Estudio geotécnico in Villamañán

In Villamañán, the geotechnical subsoil is mainly dominated by compacted gravels and sands, which generally provides excellent bearing capacity for buildings and civil engineering works. This soil type, together with the presence of fine sands, silts and formations of detrital origin such as sandstones and conglomerates, favours shallow or direct foundations in most cases, although it will be necessary to determine the local grading and uniformity of the ground. The presence of very productive aquifers also requires particular attention to the interaction between groundwater and the proposed foundations.

As regards seismicity, Villamañán exhibits considerable activity, with 200 recorded events over the last 30 years and a maximum magnitude of 4.7, which means that seismic criteria must be incorporated into the structural design of any project. In addition, the occasional presence of expansive clays in certain areas increases the local geotechnical risk, since they can develop significant heave under changes in moisture content. Thus, the main technical limitation for the geotechnical study in Villamañán will be determined by the need to map the presence of expansive clayey soils and to adapt the foundation solutions to the requirements of seismic resistance.
