Estudio geotécnico in Fasnia

In Fasnia, sandstone, conglomerates and flysch predominate, followed by granite, gneiss and other igneous rocks. These materials generally exhibit good bearing capacity, enabling conventional shallow direct foundations in most projects. However, the low surface permeability characteristic of these formations can affect water management, although at greater depths relevant aquifers may be found; therefore, it is important to analyse the groundwater table before carrying out foundation works.

Seismicity in Fasnia is moderate, with 22 recorded events over 30 years and a maximum magnitude of 3.1, implying a low seismic risk in structural terms. There are no indications of karst or risks associated with expansivity, as the dominant soils are not clayey. Consequently, the main geotechnical constraint for the municipality is appropriate water management and a detailed study of lithological characteristics in order to optimise foundation solutions.
