Estudio geotécnico in Magaz de Pisuerga

In Magaz de Pisuerga, the predominant ground consists of limestones, dolomites and marbles, providing a substrate with high bearing capacity and suitable for the foundation of conventional structures. In addition, in smaller proportions there are compact gravels and sands, which are also favourable from a geotechnical perspective. However, the presence of strata with gypsum, anhydrite and salts indicates the risk of dissolution, which may affect differential settlements. Permeability is high due to extensive and productive aquifers, an aspect that is relevant in retaining works or deep excavations.

Seismic activity in the area is notable, with 57 recorded events over the last 30 years, although with a moderate maximum magnitude (Mmax 4). The presence of karst formations requires detailed verification before any foundation project, as underground voids may exist. The absence of clayey strata rules out expansivity risks. In conclusion, the most relevant controlling factor for the geotechnical study in Magaz de Pisuerga is the presence of karst processes and dissolution, which must be examined thoroughly to avoid pathologies associated with ground instability.
