Estudio geotécnico in La Puerta de Segura

In La Puerta de Segura, the dominant substrate is made up of slates and schists, determining geotechnical conditions of low permeability. These materials, of metamorphic nature, generally offer good bearing capacity, which facilitates the execution of conventional shallow foundations, although it is essential to assess the presence of possible levels of alteration or surface weathering that may reduce the homogeneity of the ground support.

Seismic activity in the area is high, with approximately 200 events recorded over the last 30 years, although the maximum magnitude does not exceed 4.4, so construction projects must take account of seismic loads appropriate to the conditions. There is no development of karst and, since the substrate does not present clayey materials, the risk of expansivity can be ruled out. The main factor conditioning foundations in La Puerta de Segura is the correct characterisation of the degree of weathering of slates and schists, together with the mandatory consideration of the seismic context in the structural design.
