Estudio geotécnico in El Gastor

In El Gastor, the dominant subsoil consists of compacted gravels and sands, present throughout the entire study area. Owing to their density and coarse grain size distribution, these soils offer good conditions for bearing capacity, enabling the execution of shallow (direct) foundations with optimal results and reduced deformability. The permeability associated with this type of material also facilitates natural drainage, decreasing the likelihood of problems caused by capillary rise or moisture retention beneath the footings.

From the seismic standpoint, El Gastor shows very low activity, with only 3 events in the last 30 years and a maximum magnitude of 2.9—values that do not require special considerations in structural design. The fact that the subsoil is not clayey removes any concern regarding expansiveness. Thus, the main constraint for the geotechnical study in the locality is the appropriate characterisation of the density and uniformity of the gravel and sand deposit.
