Estudio geotécnico in San Miguel de Salinas

In San Miguel de Salinas, fine sands and silts predominate, representing close to 62% of the substrate, accompanied by a significant proportion of limestones, dolomites and marbles. This geotechnical context implies varying bearing capacities, with higher values in the carbonate areas where conventional foundations are feasible, and some caution in fine granular ground or over poorly consolidated sediments. It is important to carry out a detailed investigation to determine the optimum support level and to avoid foundation works on unstable zones or near masses of water.

Seismicity in the municipality is moderate, with 11 recorded events over the last 30 years and a maximum magnitude of 3.3, which necessitates a review in the structural design in accordance with current regulations. The presence of carbonate formations implies the possibility of karst phenomena developing, so the existence of cavities must be verified specifically before proceeding with the foundation. As the substrate is non-clayey, there is no relevant risk from expansivity; the main constraint is potential karst activity in the subsurface.
