Estudio geotécnico in Arona

In Arona, the predominant substrate consists of sandstones, conglomerates and flysch, which account for the greatest proportion of the soils in the area. This type of material typically provides a moderate bearing capacity, although the lithological variability may require a detailed analysis in order to define optimal foundation solutions. Granite and other igneous rocks appear occasionally, providing exceptionally resistant support where they are located. The minor presence of white expansive clays, although rare, makes it necessary to identify them precisely in order to rule out localised issues affecting the stability of the foundations.

From a seismic standpoint, Arona has moderate seismicity, with 11 recorded events over 30 years and a low maximum magnitude (Mmax 2.1), so in practice the impact on structural design is limited. No karst development is identified, meaning there is no associated risk of sinkholes or subsidence. The risk of expansivity is low, except in very specific areas where small pockets of white expansive clays may occur. Thus, the main factor to take into account for the geotechnical study in Arona is lithological heterogeneity, making it essential to identify the competent strata that allow safe and homogeneous foundations.
