Estudio geotécnico in Alfarnate

In the municipality of Alfarnate, calcareous materials predominate, such as limestones, dolomites and marbles, which provides a consistent geological base across more than 75% of the territory. These stony soils offer a high bearing capacity and usually allow shallow or semi-deep foundations, with the exception of isolated areas covered by sandstones or flysch. Permeability is variable: formations of low permeability predominate, although there are sectors where small aquifers may develop.

With regard to geotechnical risks, the presence of a karstic setting is significant: before planning the foundation, it is essential to check for possible cavities or underground dissolution processes associated with the limestone, as these may affect stability. Alfarnate’s seismicity is moderate (48 events over 30 years, maximum magnitude of 3.1), requiring assessment but without being the main determining factor. The subsoil is not clayey, ruling out any risk of expansivity. The determining factor for any geotechnical study in Alfarnate will be the prior verification of risks associated with karst in the vicinity of the foundation.
