Geotechnical study in Aragon

The province of Zaragoza, located in the eastern region of Aragon, displays a variety of ground conditions that influence geotechnical studies. Franco-sandy and silty soils predominate in areas close to the River Ebro, with recent alluvial deposits that require specific analysis for foundations. In contrast, the areas of the Bajo Aragón region concentrate clayey and calcareous soils, which exhibit high susceptibility to swelling and differential shrinkage, affecting the stability of structures. In the central depression, formations of sedimentary rocks and marls provide conditions with varied texture and permeability, which in turn affects mechanical properties and drainage. The land distribution in mountainous zones, such as the Sierra de Guara, is characterised by shallow, rocky soils with steep gradients, which limit certain types of development and require specific studies to identify potential landslide risk. These geotechnical characteristics, depending on the distribution of soil types, are essential for assessing stability and the feasibility of projects in different Aragonese comarcas.
