Estudio geotécnico in Láncara

In Láncara, the predominant subsoil is made up of slates and schists, which provides ground essentially with low to medium bearing capacity and a tendency towards compressible behaviour limited in extent. Granite and igneous rocks, present in significant amounts, provide localised areas with greater strength and stability for shallow foundation. Fine loose materials, such as sands and silts, occur only occasionally and very rarely influence significantly, although they require a site-specific assessment where they are present. In general, low permeability predominates, restricting the movement of water at depth and limiting the presence of aquifers, which influences the long-term behaviour of foundations.

The area shows notable seismicity, with 148 events over 30 years and a maximum magnitude (Mmax) of 5, a circumstance that necessitates considering seismic actions in the structural design. The possible presence of karst increases the need for prior studies of cavities and ground dissolution before carrying out any foundation works, in order to avoid risks associated with the phenomenon. As the subsoil is non-clayey, the risk of expansivity is ruled out, so the main condition for any geotechnical study in Láncara will be investigation of seismicity and verification of the potential for karstification; these are indispensable aspects for ensuring the future stability of the structures.
