Estudio geotécnico in Lecrín

In Lecrín, soils of slates and schists predominate, covering most of the municipality, whereas limestones, dolomites and marbles occur only occasionally. These lithologies give the ground low permeability, although they may give rise to shallow aquifers in specific areas. Bearing capacity is usually high over slate or schist bedrock, providing good conditions for shallow foundations, provided that foundations are not laid on altered materials or in transition zones to limestone areas, where cavities could occur.

Seismic activity in Lecrín is very low, with no records of events of significance and a low maximum magnitude, which minimises this factor in structural design. However, the presence of carbonate materials implies the potential development of karst; therefore, it is essential to verify the existence of cavities or dissolution processes before carrying out any foundations, as this phenomenon is the main local conditioning factor. The absence of clays and a non-clayey substrate exclude the risk of expansivity for constructions in the area.
