Estudio geotécnico in Velilla del Río Carrión

In Velilla del Río Carrión, the subsoil is composed mainly of sandstones, conglomerates and flysch, with occasional shales, schists, as well as limestones and dolomites. These materials usually provide an adequate bearing capacity, although attention should be paid to areas where there is the presence of muds and peats of deltaic origin, as they constitute a support that is not very suitable for foundations and must be avoided as a bearing layer. The generally low permeability of the strata minimises the risk of seepage, facilitating the stability of conventional foundations, but localised shallow aquifers may exist.

Seismicity in the area is very low, with only 3 events over 30 years and a maximum magnitude (Mmax) of 2.2, which does not represent a relevant concern for structural design. Due to the presence of carbonate materials such as limestones and dolomites, there is a potential risk of karstification, so it is essential to check for the existence of cavities or dissolution processes before carrying out any foundation works. The non-clayey substratum rules out expansivity risks, with the main limiting factor being the possible occurrence of karst phenomena in the study area.
