Estudio geotécnico in Ezcaray

In Ezcaray, slates and schists predominate, with a 77,38% incidence, followed in smaller proportions by sandstones, conglomerates and flysch. These materials offer low permeability at the surface, which implies generally favourable bearing capacities, although it may be necessary to investigate the continuity and stability of the strata, particularly for shallow or deep foundations. The possible presence of aquifers at greater depth should be considered in the design phase in order to avoid undesirable interferences during excavation or foundation works.

Seismicity in Ezcaray is very low, with only 4 events detected over 30 years and a recorded maximum magnitude of 1.8, which allows this factor to be ruled out as a relevant structural constraint. The non-clayey substrate eliminates the risk of expansivity, but as it is located in an area where the karst phenomenon may be present, it is essential to verify the existence of cavities or dissolution before proceeding with the foundations to prevent differential settlement or instability.
