Estudio geotécnico in Vícar

In the municipality of Vícar, the dominant geological substrate is mainly composed of limestones, dolomites and marbles, representing close to 63% of the ground. These materials, of competent nature and high bearing capacity, favour the viability of shallow foundations. However, soils of gypsum, anhydrite and salts are also observed, which may present a risk of dissolution, as well as the occasional presence of sands and silts that require a specific analysis of their compactness to avoid differential settlement. On the other hand, the existing non-clayey substrate eliminates concern about soil expansivity problems.

Seismic activity in Vícar is moderate, with 26 recorded events over the last 30 years and a maximum magnitude (Mmax) of 3.6, which implies standard monitoring, without any specific requirements for seismoresistant structural design. However, the possible presence of karst in the carbonate formations makes it essential to verify in detail the existence of cavities before carrying out any foundation, since these discontinuities can jeopardise the stability of the infrastructure. Thus, the primary technical constraint for the geotechnical study in Vícar lies in assessing karst risk and the interaction with soluble soils.
