Estudio geotécnico in Calzada de Calatrava

In Calzada de Calatrava, soils of slate and schist predominate, accounting for most of the substrate. These formations are typically characterised by high consistency and very low permeability, which has a favourable effect on the ground’s bearing capacity and provides ideal conditions for direct foundations, both shallow and semi-deep. The occasional presence of hard clays and marls very rarely compromises stability; however, it is recommended to verify the homogeneity of the supporting layers and their compactness before carrying out foundation works.

Seismicity in the area is very low, with only 2 recorded events over 30 years and a low maximum magnitude, so it does not constitute a relevant constraint for structural design. The non-clayey substrate rules out the risk of ground expansivity. The main factor to consider in any geotechnical study in this municipality is to check the compactness and continuity of the slate and schist package, due to its direct influence on the stability and behaviour of the foundation.
