Estudio geotécnico in Muel

In Muel, materials of high compactness predominate, such as limestones, dolomites and marbles, which translates into good bearing behaviour for most foundation design projects. The secondary presence of sandstones, conglomerates and flysch also provides resistance to shear, while the occasional occurrence of gypsum, anhydrite and salts introduces some caution regarding risks of dissolution. The extensive network of aquifers and the very high ground permeability require appropriate groundwater management in design, but in general the solid substrate is favourable for spread footings or deep foundations, depending on loads and geometry.

Seismic hazard in Muel is considered moderate, with 17 events over the last 30 years and a relatively low maximum magnitude (Mmax 2.5), so the impact on structural design is limited. Nevertheless, a thorough check must be carried out on the existence of karstic phenomena, especially in areas of limestone and gypsum, before defining the foundation, since karst activity can affect the stability and uniformity of the support. As it is a non-clayey substrate, the risk of expansivity is ruled out, establishing as the main determining factor the possible presence of karst cavities and dissolution processes, aspects that the geotechnical study must address in detail.
