Estudio geotécnico in Prats de Lluçanès

In Prats de Lluçanès, the ground is dominated by sandstones, conglomerates and flysch, which ensures a geotechnically widely competent substrate. These sedimentary formations, present very frequently, generally exhibit low permeability at the surface, although at depth aquifers with a somewhat greater development may be found. The bearing capacity of these soils is usually favourable for conventional foundations, although it is recommended to assess on a point-by-point basis the presence of interbeds with a higher clay content or localised alteration.

With regard to seismicity, with only one event in 30 years and a recorded maximum magnitude of 1.7, seismic activity is very low in the area and does not constitute a relevant constraint for structural sizing. Although expansive clays exist in a subordinate proportion and are generally located in areas of lower climatic risk, it is advisable to evaluate them if they appear locally in the foundation founding zones, although their influence is secondary compared with the set of dominant materials.
