Estudio geotécnico in Vélez-Rubio

In Vélez-Rubio, the dominant substrate is composed of phyllites and schists, present at 59.58%, accompanied by secondary deposits of fine sands and silts at 29.08%. These formations show low permeability, although they may contain localised shallow aquifers. The presence of phyllites and schists gives the ground a moderate bearing capacity, which generally allows for shallow direct foundations, although attention must be paid to ground heterogeneity due to areas of looser materials such as sands and silts.

The area has moderate seismicity, with 22 events recorded in the last 30 years, with a maximum magnitude of 3.5, which, although it does not represent a first-order constraint, should be considered in sensitive projects. In addition, given the risk of karstification, it is essential to check in advance for cavities or dissolution in the subsoil before any foundation works. The non-clayey substrate rules out the possible presence of problems linked to expansiveness. The most relevant factor for the viability and safety of foundations in Vélez-Rubio is prior verification of karst, in combination with care regarding low compaction materials.
