Estudio geotécnico in Santa Lucía de Tirajana

In Santa Lucía de Tirajana, the predominant subsoil is made up of granite, gneiss and other igneous rocks, combined with significant outcrops of sandstones and conglomerates. This type of ground provides a high bearing capacity and, in general, allows the use of robust shallow foundations. Fine sands, silts and some layers of overconsolidated clays occur occasionally, so it is always advisable to assess the continuity and depth of the competent stratum before defining the foundation system, ensuring proper adaptation to local heterogeneity.

Historical seismic activity is very low, with only 6 events in the last 30 years and a maximum recorded magnitude (Mmax) of 3.3, which minimises seismic design requirements at structural level. There are no records of karstification or signs of soils with significant expansivity, so the main geotechnical constraint in the area will be the correct identification of the dominant lithology and the local variability of less competent strata, which may require specific project-level solutions.
