Estudio geotécnico in Monfero

In Monfero, substrates of slates and schists predominate, covering more than 60% of the area, accompanied in smaller proportions by sandstones, conglomerates, flysch, and finally granite and gneiss. These materials generally exhibit low permeability, although shallow aquifers associated with altered zones may exist. These characteristics result in moderate bearing capacity, which makes it possible to propose solutions for shallow foundations in numerous areas, although detailed characterisation is recommended to assess the degree of fracturing and alteration.

Seismic activity in Monfero is very low, with just 3 events over 30 years and a maximum recorded magnitude of 1.9, so it does not constitute a relevant constraint for structural design. There are no signs of karstic processes or significant expansivity, since the non-clayey substrate rules out risks associated with expansive soils. The main element to be considered in any geotechnical study will be to ensure the correct characterisation of the supporting rock and the possible presence of friable zones that could affect ground uniformity during foundation construction.
