Estudio geotécnico in Barruelo de Santullán

In Barruelo de Santullán, the dominant geological substrate is composed primarily of sandstones, conglomerates and flysch, occasionally accompanied by fine sands, silts, limestones, dolomites and marbles. This type of material usually provides good bearing-capacity conditions for foundations, although the spot presence of gypsum, anhydrite and salts may entail dissolution risks, which means that a specific analysis is essential in these areas. In addition, the generally low permeability of the formations can affect the discharge of water, which should be considered in foundation design projects.

The area shows notable seismicity, with 57 events in the last 30 years and a maximum magnitude of 4, implying the need to maintain adequate structural design against seismic actions, although without reaching critical values. The surroundings are potentially karstifiable, so the presence of cavities or discontinuities must be verified before constructing, especially in the limestone and dolomite areas. The non-clayey substrate minimises any expansivity risk, although the main constraint will be assessing karst-related phenomena and the possible dissolution of saline materials in order to guarantee the safety and stability of future developments.
