Estudio geotécnico in Cualedro

In Cualedro, formations of sandstone, conglomerates and flysch predominate, followed by hard clays and marls, and less frequently slates and schists. These materials provide a firm and compact substrate, generally favourable for direct foundation, although the occasional presence of fine sands and silts, as well as muds and peats of deltaic origin, requires these latter to be discounted as a support layer due to their low bearing capacity and high compressibility. The rest of the soils, owing to their overconsolidated or cemented nature, usually provide good bearing conditions for most building uses.

Seismic activity in this municipality is moderate, with 44 events over 30 years and a maximum magnitude of 2.8, implying a low risk from the standpoint of structural design. The subsoil exhibits very low or no expansiveness, since the dominant substrate rules out the presence of expansive clayey materials, minimising this type of pathology in foundations. The main factor to consider in the geotechnical study is identifying areas with organic soft soils, which should be avoided when founding, prioritising as far as possible the hard and stable formations.
