Estudio geotécnico in Laujar de Andarax

In Laujar de Andarax, slates and schists predominate, accompanied in smaller proportions by limestones, dolomites and marbles. These soil types generally exhibit low permeability and, although they may host some shallow aquifers, their bearing capacity is variable. Slates and schists provide adequate strength for shallow foundations provided they are found in a compact state, whereas limestones and dolomites generally allow direct foundations but require point-by-point analysis of associated discontinuities and voids.

The seismic activity recorded in the area is very low, with 5 events over the last 30 years and a maximum magnitude of M4, so seismicity does not represent an important structural constraint. However, the presence of limestones and dolomites requires verifying the development of karst processes before defining the foundation solution, as cavities or voids may exist that could compromise stability. The risk of expansivity is ruled out because the substrate is non-clayey; thus, the main geotechnical constraint in Laujar de Andarax is the possible occurrence of karstification in the carbonate levels.
