and gneiss reinforce the presence of competent soils. The low permeability of these formations means they may be able to store shallow aquifers in specific areas, but they normally provide good bearing behaviour, facilitating the design of shallow or semi-deep foundations depending on the anticipated structural loading.

Seismic activity in Ramirás is moderate, with 24 recorded events over the last 30 years and a maximum magnitude (Mmax) of 3.2, so it does not represent a critical constraint in the preparation of the structural design or in the foundation stage. In addition, the substrate composition is free of expansive clays, which virtually rules out the risk of swelling and shrinkage, eliminating one of the main geotechnical concerns in the area. No karst processes are detected, so the main condition to be checked focuses on the homogeneity of the bearing substrate and the possible presence of lenses of less competent materials within the sedimentary formations.
