Geotechnical study in Òdena

In Òdena, formations of sandstone, conglomerates and flysch predominate, accounting for approximately 69% of the soils, and are characterised by their low permeability, although aquifers may occur at greater depths. These materials generally show good bearing capacity for shallow foundations, especially in relation to the areas of white and soft expansive clays, which, although they occupy a smaller proportion, must be identified and treated appropriately before the foundations are constructed.

Seismic activity in Òdena is very low, with barely two events in the last thirty years and a maximum magnitude of 2.3, so it does not constitute a relevant constraint for structural design. Nevertheless, in the area there is a possibility of karst presence, making it essential to verify this geological phenomenon prior to the construction process, as it can affect ground stability. The non-clayey substrate rules out the risk of expansivity, so the main aspect to consider in the geotechnical study of Òdena will be the identification of possible karst cavities.
