Estudio geotécnico in Lubrín

In Lubrín, schists and shales predominate as the substrate, accounting for more than two thirds of the ground, accompanied by fine sands and silts in smaller proportions, as well as localised deposits of gypsum, anhydrite and salts. These lithologies often combine low permeability with bearing capacities that are generally sufficient for normal building, although sand and silt formations may require specific analysis to prevent excessive settlement. The occasional presence of gypsum, anhydrite and salts implies a risk of dissolution, so extreme precautions must be taken both in prior studies and during the execution of the foundations.

Seismic activity in Lubrín is moderate, with 27 events in the last 30 years and a maximum magnitude of 4, which makes it prudent to consider seismic action in the structural design calculations. As it is an area where karst development occurs, it is essential to check for the possible presence of cavities or dissolution before determining the most suitable foundation type. Since the substrate is not clayey, there are no problems related to expansivity, but the main limiting factor for the geotechnical study lies in monitoring risks arising from karstification and the presence of soluble materials.
